Transformation of the tobacco product market in Japan, 2011–2023

ObjectiveThis study updates a previous paper that examined trends in the sale of cigarettes and heated tobacco products (HTPs) in Japan between 2011 and part way through 2019. The current study includes complete unit sales data through 2023.MethodsData on cigarette and HTP sales were obtained from public sources available from the websites and stockholder reports for the Tobacco Institute of Japan, Philip Morris International and Japan Tobacco. We used joinpoint regression using the parametric method to test for trends in both per capita and total sales for the three outcome variables assessed between 2011 and 2023: (1) cigarette sales, (2) HTP sales and (3) combined cigarette and HTP sales. Joinpoint regression identifies changes in trends and estimates the annual per cent change (APC) for each trend segment.ResultsBetween 2011 and 2023, per capita and total cigarette sales declined by 52.6% and 52.7%, respectively. From 2011 to 2015, per capita cigarette sales in Japan decreased −1.5% APC; from 2015 to 2018, the decline accelerated to −10.5% APC and continued to fall −7.3% APC between 2018 and 2023. Between 2016 and 2018, per capita HTP sales increased by 149.0% APC, and since 2018, they have increased by 8.1% APC.ConclusionWhile many factors may account for the decreased sale of cigarettes in Japan over the past 12 years, the increased sale of HTPs appears to be a factor.

Performance and Evaluation of Hanski 227 Oriental Tobacco in Dak Lak Region, Vietnam from 2022 - 2024

With the results of selecting Oriental tobacco varieties suitable for natural conditions in Vietnam, with potential for raw material quality and raw material production capacity in Vietnam, from 6 oriental tobacco varieties originating from Bulgaria, the Tobacco Institute has been testing in Ninh Thuan province from 2019 to 2021, and Dak Lak from 2021 to 2022. The results of the trial planting show that oriental tobacco varieties are good growth, and are quite suitable for the soil and climate conditions in Ninh Thuan and Dak Lak provinces, and have selected 2 the best oriental tobacco varieties as Basma 16 and Hanski 227. In which, Hanski 227 variety is evaluated to have outstanding prospects due to its good growth ability, high yield, characteristic aroma and good smoking properties. The Hanski 227 variety has less harvested leaves, larger leaf size and mass than Basma 16 variety, so the labor costs for cultivation, harvesting and preliminary processing are lower. To evaluate the ability to expand the oriental area in Vietnam, we continue to trial planting the Hanski 227 oriental variety in Dak Lak in 2023 - 2024, with a fertilizer level and a planting density corresponding to 50N + 30P2O5 + 80K2O (N: NH4NO3, P: (Ca(H2PO4)2 and K: K2SO4) and 110,000 plants/ha. The experimental trial results show the Hanski 227 variety has good growth, high yield, and good quality, with yield fluctuating 1.52 - 1.66 tons/ha, nicotine content: 0.81 - 1.38%, and reducing sugar content: 8.9 - 12.1%, and the oriental material has a characteristic aroma and good smoking properties. Based on the trial results shows that the quality of Hanski 227 grown in Dak Lak are the same the oriental tobacco importing from Bulgaria, Türkiye and Greece. Therefore, the Dak Lak province is the most suitbale region for producing good quality oriental tobacco in Vietnam compared to Ninh Thuan region. Because materials in Ninh Thuan has the high clorua content reducing material quality. In 2025, we continue to grow the Hanski 227 oriental tobacco variety in Dak Lak region on a large area and complete the preliminary processing process, with the goal of producing Oriental tobacco raw materials domestically, with appropriate production costs.

Analysis and Evaluation of Tar and Nicotin Content in some Cigarette Products of Vietnam in 2023

Tobacco is one of the biggest public health threats facing the world in general and Vietnam in particular. More than 8 million people around the world die from tobacco-related diseases. There are about 70 carcinogens in cigarettes, in addition to addictive, cytotoxic, mutagenic active ingredients,... Among them, Tar and Nicotin are the biggest dangers affecting people health in cigarette smoke. In the study, analysis of Tar and Nicotin content in 166 cigarette samples taken from 10 cigarette manufacturing companies in Vietnam was performed. Analytical results show that Tar content ranges from 1.67 to 15.1 mg/cigarette; Nicotin content ranges from 0.37 to 1.35 mg/cigarette. These results are all lower than the maximum allowable limit according to QCVN 16-1:2015/BYT, but there are some samples with Tar and Nicotin content close to the asymptotic level. This analysis result is also consistent with reports of Tobacco Institute Company Limited in recent years. Although the Tar and Nicotin contents in the samples do not exceed the maximum limit according to QCVN, they are much higher than other countries in the world. Therefore, it is necessary to propose appropriate routes to reduce Tar and Nicotin to ensure the health of users.

The Institute, the Archive, and the Smoke-Filled Room

Archived tobacco industry documents reveal a relationship in the 1970s and 1980s between the author of a first-year writing textbook and the Tobacco Institute, a tobacco industry trade group. I present details of this relationship to argue for an expanded account of institutional influence on rhetoric and writing studies.

Results of Trial Transplanting of Oriental Tobacco Varieties in Dak Lak Province, Vietnam in 2022

In 2022, the Vietnam Tobacco Institute continued to test 6 tobacco oriental varieties in Dak Lak province based on the test results of tobacco varieties, cultivation techniques, curing in Ninh Thuan and Dak Lak provinces in 2021. To determine the suitable growing areas and varieties of oriental tobacco for the Dak Lak region, we experimented with six oriental tobacco varieties, including Basma 16, Kozarsko, Hanski 227, Rila 89, Dupnitsa 733 và Basma X with a fertilizer rate of 40N: 30P2O5: 50K2O kg/ha. The variety experiment was designed with a completely randomized block, repeated 3 times with 50 m2/plot. The experimental results have determined Dak Lak region to be suitable for planting the oriental tobacco plants and have selected two of the property oriental varieties as Basma and Hanski 227. Those varieties were good growth, high yield and good quality. The quality of oriental tobacco production in Dak Lak region was quite good, equivalent to the imported samples which was been used by Vietnam’s factories. In the coming time, the Vietnam Tobacco Institute will continue to experiment and expand the oriental tobacco area in Dak Lak to provide materials for cigarette factories and limit imported tobacco from abroad.

Inheritance of yield-related morphological characteristics in F1 tobacco hybrids

The aim of this work was to study the mode of inheritance of the number of leaves per stalk and the length, width and area of the leaves from the middle part of the stalk - traits directly related to the yield in the offspring of the first generation. The studies were made with four mother parent tobacco varieties of different types (three of the Prilep type: P-23, ? 18-50/4, ? 76/86 and one of the Basmak type - ?? 8/1), one pollen donor parent Burley B-1-91, and their four F1 hybrids. The crosses were made in 2018, 2019 and 2020, and the experiment with the parent genotypes and their hybrids was set up in 2019, 2020 and 2021, on a field trial at the Scientific Tobacco Institute - Prilep in a randomized block design with four replications. All appropriate cultural practices were applied during the growing season. The research data indicates that there was no heterosis in the hybrids for the studied traits. The partially dominant mode of inheritance is an indicator of good successive selection of individuals in future generations and quick fixation and stabilization of the traits. The hybrids MS 8/1 ? B-1/91 and P 18-50/4 ? B-1/91 represent very interesting material for future tobacco breeding activities.

Results of Trial Oriental Tobacco Varieties Planting in Ninh Thuan and Dak Lak Province, Vietnam in 2021

The oriental tobacco trial was planted to evaluate the possibility of producing Oriental tobacco in Vietnam. Vietnam Tobacco Institute tested six oriental tobacco varieties in Ninh Son district under Ninh Thuan province in 2019 - 2020. Those varieties originated from Bulgaria country were bred and multiplied for other countries researching the adaptability of variety. The test results showed that oriental tobacco varieties were good growing and proper for soil and climate conditions in Ninh Thuan province. Using the trial varieties selected, we have collected the best two varieties to expand the growing area in Ninh Thuan and Dak Lak provinces in the year 2021, including the Basma 16 and Hanski 227 varieties. In 2021, we tried the Basma 16 with a planting density of 280.000 plants/ha, and Hanski 227 was 110.000 plants/ha. Based on results of the soil analysis, the fertilizer formula in Ninh Thuan province consisted of 2 levels as PB1 (30N + 0P2O5 + 50K2O kg/ha) and PB2 (40N + 0P2O5 + 50K2O kg/ha); whilst for Dak Lak province, the fertilizer formula was PB1 (30N + 30P2O5 + 50K2O kg/ha), PB2 was 40N + 30P2O5 + 50K2O kg/ha with N: (NH4NO3), P: (Ca(H2PO4)2) and K: (K2SO4). The experiments were pairs designed, with every formula of 500 m2. The trial results of 2021 showed that in two levels of fertilizer, the dry yield, nicotine content, sugar content, and chlorine content of oriental tobacco varieties in Ninh Thuan province ranged from 1.44 - 1.70 tons/ha, 0.68 - 1.33%, 19.2 - 22.2%, and 1.41 - 1.80%; meanwhile in Dak Lak province were 1.57 - 1.82 tons/ha, 1.0 - 1.39%, 9.8 - 12.0%, and 0.27 - 0.31%. Based on the results analysis of chemical compositions in tobacco leaves and smoking properties, the oriental tobacco in Dak Lak has good quality and was similar to the oriental tobacco imported from Bulgaria, Turkey and Greece countries. In contrast, in Ninh Thuan, oriental tobacco was not having good quality but hot smoke and poorly burning. So, the Dak Lak province was a good region for oriental tobacco in Vietnam with formulas of trial fertilizer above applied. In 2022, we will continue to expand the growing areas of oriental tobacco in Dak Lak province to limit the importation of oriental tobacco products from foreign countries.

Tobacco industry thwarts ad ban legislation in India in the 1990s: Lessons for meeting FCTC obligations under Articles 13 and 5.3

Bans on tobacco advertising are important for reducing tobacco-caused disease. Previously secret internal tobacco industry documents and organizational and newspaper websites related to tobacco control efforts in India during 1990s were analyzed. The Ministry of Health and Family Welfare, World Health Organization, Indian Council of Medical Research, and civil society played important roles in pushing for tobacco control legislation beginning in the 1980s. Guided by transnational tobacco companies, especially British American Tobacco, Philip Morris International, and RJ Reynolds, Indian cigarette companies formed the Tobacco Institute of India (TII). Following the industry’s global strategy, TII proposed voluntary advertising codes, used diplomatic channels and high level political and judicial lobbying, and allied with other industry, sports and trade groups to delay legislation for ten years. TII argued for the social and economic importance of tobacco and that laws were unnecessary, unconstitutional, and would hurt the economy. These early global strategies were continuing in 2022 to delay and evade legislative efforts to ban tobacco advertising. Understanding these strategies can inform public health efforts to counter industry efforts to thwart the WHO Framework Convention on Tobacco Control in 2022 not only in India, where the Ministry of Health and Family Welfare has proposed strengthening India’s tobacco control law, but globally.

Building Process of Potato Virus Y (PVY) Management on Tobacco Plants in the Northern Vietnam

In recent years, some viral diseases have been increasing in the tobacco-growing regions of Vietnam and causing serious damage to the tobacco yield and quality. If it has no effective control, the viral diseases will injure serious harm in the tobacco field next time. Based on the research results in the prevention of viral diseases from 2016 to 2021, the Vietnam Tobacco Institute has built a process to control Potato Virus Y that harms the tobacco plants in Vietnam. During the experiment and application in tobacco cultivation practice, the process was effective against PVY disease. The application of the process, the disease rate and disease index of PVY were significantly reduced in the tobacco field, contributing to increasing yield, quality, and income for tobacco farmers. The insecticides and antivirus drugs made according to the process have increased their effectiveness, do not harm the growth and development of tobacco plants, little have residues in tobacco production. This process can control many other viral diseases on tobacco plants.

Use of Antiviral Virucides in the Prevention of Some Viral Diseases Causing on Tobacco Plants in Vietnam

In recent years, some viral diseases have been increasing in the tobacco-growing regions of Vietnam and cause serious damage to the tobacco yield and quality. If it has not an effective control, viral diseases will injure seriously in the tobacco field in next time. To control the effect of viral diseases, study use of some antiviral virucides is necessary on tobacco plants. In 2021, Vietnam Tobacco Institute experimented with the effective control of Ditacin 8SL, Sat 4SL, and Exin 4.5SC for TMV, CMV, PVY, and TNRV on the tobacco field in Bac Giang province. Results of the study show the antiviral agents are effective in the control of the virus disease on tobacco. When only spray Ditacin 8SL, effective prevention for viral diseases ranges from 22.4 - 30.3%; Sat 4SL: 5.5 - 30.2%, and Exin 4.5SC: 8.2 - 24.1%. Spraying a mixture of antiviral agents and insecticides gives higher efficiency than spraying a kind. For example, spray Ditacin 8SL + Confodor 100SL, effective control reaches from 34.3 to 100%; Sat 4SL + Confidor 100SL: 32.6 - 92.3, and 38.5 - 100% with Exin 4.5SC + Confidor 100SL. The spray treatments have a higher yield and quality than the control without spraying.

Review of Illicit Tobacco Trade Policy and Program Implementation in the Philippines

Tobacco is the leading risk factor driving death and disability across all ages in the Philippines, based on the Global Burden of Disease Study in 2019, rising from the second-highest in 2009 (Institute for Health Metrics and Evaluation, 2020). In 2019, around 112,000 deaths in the Philippines are attributable to tobacco (Institute for Health Metrics and Evaluation, 2020). Economically, the Philippines was estimated to be spending Php 269.3 billion in 2012 on healthcare and productivity losses attributable to smoking. This is equivalent to 2.5% of the country’s Gross Domestic Product that year (Campaign for Tobacco-Free Kids, 2020). Government efforts in countering illicit trade have been said to be uncoordinated and poorly implemented (Organisation for Economic Co-operation and Development, 2018). Further, reports on actual policy implementation are lacking. In the Philippines, there are few to no reports and studies on the localization and disaggregation of regional data on illicit tobacco trade. This study aims to review the policies and program implementation on illicit tobacco trade in the Philippines in relation to The Protocol to Eliminate Illicit Trade in Tobacco Products or Illicit Tobacco Protocol (ITP). This study is divided into two parts. The first part involves policy and stakeholder analysis; the second part focuses on the program implementation. Based on a rapid scan of online government databases, a total of twelve government policies related to the prevention of tobacco illicit trade were extracted for review from which five were Republic Acts, three were implementing guidelines, two were revenue regulations, a memorandum circular and a presidential decree. Notably, these are only available in each agency’s repository. For the review of programs, a total of eight participants were recruited to participate in the study. The participants represent various agencies and levels of governance: Civil Society, Local Government Unit, and a National Government Agency. The researchers conclude that the Philippines is still ill-prepared in combating illicit tobacco trade. In the context of programs and policies, however, there is huge potential for the government agencies to collaborate and strengthen their core strategies. In comparison to the ITP, many Philippine policies are partially compliant. Many of the mechanisms in place are working for each agency’s objectives, but fail to address the illicit trade at the macro level with its fragmentation. These include not only policy development, but also monitoring. In the event these crucial gaps are ironed out, acceding to the ITP will remarkably benefit illicit tobacco trade control and serve as a catalyst for developing agency policies. This study identified unique characteristics in the policy environment and implementation of illicit tobacco trade. In the Philippines, WHO FCTC Article 15 appears to be (and should be) largely managed by BIR in view of taxation. However, having a better appreciation of illicit trade from the perspectives of health, trade, regulation, law enforcement, and crime reduction, local government can bring to light new approaches and ways to communicate this issue. Moving forward, the researchers recommend to (1) focus on policy gaps, (2) establish an inter-agency framework to strengthen inter-agency coordination, (3) establish a reporting mechanism and monitoring framework, (4) implement best practices and strategies, (5) boost and conduct further research, and finally, (7) accede to the ITP to strengthen Philippine capacity in combating illicit tobacco trade.

30th anniversary of Australian legal ruling on second-hand smoke

Before the 1990s, where people smoked was generally unrestricted. Legislation prohibited smoking near explosives or flammable materials, in other hazardous areas, and in some but not all confined spaces. Smoking was largely unrestricted in many work places and most public spaces, such as theatre foyers, pubs, clubs, restaurants, and hotel rooms. In Australia, all this changed after Federal Court Justice Trevor Morling handed down judgment on Feb 7, 1991, in Australian Federation of Consumer Organisations Inc (AFCO) versus the Tobacco Institute of Australia Limited (TIA). The court found that second-hand smoke causes lung cancer in non-smokers and asthma attacks as well as respiratory disease in children. The decision was the first of its kind by a superior court anywhere in the world.

Nasledqvane na visochinata na rasteniqta i broq na listata pri hibridni combinacii tutun Virdjinia

The aim of current research is to determine genetic effects in relation to inheritance of plant height and leaves number regard to their use for the Virginia tobacco breeding. The experimental work was carried out on the field of the Tobacco and tobacco products Institute, Markovo, Bulgaria. Coefficient of heritability and selection, the number of genes, transgressions and heterosis of plant height and leaves number were studied. For this purpose P1, P2, F1 and F2 populations of seven hybrid combinations were analyzed. The data from conducted analysis showed that inheritance of the plant height and tobacco leaves number is overdominantly, in the direction of the parent with the higher trait values. The number of genes influencing the plant height expression varies in a wide range (14-17) and genes number affecting tobacco leaves is 1 or 2. Negative epistasis was observed for the plant height inheritance, while epistatic interactions of genes controlling leaves number was weaker but positive one. There were establish high values for heritability coefficient of plant height and average one of leaves number. Based on the conducted analysis it was found that the mass selection by phenotype for studied traits would be more effective in the F5-F6 hybrid generations.

What Is Accounting for the Rapid Decline in Cigarette Sales in Japan?

This study describes how trends in the sale of cigarettes in Japan between 2011 and 2019 correspond to the sales of heated tobacco products (HTPs) that were introduced into the Japanese market in late 2015. Data used for this study come from the Tobacco Institute of Japan and Philip Morris International. The findings show that the accelerated decline in cigarette only sales in Japan since 2016 corresponds to the introduction and growth in the sales of HTPs.

HELICOVERPA ARMIGERA-PEST ON TOBACCO PLANTS

Helicoverpa armigera Hubner is а migratory, cosmopolitan and polycyclic species. The pest is known as tobacco bollworm or budworm. The species is polyphagous and is an economically important agricultural pest. The studies were conducted on tobacco plants in the Experimental Field of the Scientific Tobacco Institute - Prilep during 2017/2018. Monitoring of population dynamics of H. armigera was performed during tobacco vegetation in a 10 -day period, using the method of examining 100 tobacco plants, with Zig-Zag review of pest scouting. The collected larvae were additionally fed and grown in a laboratory according to the standard laboratory methodology. Field and laboratory trials were carried out for control of H. armigera, with five insecticides/ active ingredients: Spinetoram (a.i. 250 g/kg)- 0.3 kg/ha, Indoxacarb (a.i. 150 g/L)- 0.3 L/ha, Metaflumizone (a.i 240 g/L)- 1 L/ha; Emamectin (a.i. 9.5 g/kg)- 2 kg/ha and Flubendiamide (a.i. 480g/L)- 250 g/ha. Larvae of tobacco budworm damage flowers, seed capsules and top tobacco leaves. The population dynamics of H. armigera showed that the species was present on tobacco from the beginning of July (when plants produce flowers) until the end of tobacco vegetation. The population was the most numerous in August and reached its highest level of density on 20th August in both years. In field trials, were determined five predatory species that fed with young larvae of H. armigеrа: Chrysopa formosa (Neuroptera, Chrysopidae), Chrysopa perla (Neuroptera, Chrysopidae), Chrysopa carnea (Neuroptera, Chrysopidae), Coccinella septempunctata (Coleoptera, Coccinellidae) and Adonia variegata (Coleoptera, Coccinellidae). In the beginning of October on tobacco plants we found parasitized larvae of H. armigera. In laboratory conditions parasitized larvae ate less and ceased developing at their 4th stage- L4. In each parasitized larva was developed one parasite species of Hyposoter didymator (Hymenoptera, Ichneumonidae). H. didymator is endoparasitoid wasp, and it lives on host tissues. According to field and laboratory trials during 2017/2018, all applied insecticides showed high efficacy in H. armigera control. The highest average mortality of 100% was caused by insecticides: Spinetoram, Indoxacarb and Emamectin. Flubendiamide had 97.5% efficiency in control of this pest, and the insecticide Metaflumizone 95.0%. This pest represents a significant challenge to tobacco filed and it produces high economic losses of tobacco seed each year. For the control of H. armigera, it is required constant monitoring of the lifecycle of the pest. One part of management strategy is to study parasitoids, predators and microorganisms and use them against H. armigera. Chemical control is still the most reliable and economic way of protecting tobacco crop from tobacco bollworm.

CHARACTERISTICS OF THE NEWLY CREATED GENOTYPE OF VIRGINIA TOBACCO LINE V79/09 CMS F1 IN THE REGION OF PRILEP DURING 2012-2016

V-79/09 CMS F1 is a hybrid male sterile line created in the Scientific Tobacco Institute - Prilep in 2009 by intervariety hybridization. It was included in comparative trials in the period 2012/2016, performed at the Experimental field of the Tobacco Institute, along with introduced varieties as a check. Through the whole period of investigation, line V-79/09 CMS F1 showed better biomorphological and productional properties compared to the check varieties. Due to its characteristics, it surpassed all other varieties and lines included in the investigation. Thus, the line starts to flower in 71.8 days, 50% flowering occurs in 76.6 days and end of flowering in 81.8 days from the date of planting. The average length and width of the 5th leaf are 52.1 cm and 36.8 cm, of the 10th leaf 69.3 cm and 39.9 cm, and of the 15th leaf 64.7 cm and 35.1 cm, respectively. Height of the stalk with inflorescence averages 213 cm and the number of leaves is 34.0. The yield was 3450 kg/ha, but it should be mentioned that throughout investigation, the line V-79/09 CMS F1 showed statistically significant differences compared to the check varieties. All these characteristics make this line interesting for tobacco industry.

SEED CHARACTERISTICS OF SOME ORIENTAL TOBACCO VARIETIES DEPENDING OF THE TRANSPLANTING DENSITY

The transplanting density is a very important factor when it comes to the acquisition of the planned yield of seed with appropriate quality taken from the certified tobacco seed plots. The main goal of this research was to establish tobacco seed yield and quality given by the tobacco planted with various transplanting density. The experiment was set in the Experimental Field of Scientific Tobacco Institute - Prilep. Further analyses of seed quality characteristics were performed in the accredited Laboratory for seed quality control of agricultural plants. The analyses were performed on two varieties of oriental tobacco type Prilep: P-66-9/7 and NS-72 in different transplanting variants: 50x15cm, 45х15 cm and 40х15cm. The area was prepared with the usual agro technical measures for tobacco seed plots for certification. The transplanting was performed manually in 5 repetitions. Morphological measures were performed on 10 plants of each tobacco varieties and variant of density of transplanting. The following morphological characteristics were analyzed: height and width of the stalk, height and width of fruit, and height and width of capsule. Also the weight of the fruit was analyzed together with the number of capsules in the fruit and the seed amount in the fruit of every stalk. After seed harvest and processing, the morphological measurement and laboratory analyses for seed quality were performed concerning the seed germination expressed in percentage and the apsolute weight expressed in grams. We can conclude that the seed given by a stalk which has growth on larger vegetation area produces better values concerning the yields and quality. The tobacco variety P-66-9/7 has average value of 13.68 g, NS-72 variety has 15.51 g. Which means that the stalks which growth on smaller vegetation for example P-66-9/7 has average value of 5.36 g and NS-72 has 6.76 g. Insignificant number of the results have shown a digression but it can be concluded that the seed obtained by the plants grown in larger vegetation area produce seed with better characteristics considering the quality and quantity of the seed.

VARIABILITY OF THE MOST IMPORTANT QUANTITATIVE PROPERTIES IN SOME VARIETIES OF TOBACCO TYPE BURLEY

The morphological properties that characterize the type of tobacco or the variety in one type are known as qualitative and quantitative. The quantitative properties are regularly conditioned from the impact of a larger number of genes and also they depend from the environment factors. The investigations are done in 2015 on experimental field in the Scientific Tobacco Institute in Prilep, with four repetitions with following varieties: Posejdon (control), BD-1, B-1246 and one new perspective line DP-1710. The aim of this investigationes is to show the variability of the most important quantitative properties: height of the plant with inflorescence, the number of leaves per plant and the length and width of the biggest and the smallest leaf from the middle harvesting belt in tobacco type Burley. The results from the research are processed statistically by these parameters: average value (x̄), average value error (Sx ), standard deviation (S), variation coefficient (CV) and variation width (WV). From the research, we established that the subject varieties are stable enough, the variability is very low because everywhere the variation coefficient was lower than 10%. However, the newly created line DP -1710 is with the slightest variation in the tested properties. Among other things, it is on average the highest (x̄ = 188 cm) and has the largest leaves (x̄ = 63 cm), which is a positive feature in coarse tobacco of this type.
