Reaction and quantification of damage in pineapple parasite by Meloidogyne spp.

Four pineapple cultivars (Vitória, Smooth Cayenne, Pérola and MD-2 (Gold)) were inoculated M. javanica and M. enterolobii in two experiments. In the first, sixty days after planting the seedlings, the plants were inoculated with 5,000 eggs + juveniles of the second stage (J2) of M. javanica or M. enterolobii, in a completely randomized design (CRD) with 10 replications. After 90 days of inoculation, we evaluated: a fresh matter of the root system, the final population and reproduction factor of nematodes (RF). Cultivars with RF≥1.00 were considered susceptible and with RF<1 resistant. Smooth Cayenne cultivar was susceptible to both nematodes. In the second experiment, pineapple cv. Smooth Cayenne was inoculated with increasing levels of M. enterolobii (0, 2,500, 7,500 and 15,000 eggs+J2) in DIC with 8 replications, aiming to quantify the damage caused to plants by the nematode. The weight of the fruit per fruit, weight of the peel, weight of the juice, weight of the fruit without the crown, median diameter of the fruit, a diameter of the central axis of the fruit, the height of the fruit and titratable acidity were evaluated. The higher the population level of M. enterolobii, the lower the recorded values ​​of the evaluated variables.

Antifungal activity of three different varieties of Capsicum annuum against clinical isolates of Candida species

ObjectiveAcquired resistance to antifungal agents is rising among Candida species. Herbal extracts including Capsicum annum extracts have biological profits, which can be employed to overcome drug resistance in fungal species. The present study investigated the efficacy of different varieties of C. annum extracts against Candida species.MethodsAqueous and alcoholic extracts of three different varieties of C. annum were prepared using the succulent method. Total values for compound extracts of C. annum var. cayenne, C. annum var. cayenne cultivar sabzevari, and C. annum var. cerasiforme were 43, 42, and 38 g, respectively. The clinical Candida isolates including C. albicans (n = 13), C. dubliniensis (n = 2), C. parapsilosis (n = 2), and C. tropicalis (n = 1); and reference strains of C. albicans (TIMML 1292 and TIMML 183), C. krusei (TIMML 1321), C. parapsilosis (TIMML 2201), and C. tropicalis (TIMML 731) were examined based on the M27-A3 guideline.ResultsAqueous and alcoholic extracts of Capsicum annum showed a minimum inhibitory concentration (MIC) range of more than 512 µg/ml against clinical and reference strains of Candida. There was no justifiable difference between the effects of these extracts on Candida species.ConclusionBoth aqueous and alcoholic extracts of Capsicum annum could not exert a significant effective impact on clinical and reference strains of Candida. The difference in pepper spiciness did not show a significant role against Candida isolates. However, their possible effects might be different among other yeasts or filamentous fungi.

Pineapple genetic diversity in Riau peat land assessed by Random Amplified Polymorphic DNA (RAPD) marker

Riau is one of the centers for pineapple production in Indonesia and harbored many local cultivar that have been cultivated for generations. The purpose of this study was to investigate the genetic diversity and genetic similarity between local cultivar in Riau based on RAPD (Random Amplified Polymorphic DNA) markers. Diversity analysis was carried out on ten local pineapple cultivar from five districts, namely Kampar, Indragiri Hilir, Siak, Bengkalis, and Dumai, using 11 RAPD primers. The PCR amplification result of the 11 RAPD primers selected generated a total 77 loci and the percentage of polymorphic loci was 96.42%. The high value of percentage of polymorphic loci reflected high diversity of pineapple in Riau propince. The values of genetic similarity coefficient of the pineapple genotypes in Riau Province ranged from 53% to 91%. The UPGMA dendrogram displayed that the Queen and Smooth Cayenne cultivars were separated in different cluster, while the Gemilang cultivar (GT) was placed between the Smooth Cayenne and Queen groups. This finding confirmed that Gemilang cultivar was the result of the natural crossing pollination between Smooth Cayenne and Queen pineapple.

Pineapple is one of important fruit crops in Indonesia. One of important problems in pineapple production is pest infestation.. This study aims to investigate the biology, demography, and life cycle of Dolichotetranychus floridanus Banks on two pineapple cultivars (Queen and Cayenne). Observation of mite development (eggs-adults) were conducted every 6 hours. Adults were observed everyday to record the fecundity. The life table was constructed from the survivor and fecundity of D. floridanus. Based on this table, the variables of population growth, including gross reproduction rate (GRR), net reproductive rate (R0), mean generation time (T) and increase intrinsic rate (r) were determined. The results showed that the GRR, R0, and r of D. floridanus in the Queen cultivar were higher than Cayenne cultivar, while the T in the Queen cultivar was lower. Queen cultivar more suitable for D. floridanus than Cayenne cultivar.

Influence of Watering Solution and Phenotype on the Growth of <i>in Vitro</i> Propagated Pineapple (Smooth Cayenne Cultivar) Plantlets during Acclimatization

Pineapple is the first fruit crop cultivated in south Benin that greatly contributes for food and nutritional security and farmers’ income. But the lack of homogenous planting material constitutes the major constraint for improving pineapple yield. In vitro micropropagation is now used in the production of homogenous and free disease planting materials of pineapple. However, the acclimatization to natural condition of pineapple plantlets is an important step in planting material production of this crop. Here, we determined the intrinsic and extrinsic factors which influence the behavior of plantlets during the acclimatization process. For this purpose, plantlets from different categories were selected, trimmed and planted on a horticultural substrate made up of potting soil, white sawdust and compost previously sterilized. The plantlets were then incubated in under acclimatization greenhouse with average temperature of 29˚C and 70.2% of humidity. A batch of plantlets was subjected to two different watering solutions: Shive and Robbins solution and NPK 14-6-5 foliar fertilizer. The results obtained initially showed high rate (100%) of survival and growth of the plantlets watered with Shive and Robbins solution against 50% of the plantlets watered with the foliar fertilizer solution. In addition, the plantlets with spread pores exhibiting the characteristics of which the number of leaves varies between 9 and 11, the weight between 1.2 and 1.5 g, the size of 4.5 to 5.5 cm, and a good junction between the aerial part and the root system were those which were successfully grown in acclimatization phase under greenhouse, unlike plantlets with erected pores having lower success rate. This study goes a long way in providing good procedures of acclimatization of homogenous and free disease planting material of pineapple to the famers.

BIOACTIVE COMPOUNDS AND ANTIOXIDANT ACTIVITY OF PINEAPPLE FRUIT OF DIFFERENT CULTIVARS

ABSTRACT Pineapple is widely consumed and appreciated not only due to its taste and aroma, and also to its nutritional, functional and antioxidant properties, including its vitamin C and carotenoid contents. Brazil is one of the largest world’ pineapple producer, and Pérola and Smooth Cayenne cultivars are the most commonly grown and marketed, but their susceptibility to fusariosis can compromise cultivation. New cultivars resistant to this pathogen are available to meet the demands of pineapple producers and consumers. The aim of this study was to evaluate the content of bioactive compounds and antioxidant activity of pineapple fruits of Imperial, Victoria, IAC Fantástico and Gomo de Mel cultivars, as well as traditional Pérola and Smooth Cayenne cultivars. Fruits grown in the Triângulo Mineiro region were evaluated by colorimetry, determination of ascorbic acid and phenolic compounds by spectrometry, antioxidant activity by ABTS and carotenoid profile by HPLC. Regarding color, Gomo de Mel cultivar showed lower brightness and higher value of parameter b*, indicating a more intense yellow color in this fruit. This result is consistent with the highest carotenoid concentration in this cultivar. Another cultivar that stood out was Imperial, which, while maintaining high carotenoid levels, also showed high concentrations of vitamin C and phenolic compounds, and higher antioxidant activity. Victoria cultivar showed low levels of bioactive compounds and antioxidant activity, even lower than IAC Fantástico cultivar, which showed levels of bioactive compounds similar to traditional Pérola and Smooth Cayenne cultivars.

Avanços na fruticultura tropical no Brasil

Os principais aspectos que marcaram a evolução técnica das culturas do abacaxizeiro, mamoeiro e maracujazeiro no Brasil foram discutidos. Em abacaxizeiro, tem-se constatado uma inovação no sistema de comercialização da cv. Smooth Cayenne, que consiste no uso de caixas de papelão ondulado para o mercado interno, cujo objetivo é propiciar uma garantia de sabor inserida em uma marca. O recente lançamento de cultivares resistentes à fusariose, pela Embrapa (Imperial e Vitória) e IAC (Fantástico), traz novas perspectivas de produtividade. Em maracujazeiro, a maior contribuição aos pomares foi dada pelo melhoramento genético, inicialmente voltado apenas para ampliação da produtividade da cultura. No início dos anos 2000, o lançamento das primeiras cultivares de maracujá - mais produtivas e com qualidade de fruta diferenciada para os dois segmentos de mercado (frutas frescas e agroindústria), transformou o cenário produtivo brasileiro. Com a criação de um sistema organizado de produção e comercialização de sementes e mudas selecionadas, ampliou-se significativamente a qualidade dos pomares. Atualmente, a disponibilidade de novas cultivares tolerantes à virose (VEFM) e cultivares regionais passou a representar um diferencial para a cultura. Em mamoeiro, destaca-se a ocorrência do Mosaico do Mamoeiro (Monte Alto-SP, 1967), que determinou a migração da cultura pelo Estado e sua expulsão para outros estados, até sua fixação na Bahia e no Espírito Santo, os maiores produtores nacionais. Comparam-se as técnicas utilizadas nos diferentes períodos de produção, antes e depois do surgimento do mosaico, que permitiram ao Brasil lançar-se no mercado externo, tornando-se o maior exportador mundial de mamão, com lavouras produtivas e frutos de ótima qualidade. Nesta evolução, soma-se a contribuição do melhoramento genético, que disponibilizou sementes de alta qualidade, com reflexos nas práticas culturais e de propagação. São apresentadas de colheita e de pós-colheita diferenciadas que resultaram em melhorias no padrão de qualidade das frutas exportadas para o mercado europeu e norte-americano.

PROTEOLYTIC ACTIVITY IN STEMS OF 'VITÓRIA', 'SMOOTH CAYENNE' AND PÉROLA' PINEAPPLE PLANTS

Helber B. Costa, S.G. Delboni Frederico S. Fortunato Univix Rua Jose Alves, 301 (Goiabeiras) 29075-080 – Vitoria, ES - Brazil Jose A.Ventura Incaper Rua Afonso Sarlo, 160 (Bento Ferreira) 29052-010 - Vitoria, ES – Brazil ventura@incaper.es.gov.br Keywords: Ananas comosus var. comosus , genotypes, bromelain, proteolytic enzymes Abstract Pineapple is one of the most important tropical fruits, not only due to its quality as fresh and processed product, but also as a source of subproducts such as bromelain, a proteolytic enzyme mixture with large applications in pharmaceutical and food industries. Looking for solutions of disease problems, Brazilian research institutions have developed new pineapple cultivars such as the ‘Vitoria’, released for farmers’ use in the State of Espirito Santo in 2006. ‘Vitoria’ plants are resistant to fusariosis, the main pineapple disease in Brazil, and show agronomic characteristics similar or even superior when compared to the traditional cvs. Perola and Smooth Cayenne. In this work were determined the total protein contents and the proteolytic and specific activities of proteolytic enzymes in pineapple stems of cvs. Vitoria, Perola and Smooth Cayenne. Results indicate that the new cv. Vitoria presented protein and enzymatic values in stem tissues similar to those found in the Smooth Cayenne cultivar. INTRODUCTION Pineapple ( Ananas comosus var. comosus) is a monocot plant of the Bromeliaceae family, and presents a fruit symbolic for tropical and subtropical regions, of great acceptance throughout the world as both fresh and processed fruit. The fruit is rich in a group of proteolytic enzymes, known by the general name of bromelain, which is also present in other parts of the pineapple plant. Bromelain has wide application in the food industry, but it has also clinical use for many different purposes, such as antitumoral agents, immune modulation, cleaning of wounds, increase of antibiotic effect, mucolitic action, aid in digestion, applications in cardiovascular and circulatory illnesses, surgical procedures and treatment of wounds of skeletal musculature. Moreover, bromelain has anti-inflammatory effect (Cooreman et al., 1976). Enzymes catalyze reactions in biological systems and have a extraordinary catalytic efficiency superior to that of chemical catalyzers. They also speed up specific chemical reactions and remain functional in watery solutions and conditions of small variation of temperature and pH (Voet and Voet, 1995). The proteolytic enzymes or peptidases make up about 50% of industrially used enzymes (Garcia-Carreno and Del Toro, 1997). The bromelains are hydrolases that cleave peptide bounds for water addition and belong to the subclass of cysteine (or tiol) peptidases, as they present a residue of cysteine. The wide use of bromelain in pharmaceutical industries, cosmetics and food increases the importance of studies to evaluate proteolytic activities in different cultivars

Intra-specific DNA polymorphism in pineapple (Ananas comosus (L.) Merr.) assessed by AFLP markers

Pineapple (Ananas comosus (L.) Merr.) cultivars, often derived from somatic mutations, are propagated vegetatively. It has been suggested by isozyme data that there is little genetic variation among Smooth Cayenne cultivars. A thorough investigation of the genetic variation within the cultivated speciesAnanas comosus, particularly among commercial cultivars, will provide critical information needed for crop improvement and cultivar protection. One-hundred and forty-eight accessions ofA. comosus and 14 accessions of related species were evaluated with AFLP markers. The average genetic similarity ofA. comosus was 0.735 ranging from 0.549 to 0.972, suggesting a high degree of genetic variation within this species. With AFLP markers, discrete DNA fingerprints were detected for each commercial cultivar, breeding line, and intra-specific hybrid. Self-incompatibility, high levels of somatic mutation, and intraspecific hybridization may account for this high degree of variation. However, major cultivar groups of pineapple, such as Cayenne, Spanish, and Queen, could not be distinctively separated. These cultivar groups are based on morphological similarity, and the similar appearance can be caused by a few mutations that occurred on different genetic background. Our results suggest that there is abundant genetic variation within existing pineapple germplasm for selection, and discrete DNA fingerprinting patterns for commercial cultivars can be detected for cultivar protection. The genetic diversity and relationships of fourAnanas species are also discussed.

Resposta de plantas micropropagadas de abacaxizeiro à inoculação de bactérias diazotróficas em casa de vegetação

O objetivo deste trabalho foi selecionar e avaliar bactérias diazotróficas isoladas de abacaxizeiro (Ananas comosus (L.) Merril) no desenvolvimento de cultivares micropropagadas da mesma espécie em casa de vegetação. Plantas da cultivar Perolera foram submetidas à inoculação com Asaia bogorensis (AB219) e cultivadas em tubetes, durante 145 dias, com as misturas: casca de arroz carbonizada, folha de carnaubeira triturada e vermicomposto; casca de arroz carbonizada, pó da casca do coco maduro e vermicomposto; casca de arroz carbonizada, vermiculita e vermicomposto. Plantas da cultivar Primavera receberam inóculos com o AB219 e bactérias relacionadas a Burkholderia cepacia (AB202 e AB213), enquanto plantas das cultivares Pérola e Smooth Cayenne receberam AB219 e AB213, sendo cultivadas, por 140 dias, em tubetes com a mistura de vermicomposto e vermiculita. A colonização dos abacaxizeiros pelas bactérias diazotróficas foi confirmada. As plantas da cultivar Perolera cresceram melhor em casca de arroz carbonizada, vermiculita e vermicomposto e responderam positivamente ao AB219. Já as plantas da cultivar Primavera não apresentaram resposta significativa à inoculação com AB219, AB202 e AB213. Houve incremento de 23,1% a 38,5% na matéria seca de raízes das plantas da cultivar Pérola na presença de AB213 e AB219, respectivamente. A presença de AB213 incrementou em 15,2% a matéria seca da parte aérea das plantas da cultivar Smooth Cayenne. Os resultados revelam a eficiência de bactérias diazotróficas na promoção do crescimento de abacaxizeiros.

Effects of Three Commercially Available Plant Growth Regulators and One Plant Growth Enhancer on Pepper (Capsicum annuumL.) Yield and Pigment Content

ABSTRACT Commercially available plant growth regulators (PGR) and plant growth enhancers (PGE) may be used to increase crop productivity and improve fertilizer and water use efficiency. Little independent field-scale research has been conducted concerning the benefit of these materials in actual production systems. This study was initiated to determine the efficacy of foliar PGR and PGE application in the production of paprika and cayenne cultivars of pepper (Capsicum annuum L.). Three PGRs and one PGE were foliarly applied to several production pepper fields in the Pecos River valley of southeastern New Mexico during the 1997 and 1998 growing seasons. The Reagan loam (fine-silty, mixed, superactive thermic Ustic Haplocalcid) soils were furrow irrigated with artesian groundwater, and individual replicated treatment blocks were a minimum 0.5 ha in size. All peppers were hand harvested. The paprika peppers were dried to constant weight, yields were determined, and paprika pigment extracts were analyzed spec...

Avaliação por RAPD de plantas de abacaxizeiro cultivar Smooth Cayenne derivadas do seccionamento do talo e cultura de tecidos

Foram coletadas, em área comercial da fazenda Córrego dos Bois, município de Canápolis -- MG, plantas de abacaxizeiro cultivar Smooth Cayenne, para serem avaliadas quanto à propagação pelo método do seccionamento do talo e cultura de tecidos, bem como análise por RAPD das mudas decorrentes destes dois processos de propagação. A propagação pelo seccionamento do talo foi eficiente na produção de mudas, tanto em quantidade como em qualidade, em um curto espaço de tempo, além de apresentar a mesma característica genotípica (análise por RAPD) das plantas-matrizes de origem. Já no processo de produção de mudas por cultura de tecidos, não foi obtida uma quantidade suficiente de mudas que comprovasse a utilização de uma metodologia mais sofisticada. Além da perda por contaminação em laboratório de 70% do material em estudo, foi necessária a utilização de um longo período, aproximadamente 18 meses, para a obtenção das mudas. Na análise por RAPD das plantas decorrentes deste processo de propagação, foram observados padrões de bandas diferentes em algumas amostras, as quais podem estar relacionadas com uma possível variação somaclonal.

Seed Leakage Does Not Contribute to Thermoinhibition in Jalapeno and Cayenne Cultivars

Chile (Capsicum annuum L.) seeds sown in July for fall transplants in the greenhouse often yield poor stands due to thermoinhibition. To determine cultivar response to high temperature, five jalapeno cultivars and one cayenne cultivar used commercially in Florida and New Mexico were tested. Two seedlots of `Cayenne, Large Red Thick', `Ole', `Jalapeno M', `Mitla', and `Tam Veracruz', and one seedlot of `Ebano' were evaluated on a thermogradient table at a temperature range of 20, 25, 30, 35, and 40°C. Percent germination, mean daily germination, and germination performance index were calculated. Additional seeds were soaked for 24 hours at 25, 30, 35, and 40°C. The exudate was then measured for electrical conductivity and glucose equivalents as an indication of seed leakage. All cultivars exhibited thermoinhibition, but the critical temperature of onset varied among cultivars. `Ebano' had the highest germination performance index across all temperatures among the six cultivars. At 40°C, however, no cultivar exceeded 4.0% germination. There was significant variation in germination performance between seedlots of some cultivars. The electrical conductivity and the number of glucose equivalents leached from the seed varied among cultivars, but did not correlate with decreased germination. Thermoinhibition in chile is probably due to factors other than those associated with membrane leakage.

Freezing Rate and Frozen Storage Effects on Color and Sensory Characteristics of Pineapple Fruit Slices

ABSTRACTThis study was carried out to evaluate the influence of freezing process (cold room –18°C and air‐blast freezer –50°C) and frozen storage (–18°C for 0 to 12 mo) on color and sensory quality of pineapple fruit slices (Smooth Cayenne and Red Spanish cultivars). L, –a and +b color parameters showed differences (P ≦ 0.05) with cultivar, but not with freezing rate. No differences (P ≥ 0.05) were found in sensory analysis (color and appearance) between the cultivars, frozen at different rates, compared to fresh product, or after 1 yr frozen storage. The two cultivars are suitable for freezing.

Effect of freezing rate and frozen storage on the texture and sensory analysis of two pineapple fruit cultivars

The effects of freezing rate (in a cold room at −18°C and in an air-blast freezer at −50°C) and frozen storage (at −18°C for 0–12 months) on texture and the sensory quality of pineapple fruit slices of Smooth Cayenne and Red Spanish cultivars were examined. The texture of pineapple fruit slices was evaluated by sensory and instrumental measurements. Sensory texture was highly (P≤0.05) and positively correlated with overall fruit acceptability and appearance and negatively correlated with flavour in the two cultivars studied. Sensory analysis showed no significant differences (P≤0.05) in the appearance, colour, odour, texture, flavour and overall acceptability between the two varieties studied when frozen at different rates, as compared to the fresh product and after 1 year of frozen storage at −18°C. The two cultivars are suitable for freezing.

Pineapple fruit: morphological characteristics, chemical composition and sensory analysis of red Spanish and Smooth Cayenne cultivars

Some physical (weight, size, shape, texture and colour), physico-chemical (pH, titratable acidity and soluble solids), chemical (soluble sugars and organic acids) and biochemical (total dietary fibre, peroxidase activity and soluble protein) characteristics and sensorial attributes (appearance, flavour, odour, colour, firmness and acceptability) of pineapple ( Ananas comosus L.) fruit were studied, in order to assess nutritional properties and consumer acceptability of the local Red Spanish and imported Smooth Cayenne cultivars. Significant differences ( P≤0.05) were found between size, shape and colour of the cultivars, and also between other objective (lightness, green colour, total acidity, soluble solids, total dietary fibre, peroxidase activity, fructose and glucose) and subjective (colour) measurements. Values of texture, fibre content and soluble solids to acid ratio were lower in the Red Spanish cultivar, while peroxidase activity and soluble protein were higher. Taste panelists preferred the appearance, colour and firmness of the Red Spanish pineapple slices.
