Comparative assessment of FSM and MPSIAC models in quantifying soil sedimentation rates in the semi-humid and alpine regions of northern Iran.

Soil erosion and sediment yield is a global problem that increasingly contributes to soil degradation. Although erosion analysis requires the availability of erosion and sedimentation data, the lack of sediment monitoring stations and the resulting limitations in collecting sediment measurements have necessitated the use of experimental models in many areas. The present study aimed to compare Factorial Scoring Model (FSM) and Modified Pacific South-West Inter-Agency Committee (MPSIAC) model for estimating erosion in the Mazdaran Basin (Firoozkuh, Iran). For this purpose, the required maps were prepared for both models, and the sediment rate was estimated using the two models to compare their efficiency using the corresponding maximum error (ME) and coefficient of determination (R2) values. The results showed that considering sediment based on the FSM model, the studied catchment consisted of regions with a high and very high sediment yield, while the MPSIAC model identified regions with low, medium, and high sediment yield. With an R2 value of 0.62 and an ME value of 2.24, the MPSIAC model provided more accurate estimates of the sediment yield in the studied area. Using the MPSIAC model, sediment yield was 6687.86 tons per year or the equivalent of 2.64 tons/ha per year.

Carbon quantum dots from carbohydrate-rich residue of birch obtained following lignin-first strategy

Carbon quantum dots (CQDs) were successfully synthesized from carbohydrate-rich residue of birch obtained following the lignin-first strategy. The optical and physicochemical properties of the CQDs were studied, along with their potential for photocatalytic pollutant degradation. By combining solvothermal and chemical oxidation methods, the product yield of CQDs from carbohydrate-rich residue reached 8.1 wt%. Doping nitrogen enhances the graphitization of CQDs and introduces abundant amino groups to the surface, thereby boosted the quantum yield significantly from 8.9 % to 18.7 %-19.3 %. Nitrogen-doped CQDs exhibited efficient photocatalytic degradation of methylene blue, reaching 37 % within 60 min, with a kinetic degradation rate of 0.00725 min−1. This study demonstrates that carbohydrate-rich residue obtained from lignin-first strategy are ideal precursors for synthesizing CQD with high mass yield and quantum yield by combining solvothermal treatment and chemical oxidation methods, offering a novel approach for the utilization of whole biomass components following the lignin-first strategy.

Constructing new bonds to carbon in dihydroquinazolines via hypervalent iodine(III)-mediated C(sp3)-C(sp3) bond functionalization.

A hypervalent iodine(III)-mediated C(sp3)-C(sp3) bond functionalization reaction for the formation of C-C, C-P, and C-H bonds in dihydroquinazolines has been developed. This one-pot method involves successive oxidation of dihydroquinazoline substrates, mesolytic cleavage of a tert-butyl substituent, and bond formation to a variety of nucleophiles in moderate to high yields.

Reverse Intersystem Crossing Boosting Sensitizer for Ultra-High Efficiency Blue Organic Light-Emitting Diode.

In designing thermally activated delayed fluorescence (TADF) emitters, a high reverse intersystem crossing (RISC) rate with a high photoluminescence quantum yield is essential. Herein, two blue TADF molecules, 2',5'-di(9H-carbazol-9-yl)-3',6'-bis(3,6-ditert-butyl-9H-carbazol-9-yl)-[1,1':4',1″-terphenyl]-4,4″-dicarbonitrile (CzTCzPhBN) and 2',5'-bis(3,6-ditert-butyl-9H-carbazol-9-yl)-3',6'-bis(3,6-diphenyl-9H-carbazol-9-yl)-[1,1':4',1″-terphenyl]-4,4″-dicarbonitrile (PhCzTCzPhBN) with a high RISC rate, were developed through donor engineering. CzTCzPhBN and PhCzTCzPhBN showed a high RISC rate of 4.00 × 105 and 16.62 × 105 s-1, respectively, with a high photoluminescence quantum yield of 80.1 and 84.9%, which resulted in high external quantum efficiency of 27.0 and 27.8% with color coordinates (0.148, 0.170) and (0.150, 0.230) in blue TADF organic light-emitting diodes, respectively. The high RISC rate and device efficiency inspired two TADF molecules to be used as sensitizers in hyperfluorescence devices. The hyperfluorescence devices showed ultra-high external quantum efficiency of 30.7 and 36.4% with color coordinates (0.125, 0.164) and (0.127, 0.193), respectively.

The improved purification technique for isolation of the novel CGTase from the alkaliphilc strain Caldalkalibacillus mannanilyticus IB-OR17-B1

Cyclodextrin-glucanotransferase (CGTase, EC 2.4.1.19) is a multifunctional enzyme that catalyzes many enzymatic reactions including cyclization, binding, disproportionation and hydrolysis reactions, playing an important role in the enzymatic synthesis of compounds that are widely used in agriculture, pharmaceuticals, food, chemical and biotechnology industries. The present research is aimed to optimize the purification protocol for the extracellular CGTase of alkaliphilc bacterial strain Caldalkalibacillus mannanilyticus IB-OR17-B1 guaranteeing the enzyme homogeneity and its high yield. The improved combination of ultrafiltration and corn-starch (5% w/v) affinity sorption techniques resulted to mild and rapid isolation of electrophoritically homogenic enzyme at 18 × increase of its specific activity and yield 56%. The developed two-step procedure instead the practiced tree-step one using commonly ion-exchange chromatography as final purification technique highly contributes in advance of cost-effectiveness for industrial production and isolation of valuable CGTases.

Synthesis of Quarternized Chitosans and Their Potential Applications in the Solubility Enhancement of Indomethacin by Solid Dispersion.

This study was designed to synthesize quarternized chitosans (Q-CS) and explore their potential application in aqueous solubility enhancement of indomethacin (IND), a BCS class-II drug.Three different Q-CS; N,N,N-trimethyl chitosan chloride (TMC), N-(4-N'-methylpyridinylmethyl) chitosan chloride (mPyCS), and N-(4-N',N',N'-trimethylaminobenzyl) chitosan chloride (TmBzCS) were synthesized and characterized through various spectroscopic analysis. Q-CS-based solid-dispersion (SD) composites of IND (Q-CS-IND) were prepared using the spray-drying methodand characterized through Fourier transform infrared (FTIR), scanning electron microscopy (SEM), differential-scanning calorimetry (DSC), and powder X-ray diffraction (P-XRD). The solubility and dissolution profiles of SD-composites of IND were evaluated and compared with physical mixtures (PM). The IND contents were quantified and validated in the composites using UV-Vis spectrophotometer.FTIR and NMR analysis showed the successful preparation of Q-CS. TMC was found with the highest yield (55.13%) and mPyCS with the highest degree of quaternization (DQ) (63.37%). FT-IR analysisof IND-Q-CS composites demonstrated chemical interaction between carbonyl moieties of IND with functional groups of Q-CS. DSC and PXRD analyses demonstrated the transformation of IND in SD compositesfrom crystalline to an amorphous form. All the IND-Q-CS composites were observed with a significant increase in the solubility and dissolution rate of the drug (1996.0µg/min) compared to PM (1306.8µg/min), which is higher than pure IND (791.6µg/min). The contents of IND in TMC, mPyCS, and TmBzCS composites were 97.69-99.92%, 97.66-100.25%, and 97.18-100.11% respectively.Overall, the findings encourage the applications of Q-CS derivatives for increasing IND water solubility and warrant further in vivo biological profiling of IND composites.

Self-assembled dipeptide confined in covalent organic polymers for fluorescence sensing of tryptamine in fermented meat products.

Diphenylalanine(FF)-Zn self-assembly (FS) confined in covalent organic polymers (FS@COPs) with efficient fluorescence was synthesizedfor fluorescence sensing of biogenic amines, which was one of the most important indicators for monitoring food freshness. FS@COPs combined excellent biodegradability of self-assembled dipeptide with chemical stability, porosity and targeted site recognition of COPs. With an optimal excitation wavelength of 360 nm and an optimal emission wavelength of 450 nm, FS@COPs could be used as fluorescence probes to rapidly visualize and highly sensitive determination of tryptamine (Try) within 15 min, and the linear range was from 40 to 900 μg L-1 with a detection limit of 63.08 μg kg-1. Importantly, the FS@COPs showed a high fluorescence quantum yield of 11.28%, and good stability, solubility, and selectivity, which could successfully achieve the rapid, accurate and highly sensitive identification of Try. Furthermore, we revealed the mechanism of FS@COPs for fluorescence sensing of targets. The FS@COPs system was applied to the fluorescence sensing of Try in real samples and showed satisfactory accuracy of 93.02%-105.25%.

Waste heat-driven water generator with optimized multi-cycle strategy for high water yield

Water scarcity and energy crisis have recently become two severe global problems. Low-grade waste heat, a substantial byproduct of energy consumption, promises to provide safe water by driving sorption-based atmospheric water harvesting (SAWH) device. Herein, a low-grade waste heat-driven atmospheric water generator (LWG) is constructed with rapid kinetics at the system level. Solely in 3 h, the device obtains 1.766 g g−1 of water productivity and up to 98 % of water recovery ratio driven by 120 °C of waste heat. Further, an optimized multi-cycle operation strategy is proposed to guide LWG's daily water harvesting, enabling it to predictably obtain over 15 kg m−2 day−1 water productivity by maximizing systemic sorption and desorption-condensation rates. The strategy not only is widely suitable for all SAWH devices, but also provides a universal optimization guideline for sorption-based dehumidification, thermal storage, and electric thermal management.

Enhancing Localized Electron Density over Pd1.4Cu Decorated Oxygen Defective TiO2-x Nanoarray for Electrocatalytic Nitrite Reduction to Ammonia.

Electrocatalytic nitrite (NO2 -) reduction to ammonia (NH3) is a promising method for reducing pollution and aiding industrial production. However, progress is limited by the lack of efficient selective catalysts and ambiguous catalytic mechanisms. This study explores the loading of PdCu alloy onto oxygen defective TiO2-x, resulting in a significant increase in NH3 yield (from 70.6 to 366.4µmolcm-2h-1 at -0.6V vs reversible hydrogen electrode) by modulating localized electron density. In situ and operando studies illustrate that the reduction of NO2 - to NH3 involves gradual deoxygenation and hydrogenation. The process also demonstrated excellent selectivity and stability, with long-term durability in cycling and 50h stability tests. Density functional theory (DFT) calculations elucidate that the introduction of PdCu alloys further amplified electron density at oxygen vacancies (Ovs). Additionally, the Ti─O bond is strengthened as the d-band center of the Ti 3d rising after PdCu loading, facilitating the adsorption and activation of *NO2. Moreover, the presence of Ovs and PdCu alloy lowers the energy barriers for deoxygenation and hydrogenation, leading to high yield and selectivity of NH3. This insight of controlling localized electron density offers valuable insights for advancing sustainable NH3 synthesis methods.

Mutation Breeding of Monascus to Produce a High Yield of Orange Pigment and Low Citrinin Content Using the ARTP Method

Monascus is a filamentous fungus with a long history of application in China, which can produce a variety of secondary metabolites, including Monascus red pigments, Monascus orange pigments, Monascus yellow pigments, and citrinin. There is widespread attention being paid to natural pigments because of their safety. Among the many natural pigments, orange pigment has a wide range of applications because of its unique color, but current production levels in the orange pigment industry are limited to a certain extent due to the insufficiently wide range of sources and low production. In this study, the ARTP mutation was used to obtain a strain with high-yield orange pigment and low citrinin. The strain RS7 was obtained through two-step mutagenesis, and all three pigments were improved to different degrees. The color value of orange pigment was elevated from the original 108 U/mL to 180 U/mL, an increase of 66.7% compared to the original strain, and the citrinin content was reduced by 69%. The result of microscopic morphology showed that RS7 has more wrinkles and is more convex than the R1 strain, but there was little change between the two strains. Therefore, the ARTP mutation influenced the growth and the biosynthesis of pigments in Monascus. In addition, the conditions of ultrasonic extraction of Monascus pigments were optimized using the response surface, and the separation of pigments was achieved with the method of thin-layer chromatography. Pigment stability results showed that the temperature had no significant effect on orange pigment, while tea polyphenol could improve its stability. This study generated a strain with high-yielding orange pigment and could lay a foundation for the future application of Monascus orange pigment in the food industry.

Catalytic enantioselective intramolecular hydroamination of alkenes using chiral aprotic cyclic urea ligand on manganese (II)

Asymmetric catalysis for enantioselective intramolecular hydroamination of alkenes is a critical method in the construction of enantioenriched nitrogen-containing rings, often prevalent in biologically active compounds and natural products. Herein, we demonstrate a facile enantioselective intramolecular hydroamination of alkenes for the synthesis of chiral pyrrolidine, piperidine, and indoline moieties, using a manganese (II) chiral aprotic cyclic urea catalyst. The cyclic ligand hinders the inversion of the N atom of the urea and effectively discriminate between the enantiomers of substrates. High-resolution mass spectrometry, deuterium labeling experiments, and molecular orbital energy analysis clearly reveal the intermediates and mechanism of the transformation. As a key step, oxygen coordination by chiral aprotic urea presents a robust control over the asymmetric intra-HA reaction through the involvement of a convergent assembly of two vital intermediates (Mn-N and C-Mn-Br), providing access to chiral cyclic amine systems in high yields with excellent enantioselectivity.

The use of automatic belt feeders in a Penaeus vannamei pilot scale super-intensive nursery and grow-out with biofloc system

This study aimed to evaluate the effect of using automatic belt feeders (BF) on water quality, growth of Penaeus vannamei, and partial budget in super-intensive pilot scale systems with biofloc technology. A nursery phase (2300 shrimp m−2) and a grow-out phase (400 shrimp m−2) were carried out with the following feeding management strategies, all with three repetitions: T1: by hand, T2: by hand + BF12h; T3: BF24h. In the nursery, a spike in total ammonia concentration was observed in the first weeks of the trial in treatment T1, possibly due to nutrients from uneaten feed. Nitrite was higher in T1 treatment than in T2 and T3. Nitrate was lower in the treatment T1 than in T2 and T3. At the grow-out trial, nitrite was higher in treatment T1 than in T2 and T3. These results indicated a slower nitrification process in T1 and more efficient in treatments where automatic feeders were used since an accumulation of nitrate was observed throughout the trials and low concentrations of nitrite were observed both in the nursery and the grow-out. In the nursery and the grow-out, the T3 treatment had a higher final weight and a lower feed conversion ratio. Furthermore, the T3 treatment had a higher yield than the T1 treatment. Treatment T3 had the highest net benefit/cost, considering the entire production cycle (nursery and grow-out). Our results strongly indicate that using automatic belt feeders allows an improvement in water quality, promotes shrimp growth, improves yield, reduces feed use, and improves the net benefits in P. vannamei super-intensive nursery and grow-out with biofloc systems.

Comparative effectiveness of interventions for cancer treatment–related cognitive impairment in adult cancer survivors: protocol for a systematic review

BackgroundCancer treatment–related cognitive impairment (CTRCI) can substantially reduce the quality of life of cancer survivors. Many treatments of CTRCI have been evaluated in randomized controlled trials (RCTs), including psychological interventions, pharmacologic interventions, and other therapies. There is a pressing need to establish the benefits and harms of previously studied CTRCI treatments. The proposed systematic review and network meta-analyses will assess the relative efficacy and safety of competing interventions for the management of CTRCI.MethodsIn consultation with the review team, an experienced medical information specialist will draft electronic search strategies for MEDLINE®, Embase, CINAHL, PsycINFO, and the Cochrane Trials Registry. We will seek RCTs of interventions for the treatment of CTRCI in adults with any cancer, except cancers/metastases of the central nervous system. Due to the anticipated high search yields, dual independent screening of citations will be expedited by use of an artificial intelligence/machine learning tool. The co-primary outcomes of interest will be subjective and objective cognitive function. Secondary outcomes of interest will include measures of quality of life, mental and physical health symptoms, adherence to treatment, and harms (overall and treatment-related harms and harms associated with study withdrawal), where feasible, random-effects meta-analyses and network meta-analyses will be pursued. We will address the anticipated high clinical and methodological heterogeneity through meta-regressions, subgroup analyses, and/or sensitivity analyses.DiscussionThe proposed systematic review will deliver a robust comparative evaluation of the efficacy and safety of existing therapies for the management of CTRCI. These findings will inform clinical decisions, identify evidence gaps, and identify promising therapies for future evaluation in RCTs.

Ferrier Glycosylation Mediated by the TEMPO Oxoammonium Cation.

The TEMPO oxoammonium cation has been proven to be both an efficient oxidizing reagent and an electrophilic substrate frequently found in organic reactions. Here, we report that this versatile chemical reagent can also be used as an efficient promoter for C- and N-glycosylation reactions through a Ferrier rearrangement with moderate to high yields. This unprecedented reactivity is explained in terms of a Lewis acid activation of glycal by TEMPO+ forming a type of glycal-TEMPO+ mesomeric structure, which occurs through an extended vinylogous hyperconjugation toward the π*(O═N+) orbital [LP(O1) → π*(C1═C2), π*(C1═C2) → σ*(C3-O3), and LP(O6) → π*(O═N+)]. This enables the formation of the respective Ferrier glycosyl cation, which is trapped by various nucleophiles. The extended hyperconjugation (or double hyperconjugation) toward the π*(O═N+) orbital, which confers the Lewis acid character of the TEMPO cation, was supported by natural bond orbital analysis at the M06-2X/6-311+G** level of theory.

Three‐Component Allylic Alkylation Reaction of α‐Diazo Ketones with Water and Allyl Carbonates for Construction of Homoallylic Alcohols

AbstractA three‐component allylic alkylation reaction of α‐diazo ketones, water and allyl carbonate under the cooperative catalysis of Rh2(OAc)4, Pd2(dba)3 and Brønsted acid was disclosed. This method provides an expeditious access to α‐keto homoallylic alcohols in good to high yields. Controlled experiments support that the transformations proceed through cross‐interception of two active intermediates Pd‐allyl species and enol intermediates derived from oxonium ylides. Moreover, synthetic transformations of the generated products enable the creation of motifs enriched with dense functional groups, underscoring their potential as valuable building blocks.

The Contribution of Trichoderma viride and Metallothioneins in Enhancing the Seed Quality of Avena sativa L. in Cd-Contaminated Soil

Pollution of arable land with heavy metals is a worldwide problem. Cadmium (Cd) is a toxic metal that poses a severe threat to humans’ and animals’ health and lives. Plants can easily absorb Cd from the soil, and plant-based food is the main means of exposure to this hazardous element for humans and animals. Phytoremediation is a promising plant-based approach to removing heavy metals from the soil, and plant growth-promoting micro-organisms such as the fungi Trichoderma can enhance the ability of plants to accumulate metals. Inoculation of Avena sativa L. (oat) with Trichoderma viride enhances germination and seedling growth in the presence of Cd and, in this study, the growth of 6-month-old oat plants in Cd-contaminated soil was not increased by inoculation with T. viride, but a 1.7-fold increase in yield was observed. The content of Cd in oat shoots depended on the Cd content in the soil. Still, it was unaffected by the inoculation with T. viride. A. sativa metallothioneins (AsMTs) participate in plant–fungi interaction, however, their role in this study depended on MT type and Cd concentration. The inoculation of A. sativa with T. viride could be a promising approach to obtaining a high yield in Cd-contaminated soil without increasing the Cd content in the plant.

Antioxidant and Anti-Atherosclerosis Activities of Hydrolyzed Jellyfish Collagen and Its Conjugate with Black Jelly Mushroom Extract

Atherosclerosis, a noncommunicable disease caused by cholesterol plaque, can cause chronic diseases. The antiplatelet medicines used in its treatment can cause complications. Marine collagen peptides can be used as a natural atherosclerosis remedy. The present study investigated the preparation and characterization of hydrolyzed collagen (HC) from jellyfish and its conjugation with black jelly mushroom extract (BJME). Their cytotoxicity and ability to prevent cholesterol-induced endothelial cell injury were also examined. HC was prepared using Alcalase or papain hydrolysis (0.2–0.4 units/g of dry matter (DM)). Higher yield, degree of hydrolysis, and antioxidant activities (AAs) were found in the HC obtained from Alcalase, especially at 0.4 units/g DM (A-0.4), compared to other processes (p < 0.05). Thus, A-0.4 was further conjugated with BJME (1–4%, w/w of HC). The HC-2%BJME conjugate showed the highest surface hydrophobicity and AAs compared to other samples. The FTIR spectra and size distribution also confirmed the conjugation between HC and BJME. When EA.hy926 endothelial cells were treated with HC or HC-2%BJME (25–1000 µg/mL), HC-2%BJME had no cytotoxicity, whereas HC at 1000 µg/mL induced cytotoxicity (p < 0.05). Both samples also exhibited protective ability against cholesterol-induced apoptosis and VE-cadherin downregulation of cells. Therefore, HC and conjugate could be natural agents for preventing atherosclerosis.

Growth performance of eel fish (Anguilla bicolor) which are maintained in containers of different colors

Performance of Eel (Anguilla bicolor) maintened in containers of different colors. Growth is the main driver in increasing the profitability of aquaculture. In addition to maintenance management the color of the container is also a factor supporting the growth of eels. This study aims to determine the effect of the color of different rearing containers on the growth and appetite response of eel. The test fish used were elver stage eels with an average weight (129 ±131g). The method used is an experiment with two treatments they are grey and green. The test fish were placed in a container measuring 19x4 m2 and a water level of 1m with a stocking density of 1100 individuals each, 30 days of rearing. The variables observed were growth performance including SR (Survival Rate), ADG (Average Daily Growth), FCR (Food Conversion Ratio), SGR (Specific Growth Rate). The results obtained indicated that there was a significant difference in the average growth of fish reared in grey and green containers. Grey container treatment was proven to get higher yields with average final weight values (192.4 ± 4.5 g), FCR (1.01 ± 0.02), ADG (2.01g/day ± 0.06), SGR (1 .25%BW/day±0.02). Based on the results of the study it can be concluded that there is a significant difference in the growth of eels reared in ash and green containers. The color of the ash container proved to be better in supporting growth performance.Keywords: Elver; Green; Grey; Nocturnal

The Diagnostic Yield of Laboratory Tests in Chronic Constipation in Adults.

Chronic constipation is a common gastrointestinal complaint characterized by infrequent or difficult bowel movements, significantly affecting patients' quality of life. Laboratory markers offer potential diagnostic value in identifying physiological changes associated with chronic constipation, yet their effectiveness remains underexplored. The objective of this study was to evaluate the diagnostic value of various laboratory tests in identifying the underlying causes of chronic constipation among adults. A cross-sectional study was conducted at Kurdistan Private Hospital and Jeen Clinics in Duhok, Kurdistan, Iraq, from December 2022 to May 2024. A total of 132 patients meeting the Rome IV criteria for chronic constipation were included. Data collection involved demographic information, lifestyle factors, and laboratory tests, including complete blood count (CBC), thyroid stimulating hormone (TSH), serum calcium, serum potassium, serum glucose, serum creatinine, parathyroid hormone (PTH), and vitamin D levels. The study population consisted of 56 males (42.4%) and 76 females (57.6%) with a mean age of 46.5 years (SD=17 years) and a range of 18-81 years. Regular exercise was performed by only 56 (42.4%) patients, 85 (64.4%) patients were drinking less than 2 liters of water per day, and 108 (81.8%) were overweight or obese. Of the study population, hypothyroidism was detected in 27 (20.4%), hyperparathyroidism in 27 (20.4%), anemia in 58 (44%), leukocytosis in 24 (18.2%), renal impairment in 48 (36.4%), hypokalemia in four (3%), hyperkalemia in 12 (9.1%), hypocalcemia in 10 (7.6%), hypercalcemia in 12 (9.1%), impaired fasting glucose in 46 (34.8%), hyperglycemia in 21 (15.9%), and vitamin D deficiency in 80 (60.6%). Of the study population, 40 (30%) patients had normal laboratory investigations panel. In chronic constipation, laboratory tests have high diagnostic yield in adults and are essential for ruling out secondary causes of chronic constipation. Unhealthy lifestyles are prevalent in patients with chronic constipation.

CHARACTERIZATION OF NEWLY INTRODUCED POMEGRANATE VARIETIES

The paper is focused on examining and selecting morphometric indicators of leaves and flowers from genotypes within the collection of the pomegranate varieties. The research was carried out on 6 varieties of pomegranate plants, collected and introduced from diverse ecological and geographical regions. The objective was to collect, cultivate and assess the technological features of pomegranate varieties and forms. The morphometric characteristics of generative and vegetative organs from the “Malas” and “Kirmizi Gazyan” varieties were studied for the first time. Observation of pomegranate flower petals revealed that different sizes could be found in both long toothed (LT), middle toothed (MT) and short-toothed (ShT) flowers, suggesting petal size is not determined by flower type. The difference between the leaves of these two varieties was found to be insignificant. Flower diameter showed variability across all three types of flowers. The biological and economic significance of the newly developed form F-6-8 and the varieties “Malta”, “Oleg” and “Devachi” was also assessed. “F-6-8” and “Malta” are sweet varieties, while “Oleg” and “Devachi” are sweet and sour varieties. “Malta” was distinguished by its fruit weight (380.4 g), thin skin (2.5 g) and high juice yield (50.4%).
