Postharvest Loss

Tomato (Solanum Lycopersicum L. (or) Lycopersicon esculentum Mill.) is being a very nutritious and health protective food, are highly perishable nature. Its sensitivity to postharvest loss due to poor handling, diseases and physical injury limits its successful marketing. Therefore, simple technology is required to reduce the postharvest loss of this commodity. The use of edible coatings with bio-extracts appears to be a good alternative preservation technique to extend the mature tomato fruits. This study was, therefore, initiated to investigate the effect of using bio- extracts garlic bulba and capsicum incorporation with coating materials (maize starch and beeswax on physicochemical quality of tomato fruit stored at ambient conditions (temperature 15.5 to 20.2oC and relative humidity of 55.5 to 67.3%). The experiment was conducted using complete randomized design of two varieties (Fetane and Melkashola) and six treatments. The tomato fruits were coated by dipping into solution for 3 minutes. The treatments prepared were on coating solution of MGE( 9.5% maize starch with 0.5% garlic extract), MCE (9.5% maize starch with 0.5% capsicum extract), BCE (9.5% beewax mixed with 0.5% capsicum extract), BGE (9.5% beewax mixed with 0.5% garlic extract), 10% maize starch without bio-extract, 10% beewax without bio- extract and control. The treatment means were tested at significance level of P ≤ 0.05. The effectiveness of bio-extracts with coating materials on physicochemical quality of tomato fruits were evaluated at three days intervals for 30 days. There was a significance difference (P<0.05) between coated and uncoated fruits. All coatings delayed tomato ripening and improved the keeping quality parameters but best results were exhibited by 9.5% with 0.5% BCE followed by 9.5% with 0.5% MGE by maintaining the mature tomato fruit for 30 days. The study showed that the Fetane variety has maintained more quality attribute than Melkashola variety during storage.

Additive Gene

Nine traits of 11 cherry tomato (Solanum lycopersicum L.) var. cerasiforme (Dunal) A. Gray) inbred lines exhibited a wide range of genetic variability. High geno- and phenotypic coefficients of variation were obtained for individual fruit weight (68.16 and 74.23%, respectively) followed by number of fruits/plant (58.8 and 68.34%, respectively). High estimates of heritability, genetic advance and genotypic coefficient of variation for the traits of individual fruit weight, number of fruits and clusters/plant were controlled by additive gene action indicating the possibility of selection to improve these characters. Fruit yield/plant showed low heritability along with low genetic advance and did not show significant and positive correlation with the remaining characters. It indicates that improvement of high yield through selection is difficult, rather hybridization can be effective for improving the fruit yield/plant. Among the lines, CH154 produced the highest number of fruits/plant (291) and highest fruit yield (1.89 kg/plant and 63.4 t/ha) and can be selected for cultivation under Bangladesh condition.

Nutrient Solutions

Tomato (Solanum lycopersicum L.) is an important vegetable in the country which is consumed both raw and as processed product. This study aimed to evaluate the growth, yield, postharvest qualities and profitability of aquaponically grown tomato supplemented with different nutrient solutions. The study was laid out in Randomized Complete Block Design with 8 treatments replicated 3 times. Tomato fruits were first harvested 60 days after transplanting with 100 percent survival rate. Early flowering of tomato plant was observed when applied with VSU liquid nutrient formulation (VSU-LNF) with node number ranging from 13.33-14.00 bearing the first flower. Growth parameters such as plant height, number of lateral shoot, root length and fruit size are stimulated by the application of VSU liquid nutrient formulation and in combination with ferments. This also resulted to high number and weight of marketable fruit in tomato plant. Carotenoid and chlorophyll contents of the fruits were higher in aquaponically grown tomato supplemented with fermented kuhol (Pomacea canaliculata L.). Free radical scavenging activity was found highest in the fruit of tomato grown in aquaponic system supplemented with combined VSU liquid nutrient formulation with fermented malunggay (Moringa olifera). However, vitamin Cand sugar content of tomato fruits were found highest when supplemented with combine VSU liquid nutrient formulation and fermented kuhol. No significant differences were obtained on firmness, percent weight loss, respiration rate at 2 and 4 weeks after storage, titratable acidity, fruit nitrogen, pH of fruit, oxidation reduction potential, electrical conductivity and total dissolved solids. On the other hand, higher moisture content of the tomato fruits were observed with the application of VSU liquid nutrient formulation and in combination with ferments. Therefore, high yield was produced with the application of VSU liquid nutrient formulation which resulted to higher net return. Aquaponically grown tomato supplemented with VSU-LNF produced lesser yield but with considerable net return.

Genotypic Coefficient Of Variation

Twenty-nine genotypes of cherry tomato (Solanum lycopersicum L. var. cerasiforme) were evaluated for their genetic variability and heritability. A wide range of genetic variability was observed for twenty traits of cherry tomato genotypes. The analysis of variance was significant for all the characters indicating genetic variability in the genotypes under the study except number of locules per fruit. The highest phenotypic and genotypic coefficient of variation were observed for lycopene (43.12, 42.94), total carotenoids (42.82, 42.51), average fruit weight (42.52, 42.50), fruit yield per hectare (42.29, 42.24). In general Phenotypic Coefficient of Variation (PCV) was marginally higher than the corresponding Genotypic Coefficient of Variation (GCV) indicating the less influence of environment in the expression of traits under study. High heritability coupled with high genetic advance as percentage of mean was observed for almost all characters indicating that most of the traits studied were mainly controlled by additive gene effect and thus selection may be effective.

Cherry Tomatoes

Tomato (Solanum lycopersicum L.) is a well-known plant that belongs to the Solanaceae family. It is a widely consumed vegetable, either fresh or industrially processed. The aim of this study was to characterize and compare the morphology, main physicochemical parameters, volatile composition, and sensory quality of 8 cherry tomato cultivars: 4 pear cherry tomatoes (Angelle, Seychelles, Santyplum, and Dolcetini) and 4 round cherry tomatoes (Katalina, Sweet star, C-95, and Karelya) to be able to replace the most popular ones in markets (Angelle and Katalina). Morphological parameters had significant differences among cultivars, while in terms of total soluble solids and titratable acidity, Dolcetini could be an interesting substitute of Angelle in pear cherry cultivars, while in round ones C-95 would be the closest one. Regarding sugars, Santyplum was probably the cultivar which could be placed into a similar place to Angelle, while in round ones, C-95 was probably the cultivar closest to Katalina. Santyplum, Seychelles (pear type), and C-95 (round type) are likely to be the most interesting cherry cultivars in providing a real alternative to the most cultivated ones, in terms of volatile profile and concentration of the main volatile compounds. Descriptive sensory analysis revealed that Seychelles cultivar in 9 of the 15 attributes under study could be considered as the most similar cultivar to replace Angelle, while in round types no clear and direct relationship was found with any cultivar. Finally, consumers reported similar values for Angelle and Seychelles pear type cultivars, while round ones did not show significant differences. In summary, it can be stated that Seychelles and C-95 are the best alternatives of pear and round cherry cultivars, respectively, as compared to the reference cultivars, Angelle and Katalina.
