Solanum Lycopersicum L

Researches were conducted in 2019-2020 in the department of closed artificial agroecosystems for plant growing on the basis of Federal State Budgetary Scientific Institution “Federal Scientific Agroengineering Center VIM”, Moscow. The object of the study was the seeds of tomatoes Solanum lycopersicum L. The aim of the research was to study the effect of a biostimulant (succinic acid) on biological characteristics and productivity of Solanum lycopersicum L. grown in the substrate hydroponics of a climatic chamber. As a result of conducted researches, there was identified the most effective method of using succinic acid as a biostimulator – inoculation of seeds, which contributed to an increase in yield with a significant rise in relation to the control – 64.1%. The average fruit weight in this variant was 114.1 g, which exceeds the control by 37.0%. The complex application of the biostimulator provided an increase in the average fruit weight in 18.6%, the addition of hydroponics to the nutrient solution is 4.1%.

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.

Post Stress

Salinity toxicity and the post-stress restorative process were examined to identify the salt tolerance mechanism in tomato, with a focus on the antioxidant defense and glyoxalase systems. Hydroponically grown 15 day-old tomato plants (Solanum lycopersicum L. cv. Pusa Ruby) were treated with 150 and 250 mM NaCl for 4 days and subsequently grown in nutrient solution for a further 2 days to observe the post-stress responses. Under saline conditions, plants showed osmotic stress responses that included low leaf relative water content and high proline content. Salinity induced oxidative stress by the over-accumulation of reactive oxygen species (H2O2 and O2•−) and methylglyoxal. Salinity also impaired the non-enzymatic and enzymatic components of the antioxidant defense system. On the other hand, excessive Na+ uptake induced ionic stress which resulted in a lower content of other minerals (K+, Ca2+, and Mg2+), and a reduction in photosynthetic pigment synthesis and plant growth. After 2 days in the normal nutrient solution, the plants showed improvements in antioxidant and glyoxalase system activities, followed by improvements in plant growth, water balance, and chlorophyll synthesis. The antioxidant and glyoxalase systems worked in concert to scavenge toxic reactive oxygen species (ROS), thereby reducing lipid peroxidation and membrane damage. Taken together, these findings indicate that tomato plants can tolerate salinity and show rapid post-stress recovery by enhancement of their antioxidant defense and glyoxalase systems.

Management Techniques

An experiment was conducted to identify suitable production management techniques for tomato (Solanum lycopersicum L.) cultivation during late winter-pre monsoon season in plains of Nepal. For this, organic mulches (rice straw, dried grass, and rice husk) were compared with SN (shade net) and no-mulch (bare field) condition for tomato yield in 2018 and 2019. The pooled analysis of all observed morphological and yield traits were performed and they differed significantly. Rice husk significantly affected number of fruits per inflorescence though number of inflorescence per plant and flowers per inflorescence were similar among organic mulches. The highest fruit yield per plant (4.44 kg plant-1) was obtained with rice husk, the other mulches and SN were at par but the lowest yield (2.75 kg plant-1) was obtained with no-mulch. Similarly, rice husk mulch contributed to the highest number of fruits per inflorescence (5.22), highest fruit weight (46.58 g) and diameter (4.99 cm).Fruit yield positively and significantly associated with fruit per inflorescence(0.78***), fruit diameter (0.65***) and an average fruit weight (0.56***).Organic mulches significantly (p=0.05) contributed to higher yield (86.01 t ha-1) over SN (76.55 t ha-1).Higher values for total soluble solid, Vitamin C and fruit firmness were observed under rice husk mulching. The result of the present study found rice husk mulching as better option for tomato production as compared to SN and no-mulch condition.

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.

The objective of this study was to evaluate the response of three levels of electrical conductivity (2.0, 2.5 and 3.0 dS m-1) of Steiner’s nutrient solution on the yield, physicochemical quality, and antioxidant capacity of fruits from seven tomato genotypes and wild types of tomato (kidney selections). The yield, number of fruits per cluster (NFPC), average fresh fruit weight (AFWF), color, firmness, total soluble solids (TSS), total titratable acidity (TTA), vitamin C (VC), total phenols (TP), lycopene (LY) and antioxidant capacity (AC). The use of 2.5 and 3.0 dS m-1 increased the hue angle (49.05°) and TTA (0.35 and 0.36% citric acid). Among genotypes, L-51H and L-76H showed better performance (16.80 and 16.91 kg m-2, respectively), where L-28 stood out for its values of TSS, TTA, VC, TP and AC. Regarding the wild genotypes, the EC modification did not increase the yield; however, the use of 3.0 dS m-1 allowed the best results among the wild selections were SS3 (yield, AFWF and LY) and SS5 (NFPC, VC, TP and AC). The modification of the EC did not affect the yield, however, if it affected the physicochemical quality and antioxidant capacity of the analyzed materials.

Investigated the effect of different forms of training system the yield of tomatoes in greenhouses. The study involved the genetic forms of tomatoes with one, two and three trees. The influence of training system on the number of fruits per plant, fruit weight, fruit yield per plant and fruit yield per m2. The highest average yield per plant was achieved by growing tomatoes in the three trees, planting a tree in the form given by the average large fruit, and the highest number of fruits per plant was obtained with the training system with three trees, and the lowest in the training system on a tree. When growing on a tree reaches maturity at the earliest, and larger fruits, and the growing maturation of the two trees is a little later, the fruits are slightly smaller, but higher total yield of tomatoes. Growth on three trees achieved the highest yield, but the fruit is considerably smaller, which reduces their market value.

Estimates of heterosis for F1 hybrids over mid and better parent were computed for traits that showed significant differences between genotypes on analysis of variance. Heterosis for yield components and yield was studied using 8x8 half diallel cross in tomato (Solanum lycopersicum L.). The heterosis for yield was generally accompanied by heterosis for yield components. Heterosis for marketable fruit yield per plant ranged from (-63.4%) (P3xP8) to (33.8%) (P6xP8) and (-62.5%) (P3xP8) to (52.6%) (P5xP7), for mid parent and better parent respectively. Significant heterosis over better and mid-parent was observed for all the traits.  Best parent and Mid-parent heterosis (MPH) was highest  and in desirable direction for number of marketable fruit per plant  (29.3%; 29.2%)  in crosses ( P3xP6 for both ) and pericarp thickness  (46.3%; 57.6%) in crosses (P2xP6 and P4xP8), number of fruit cluster per plant (32.8%; 35.9%) in cross (P3xP6 for both), individual fruit weight (36.1%; 41.2%) in cross (P2xP8, P3xP5) and fruit diameter (28.4%; 28.3%) in cross (P3xP5; P2xP6), fruit length (23.07%; 20.4%)  in cross (P2xP6 for both). Out of 28 F1 crosses, positive and desirable heterosis by 10 crosses over better parent and 17 crosses over mid-parent were observed for total fruit density in tomato. An important heterosis both in heterobeltiosis and mid-parent was recorded in marketable fruit yield in ton per hectare. From all the crosses, seven crosses revealed positive from which three crosses are the most important P2xP7 (31%),  P3xP5 (20%) and P3xP6 (54%) in better parent heterosis. Similarly for mid-parent heterosis, only ten crosses out of 28 reveled positive while the rest 18 crosses showed the undesirable direction for marketable fruit yield indicating majority of the hybrids exhibited unfavorable heterotic response and only a few hybrids could be considered for selection.

Plant density and fertilization are key practices for improving the fruit quality and yield of vegetables grown in greenhouses. The experiment was performed to investigate the effects of density and fertilization on the fruit yield and quality, economic efficiency of Solanum lycopersicum L. at Duc Trong district of Lam Dong province. The density (50,000; 33,000; 25.000 plants ha-1) and the fertilizer rates (240N – 100P2O5 – 275K2O; 300N – 125P2O5 – 344K2O; 360N – 150P2O5 – 413K2O kg and 420N – 175P2O5 – 482K2O kg ha-1) were studied in a completely randomised split plot design with three blocks. The fertilizer rate (420N – 175P2O5 – 482K2O kg ha-1) was produced the highest height (562.39 cm), fruit setting rate (69.87%), number of fruit per plant (95.65 fruits), average fruit weight (106.37 g), fruit yield (441.11 tons ha-1) and marketable fruit yield (204.31 tons ha-1). The density (25,000 plants ha-1) gave the highest fruit setting rate (75.35%), number of fruit per plant (94.84 fruits), average fruit weight (113.24 g), individual fruit yield (10.02 kg per plant) and fruit yield (501.17 tons ha-1). The combination of density (25,000 plants ha-1) and fertilizer rate (420N – 175P2O5 – 482K2O kg ha-1) have the highest fruit yield (613.5 tons ha-1), marketable fruit yield (223.91 tons ha-1) and rate of return (2.44). In addition, this combination was the best density and fertilizer level management strategy for greenhouse-grown Lahay 334 tomato cultivar in Lam Dong province, Vietnam.

Intensive tomato (Solanum lycopersicum L.) production in coastal areas of Sinaloa is exposed to significant amounts of Cl and Na deposited by sea breezes and irrigation water, which affects the yield of this vegetable. The aim of this study was to evaluate three percentage ratios of Cl-/anions (25/100, 50/100 and 75/100) and three percentage ratios of Na+/cations (25/100, 50/100 and 75/100) in the nutrient solution on mineral composition, dry matter production and yield of tomato. The experimental design was completely randomized with a 32 factorial arrangement and four replications. Analysis of variance and mean comparisons were performed (Tukey, P ≤ 0.05). Cl and Na concentrations in tomato leaves, stems and fruits increased significantly with increasing ratios of Cl-/anions and Na+/cations in the nutrient solution. The 75/100 Cl-/anions ratio reduced (P ≤ 0.05) the Ca concentration in leaves, while the 75/100 Na+/cations ratio decreased (P ≤ 0.05) K concentrations in leaves and stems. Both ratios reduced aerial dry biomass (48 and 25.8 %, respectively) and tomato yield (50.8 and 45.7 %, respectively). The results indicate that tomato plants grown with the 75/100 percentage ratio of Cl-/anions or the 75/100 percentage ratio of Na+/ cations absorb excessive amounts of Cl or Na, which causes ionic imbalance (especially of K+ and Ca2+) and affects dry matter production and yield.
