In vitro evaluation of tomato (Lycopersicon esculentum Mill.), chilli (Capsicum annum L.), cucumber (Cucumis sativus L.) and Bhendi (Abelmoschus esculentus L.) for salinity stress

Abstract

Salinity is one of the most important abiotic stresses limiting yield potential. Salinity is even more harmful to seed germination and seedling development. The present study aimed to evaluate the effect of the salinity on germination and seedling growth in four different vegetable crops viz., tomato, chilli, cucumber and bhendi. In this study, germination percentage (%), shoot length (cm), root length (cm), root to shoot ratio, fresh and dry weight (g) were recorded at four different salinity levels (50 mM, 100 mM, 150 mM and 200 mM NaCl) and one control (0 mM NaCl). Significant differences were observed in all the traits in all crops in this study. Based on the germination percentage, by comparing the four crops, cucumber had the highest tolerance to the salinity which was followed by bhendi. The crops of tomato and chilli were more sensitive to salinity.

Comprehensive Evaluation of Salt Tolerance in Asparagus Germplasm Accessions (Asparagus officinalis L.) at Different Growth Stages

“…It is well known that salt stress severely impacts crop production worldwide by reducing growth and yield [14,15]. Specifically, the growth parameters of different germplasms show significantly different responses to salt stress, such as the germplasms of cucumber, tomato, and chilli [6][7][8]. In asparagus, we also found that 95 germplasm accessions exhibited different salt tolerance with a large variation.…”

“…In recent years, considerable research on the identification of salt-tolerant germplasm has been carried out in multiple vegetables around the world, such as cucumber, tomato, and chilli [6][7][8], from which some success and experience have been achieved. However, in asparagus, the research is still in the initial stage and lacks depth and breadth.…”

“…However, in asparagus, the research is still in the initial stage and lacks depth and breadth. From many previous studies, we know that plant salt tolerance was evaluated at the germination stage and seedling stage due to their prerequisite roles in determining yield [6][7][8] while the results were usually different in the entire growth period, including the adult stage, another critical stage closer to actual production. us, salt-tolerant identification at the adult stage must be conducted before plants are applied in actual production in saline-alkali soil, which will be more reliable combined with identification at the germination stage and seedling stage.…”

Determination of effects 24-epibrassinolide in tomato (Solanum lycopersicum L.) shoot tip cultures under NaCl stress

“…Salinity negatively impresses plant growth by disturbing water balance, specific ion toxicity, creating an imbalance in plant nutrition, and combinations of these factors, and affecting plant physiological and biochemical processes (Loganayaki et al 2020). Ionic effects related to NaCl stress induce damages of macromolecules and compartments of the cells such as cell membrane, cell wall, lipits, proteins, and nucleic acids as a result of nutritional disorders in leaves and meristems (Aly et al 2012).…”
