Effect of salinity on biochemical components of the egg plant (Solanum melongena)

Present study explored the effect of salinity stress on seedling mineral composition, chlorogenic acid and polyphenol oxidase content two genotypes (GT25 GT26) egg plant (Solanum melongena L.). Selected were exposed to (25-150 mM NaCl) along with control. Plants grown in field School Biotechnology, Gautam Buddha University during 2018-19. Drastic impacts as preliminary symptom seen seed germination. Genotype GT25 GT26 proficient germinate only up 100 75 NaCl respectively under treatment. Results showed very poor growth necrotic/ dead tissue germinated seedlings leaves after 30 days salt treatment in100 Accumulation Na+ ions is comparatively lower (67%) concentration. On contrary (Cu, Mn, K) content, enzymatic activity like resulted higher compared when subjected (75 mM). These results indicate that respond induced oxidative by defense systems. The accumulation suggest a role protective metabolites. Hence it can be concluded possess strong tolerance against could an important genotype resource for breeding programme plant.
