Abstract
Present experiment is an attempt to assess the effect of salt stress on morphological characters and endogenous hormones on three capsicum varieties. The capsicum varieties CO1(salt sensitive), K2(moderate salt tolerant) and G4(salt tolerant) were subjected to different concentration of NaCl (25mM, 50mM, 100mM, 150mM and 200mM) for 30 days in controlled green house condition. Result clearly shows the significant decrease in leaves size, fruit weight and plant height and chlorophyll content of all varieties. Decrease in zeatin, auxin and gibberellic acid was highly correlated to tissue damage in individual varieties but ABA expressed increases with lower salt concentration while decreases with high salt treatment for each variety. 200mM salt treatment was found most detrimental for CO1 variety leading to death on 35th day of treatment.
