Abstract

Salt stress has adverse impacts on chili pepper (Capsicum annuum L.) growth, development and production. Plant tolerance must be increased to be able to adapt to salinity stress conditions. A factorial experiment with three factors according to Randomized Complete Blocks Design (RCBD) was conducted with three replicates. Polyamine P0, P1, P2 (0, 2, 3 mg L-1 Polyamine), salicylic acid A0, A1, A2 (0, 75, 150 mg L-1), sodium chloride S0, S1, S2 (0, 2000, 4000 ppm) with their interactions were investigated. Salinity had a significant negative effect on the phenotypic characteristics and yield. Polyamine P2, salicylic acid A2 and their interaction (P2A2) were superior, as the highest value was recorded in many of the studied characteristics in comparison to the control. Interaction P2A2S0 gave the highest value compared to other parameters for all processing methods. In summary, this result indicates that the application of polyamine and salicylic acid can effectively reduce the harmful effect of salt stress in chili pepper.
