Effect of seed priming on growth and physiological responses of chili pepper (Capsicum frutescens L.) under salinity stress

Abstract Increasing soil salinity in some agricultural areas due to global climate change is an obstacle horticultural crop cultivation. Chili pepper ( Capsicum frutescens L.) important that has high economic values but the extensive cultivation saline land can reduce yields. Plant tolerance must be increased able adapt stress conditions. One method used seed priming, which pre-soaking seeds increase germination under unfavourable This study aimed determine effect of osmopriming using PEG 6000 on growth and physiological responses chili stress. The experimental design this included two factors: concentration (0, 12.5 25%) 0, 2000, 4000 ppm NaCl. observed parameters were 1) (percentage rate germination, synchronization); 2) (plant height; root length; dry weight roots shoot, number fruits, fruit capsaicin level); 3) analysis (chlorophyll proline levels). Seed with 25% plant Chlorophyll level while decreased 6000. By studying stress, role reducing harmful effects determined.
