Physiological Responses of Pea Plants to Salinity and Gibberellic Acid

Pea is a seed legume. It rich in cellulose fibre and protein. also significant source of minerals vitamins. In this paper, we set out to better characterize the physiological responses Pisum sativum L. combined effects NaCl, 100 mM gibberellins (GA3). Our analysis revealed that NaCl caused decrease growth resulting reduction root elongation, distribution density, leaf number area, dry matter roots shoots. However, contribution GA3 salty environment induced an increase these different parameters suggesting improving effect hormone on pea presence salt. led disturbance photosynthetic machinery. Indeed, level chlorophyll pigments (a total) activity were decreased compared control plants. exogenous supply restored net CO2 assimilation, but not content. Additional analyses performed salinity/GA3 interaction osmolytes (soluble sugars starch). results showed starch NaCl. The salt-GA3 combination resulted compensation soluble sugar contents contents, beneficial under saline stress conditions. Level three main polyamines putrescine, spermidine, spermine increased significantly all organs salt-treated
