Effect of Salicylic acid on germination, leaf area, Shoot and root growth in crop plants
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2014, Vol 8, Issue 9
Abstract
Seed treatment or foliar application of chemicals like glycinebetaine, kinetin and salicylic acid may increase yield of different crops due to reduction in stress induced inhibition of plant growth. Salicylic acid (SA) is part of a signaling pathway that is induced by a number of biotic and abiotic stresses. It has been recognized as an endogenous regulatory signal in plants mediating plant defense against pathogens. It was shown that exogenous treatment of young maize plants with SA grown under optimal growth conditions provided protection against subsequent low-temperature stress. Besides the obvious visual symptoms this observation was confirmed by changes in chlorophyll fluorescence parameters and electrolyte leakage measurements. SA application inhibited Na accumulation in salinity condition. This main indicate that, seed pretreatment with SA induced a reduction sodium absorption and toxicity, which is further reflected in low membranes injury, high water content and dry matter production.
