Influence of salicylic acid on biochemical parameters and antioxidant system in mashbean plants grown under salt stress conditions
Journal Title: Journal of Applied and Natural Science - Year 2016, Vol 8, Issue 4
Abstract
Abiotic stress factors affect almost every aspect of physiology and biochemisrtry of a plant. The present study investigates the role of salicylic acid (SA) in inducing plant tolerance to salinity. The application of 0.5 mM and 1.0 mM SA to mashbean (Vigna mungo L.) plants provided protection against 30mM or 45mM NaCl stress through elevated antioxidant system. The genotypes KUG 363, KUG 310, (salt sensitive), KUG 502 and KUG 529 (salt tolerant) along with UL 338 (as check) were subjected to salt stress. Relative leaf water content (61%) decreased under 45mM salt stress in salt tolerant genotype KUG 529 as compared to control (85%). Leaf water potential was also recorded at 50 DAS in salt tolerant genotype KUG 529 (-2.66 mpa) and in salt sensitive genotype KUG 363(-3.76 mpa) .All the genotypes showed higher accumulation of Reactive Oxygen Species under salt stress. A remarkable decrease was shown in antioxidant enzymes like catalase (179 micro mole/min/g FW) and ascorbate peroxidase (1617 n moles/min/g FW) in KUG 529 . The level of antioxidant system was enhanced catalase (184 micro mole/min/g FW) and ascorbate peroxidase (1853 n moles/min/g FW) in mashbean plants under NaCl stress following SA applications . Thus SA helped in conferring stress tolerance to mashbean plants through enhanced antioxidant system. However, tolerant genotypes responded better than sensitive ones and lower concentration of SA (0.5mM) was more effective.
