ANTIOXIDANT METABOLISM IN WATER STRESSED PEANUT TREATED WITH DINICONAZOLE
AbstractThe response of alpha-tocopherol, glutathione and ascorbate was studied in peanut (Arachis hypogea L., cv.
NC-17)Â subjectedÂ to waterÂ stressÂ andÂ treated withÂ aÂ triazoleÂ fungicide,Â diniconazoleÂ (DINI).Â There wasÂ no
significantÂ differenceÂ inÂ alpha-tocopherolÂ levelsÂ betweenÂ controlÂ and DINIÂ treatedÂ plants. However,Â aÂ 14%
increase was observed in alpha-tocopherol level in DINI treated, water stressed plants compared to water stressed
plants. Total glutathioneÂ in DINIÂ treatedÂ stressed plantsÂ increased by 13Â andÂ 31% overÂ control and water
stressed plants, respectively. Ascorbate levels decreased significantly in all treatments compared to the control.
These results indicate that DINI alleviates the oxidative damage caused by water stress by increasing total
glutathione levels. However, DINI does not seem to affect alpha-tocopherol and ascorbate levels in peanuts
under water stress.
