کاربرد رزوراترول در افزایش پارامترهای رشدی و بیوشیمیایی گوجه‌فرنگی آلوده به بیماری پژمردگی فوزاریومی

Biological control of plant disease using phytohormenes and secondry metabolits is goal of sustainable agriculture. In this research the effect of Resveratrol drug on induce resistance in tow tomato cultivars against fusarium wilting disease in greenhouse condition was investigated. Comercial captain and Termeh cultivar and Fusrium oxysporum fsp. lycopersici isolate were used in randomized block design with four repetition. Tow 100 and 150µM concentration of Resveratrol in 4-6 leaf stage were applied for this test. Tap water was used to irrigation and plant were monitored in greenhouse with controlled temperature and moisture. Some of the yield components such as root volume and fresh and dry weight of stem and height of aerial parts of treated plants and also the change of some defense enzymes activity such as catalase, Proxidase, polyphenoloxidase and total phenol were measured. The results showed a significant different of growth parameters between all treatments specially in aerial parts at 150 µM concentration of resveratrol in compared to control. But the highest rate change of enzyme activity was related to catalase enzyme in treated Termeh cultivar with resveratrol. The results of this research show that resveratrol drug could be used as a resistance inducer to disease stress. Althout in compare to other resistance inducer as salicylic acid and jasmonic acid in plant pathology has less efficiency but it could be used in plantle production in nursery .
