| Abstract | ||
| This study was accrued to test the capability of plant growth regulators(IAA,GA3 and mixture of them) in inducing seedlings of Vigna unguiculata resistance against the Aspergillus flavus fungi. The seedlings were aspersed twice (after 30 and 40 days of sowing) by IAA in(0, 50, 100, 150) ppm concentrations , GA3 in (0, 30, 60, 90)ppm concentrations and mixture of them.After 50 days from sowing , the seedlings were aspersed by suspension fungal solution, and the parameters of infection were measured after that in 15 days. The results indicated the positive effect for the use of plant growth regulators in decreasing of seedling infection by Aspergillus flavus . (150ppm) concentration of IAA and (90ppm) concentration of GA3 gave the highest significantly decreasing in percentage of infected leaves, Disease severity, fungal colony diameter, and colony area. This study indicated that plant growth regulators were affective in contributing in promotion the Cowpea resistance against Aspergillus flavus fungi. | ||
