Abstract

Maerophomina phaseolina, isolated from various host (alfalfa, bean, corn, cotton, cowpea, melon, safflower, sesame, sorghum, soybean, olive, pine, sunflower, watermelon) were assayed in reaction to potassium chlorate during 1999-2004. The isolates were grown on Minimal Medium with 25gr/lit potassium chlorate. The experiment was done 2 times, and each time included 20 replications. After 10 days in 25°c and dark, the cultures were investigated in comparison to controls. The results showed that isolates were separated into 2 groups. Bean, corn, cotton, cowpea, melon, sorghum, olive, pine, watermelon isolates were chlorate resistant and grew in dense phenotype, producing numerous microsclerotia on medium containing potassium chlorate. Whereas, alfalfa, safflower, sesame, sunflower and soybean isolates were chlorate sensitive. Sensitive isolates in soybean could be divided into two classes on the basis of growth on chlorate containing medium. One class grew sparsely with a feather like microsclerotial pattern. The other was completely restricted. The dominant phenotype differed between soil and root isolates for each host and among different hosts. These observations suggest that isolates of M phaseolina from various hosts differ in their ability to use certain nitrogenous compounds. Such differences might reflect to metabolic abilities that could lead to HOST SPECIALIZATION within this fungus.
