Analysis of Growth and Resistance to Different Population of Fusarium Solani in Soybean Legume Plant

ABSTRACT:

Experiment was conducted to study the effect of different concentrations (10,000, 100,000 and 1000, 000 cfu) of Fusariumsolani on growth and resistance to soybean (Glycine max (L.) Merr) leguminous plant. Sterilized seeds of Glycine max were sown in 350g of acid washed sand. The plants were regularly watered with complete Nutrient Hoagland solution. Leaves samples were weekly collected for analysis of biochemical tests. The growth and morphology of G. max were adversely affected with F. solani which show damping off seedling root rot. The symptom was first appearing in root. Infected seedling of G. max showed a marked decreased in root, shoot length and discoloration and decay in roots. Stem diameter was also decreased in infected plants as compared with the control plants. There were not marked differences occurring in leaf area but the color of leaves turn yellowish green in infected plants. The infected tissues of soybean with different colonies of F. solani showed the highest level of total phenolic content as compared to healthy tissues.
