Rhizosphere and rhizoplane mycoflora of Brassica juncea CV. varuna and EH-3

The rhizosphere mycoflora was found more as compared to non-rhizosphere soil during the various stages of plant growth. Qualitative and quantitative differences were observed in rhizosphere and rhizoplane mycoflora of Indian mustard, Brassica juncea cv. Varuna and EH-3. The data indicates the strict interrelationship between the plant growth stages and the fungi associated with rhizosphere than in nonrhizosphere soil. Rhizosphere mycoflora was abundant during flowering stage than that of seedling and maturity stage of the plant. Important fungi isolated from rhizosphere soil were Aspergillus sp., Penicillium sp., Alternaria sp., Curvularia sp., and Drechslera sp. etc. Though, Alternaria alternata was observed in flowering and maturity stage of EH-3 plants while in Varuna it was observed in all the stages of plant growth.
