Description |
The present investigation had been done to study the effect of micronutrients (Zn, Cu and Mn) on biochemical constituents in clusterbean (Cyamopsis tetragonoloba L.) seedlings infected with Rhizoctonia species. The seedlings were grown under eleven different micronutrient treatments, in earthen pots, filled with inoculated soil. The inoculated soil was prepared by the pretreatment of soil with 250mg (wet weight) of Rhizoctonia inoculum. Similar set was maintained in uninoculated soil. Morphological parameters like fresh and dry weight of shoot and root, shoot and root length decreased with infection but increased with micronutrient treatments. Chlorophyll, non-structural carbohydrate and IVDMD content decreased in inoculated seedlings as compared to uninoculated one. Oxidative enzymatic activities (PPO, POX, PAL and TAL), crude protein content, phenolic content and structural carbohydrates (ADF, Cellulose, Lignin and Silica) increased in inoculated seedlings and this increase was further heightened by micronutrient treatments, to counteract the fungal invasion. On the basis of present study, it was concluded that Zn2+ 20ppm |
