Abstract:
The most important legume crop in the world is mungbean (Vigna radiate L. Wilzeck). Vigna is a member of the Papilinoidae subfamily and Leguminoseae family. It is primarily grown in Asia, but cultivation has recently spread to Africa and the Americas. Vigna radiata, on the other hand, is consumed in the form of sprouts and dry seeds due to its high protein content. Mungbean is a valuable crop that is commonly produced in dry and semiarid environments due to its rapid growth and early maturity properties, as well as its capacity to replenish soil fertility. The fundamental feature of mungbean is that it reduces fertiliser use and provides nitrogen fertiliser to agriculture fields in short supply, strengthening soil structure and giving plant protein, but flowering and maturity times are shortened under stress compared to well-watered circumstances. Crop yields are severely reduced due to irregular annual rainfall and a lack of source management.
Charcoal rot being a major concern on mungbean whose control largely depends on the application of chemical pesticides however it is not the long term solution due to environment concern and risk due to fungicide residues. Under these circumstances, Induced resistance is one of the most dominant mechanism in managing the disease by increasing the activity of various defense related enzymes and non-enzymatic antioxidants. Role of inducers viz. Salicyclic acid (SA), Jasmonic acid (JA) at three different concentrations viz. low, medium and high concentrations, viz. JA (1mM, 2.5 mM, 4 mM) & SA (0.5 mM, 1 mM, 2 mM) were evaluated on induction of resistance to manage Charcoal rot of mungbean in three different varieties viz. resistant, moderately susceptible and susceptible against the disease was studied in net house. Elicitor treatments exhibited maximum content of total phenols, Ascorbic acid content and Orthodihydroxy phenols (OD- Phenols) content as compared to water sprayed control on un- inoculated plants. Among all the treatments, SA@2 mM was most effective on increasing the observed parameters as total phenol content Ascorbic acid content and Orthodihydroxy phenols (OD- Phenols) content followed by JA on disease resistance. Lower amount of phenols and low accumulation of OD-phenols were recorded in healthy plants when compared with infected plants. These changes can be attributed to the role played by inducers and it is well known fact that used elicitors played an important role in enhancing the defense mechanism in plants.
