CHANGES OF ANTIOXIDANT DEFENSE RELATED ENZYMES OFVIGNA RADIATA (L.) R. WILCZEK IN RESPONSE TO SALICYCLICACID AND JASMONIC ACID AGAINST M. PHASEOLINAPravallika Sree Rayanoothala, Sunita Mahapatra and Srikanta DasAbstract Charcoal rot is a severe problem on mungbean, and its control is mostly dependent on the use of chemicalpesticides. However, this is not a long-term solution due to environmental concerns and the possibility ofresidues. Induced resistance is one of the most important mechanisms for treating disease under thesecircumstances, since it increases the activity of different defense-related enzymes and non-enzymaticantioxidants. The effects of inducers such as salicyclic acid (SA) and jasmonic acid (JA) at low, medium,and high concentrations, viz. JA (1mM, 2.5 mM, 4 mM) and SA (0.5 mM, 1 mM, 2 mM), on the induction ofresistance to manage In a net house, the illness of mungbean charcoal rot was researched in three different varieties: resistant, moderately sensitive, and vulnerable. When compared to the water sprayed control onun-inoculated plants, elicitor treatments had the highest levels catalase and phenylalanine ammonialyasecontent SA@2 mM was the most effective treatment for raising catalase and phenylalanine ammonialyasecontent content, followed by JA for disease resistance. These modifications can be traced to the workof inducers, and it is a well-known fact that elicitors were utilised to help plants improve their defencemechanisms. |
