Analysis of amino acids and amides in ridge gourd infected by meloidogyne incognita

An experiment conducted at Department of Nematology, O.U.A.T, Bhubaneswar during 2008 to 2010 showed that the biochemical differences of 2 varieties Jaipur long and Abhaya were used as the resistant and susceptible check against Meloidogyne incognita. Among various amino acids, 10 amino acids viz. L-cystine, L-arginine, L-serine, L-glutamic acid, L-alanine, L-glycine, L-aspergine, L-tyrosine L-tryptophan and L-leucine were found to be common in both the varieties. Quantitative increase in various amino acids and amides were observed in the infected plant of both the varieties except L-tryptophan, L-phenylalanine, L-tyrosine, L-arginine, L-histidine and L-methionine by paper chromatographic and TLC scanning technique.
