Biochemical Analysis of Meloidogyne Species Infecting Vegetables in Western Parts of India*

Populations of Meloidogyne were collected from 5 districts of Western U.P and maintained in the green house on tomato and brinjal. For the purposes of species identification, nematodes from each population were examined using perineal pattern analysis However biochemical and Cytological analysis was also carried out to find out the changes occurred after feeding on the host plants. Meloidogyne species were very similar and their precise identification required high qualification and combination of morphological and biochemical methods. Biochemical analysis done by using various methods for organic constituents and Atomic absorption spectroscopy for inorganic constituents. The analysis of various biochemical components showed a visible difference in the biochemical composition of juveniles and females.
