Biochemical changes in susceptible and resistant black gram cultivars induced by root-knot nematode, Meloidogyne incognita

Biochemical changes in black gram varieties inoculated with root-knot nematode, Meloidogyne incognita were investigated. Observations were recorded in the biochemical modifications relating to various parameters like total chlorophyll, total sugar contents, protein, and proline content during post infection periods. The variation in total chlorophyll, total protein, proline and total sugar content in six cultivars i.e PU 09–36(S), MU-44(S), VBG 11–031 (R), VBG 11–016(R), KUG-715 (R)and NUL-205(R) were studied 45 days after inoculation. Reduced percentage of total chlorophyll contents were observed in inoculated samples than the healthy counterparts. However, an increase in amount of total protein, proline and total sugar contents was observed in the diseased tissues.
