Phenolic compounds in tomato susceptible and resistant to Meloidogyne incognita (Kofoid et White) Chitwood

Abstract

Increased levels of phenolic compounds have been correlated with the resistance of plants to various nematode diseases (Giebel, 1970; Pi and Rohde, 1967). The present investigation was made to assess the phenolic constituents in the leaves and roots of two tomato cultivars resistant and susceptible respectively to the root-knot nematode, Meloidogyne incognita (Kofoid et White) Chitwood. Earlier studies by other workers were confined to the roots only, but as the phenolic compounds are biosynthesised in the leaves and are then translocated to the roots, investigation of phenolic compounds of the leaves was also considered important.
