Nature of resistance in rice (Oryza sativa L) to the root-knot nematode (Meloidogyne graminicola Golden and birchheld). II. Mechanisms of resistance

Proceedings / Indian Academy of Sciences

Abstract

The structural and chemical features of roots of 55 rice varieties were correlated with the degree of susceptibility to the root-knot nematode (Meloidogyne graminicola). Less roots, dense root hairs, highly sclerotised exodermis, narrow cortex and stele, few phloem points, low starch, protein and nitrogen, high lignification, high aspartic acid and alanine contents characterised roots of resistant rices.
