PHYSIOLOGICAL ASPECTS OF DROUGHT TOLERANCE IN GROUNDNUT (Arachis hypogala L.)

Abstract

The groundnut cultivars viz., VG 77. JL 24 and CO 2 possess greater drought tolerance characters like higher root-shoot ratios, accumulations of cations. K+ in parti- cular. These characters have contributed for the higher pod yields in groundnut under moisture stress conditions. Thus K+ content in the leaf can also be considered as one of the criteria for the drought tolerance in groundnut.
