Abstract

Differences were found between two peanut varieties in their physiological sensitivity to ethidium bromide (=EB), MNNG and sodium azide (=SA) treatments. Significant interactions were found between the varieties, the mutagens and the soaking periods; however, EB and SA were more injurious to both varieties than MNNG. The Congo variety was more resistant to all treatments than the variety Dixie Anak, Congo also germinated in all cases more rapidly than DA. Low pH (3·0) alone did not reduce significantly the germination of each variety. The possible mechanisms of this apparently specific differential sensitivity are discussed.
