Abstract

Abstract Five cultivars of cucumber ( Cucumis sativus L.) were found to vary in chlorophyll/cm 2 and total chlorophyll/leaf. Gibberellin (GA) treatments did not change the total chlorophyll content per leaf but all lines responded more to GA 4+7 than to GA 3 in terms of increased leaf area and leaf fresh weight. Treatment with GA 4+7 stimulated the rate of leaf expansion, but caused a reduction in chlorophyll/cm 2 .
