Abstract: | Summary Exogenously supplied DNA and RNA hastened root initiation and also increased the formation of roots on hypocotyl cuttings ofImpatients balsamina with intact apex and cotyledons. IAA appreciably increased the nucleic acid-caused enhancement in root formation. In combination with lowe concentrations of nucleic acids, it event stimulated the growth of roots as well as of hypocotyls. Higher concentrations of nucleic acids were, however, toxic.The research has been partly financed by a grant from the United States Department of Agriculture. One of us (SB) is thankful to the Deparmtent of Atomic Engery of the Government of India for financial assistance. |
