Abstract: | In light, malformin completely abolished the ability of Ag+to inhibit Ethrel-induced leaf abscission from cuttings of Vignaradiata, even though Ag+ was applied 24 hr before malformin.Malformin itself did not induce abscission in the light. However,Ag+ was active on cuttings which had been pre-treated with malforminfor 2 days in the light. No evidence was obtained to suggestreaction between malformin and Ag+. In the dark, Ag+ had noeffect on stimulation of leaf abscission by malformin. (Received March 7, 1981; Accepted May 12, 1981) |
