Abstract
WEAVER1 has shown that autumnal application of gibberellin prolongs dormancy of Vitis vinifera shoots in the following spring. We2 recently reported that application of gibberellic acid in late summer and autumn delayed leaf-fall of several woody species; further observations on these plants this spring have shown that in many of them dormancy was prolonged. Thus this unexpected response to gibberellins may not be uncommon.
