Influence of Gibberellin on Time of Bud Development in Globe Artichoke12

Abstract

Abstract Gibberellic acid (GA 3 ) was applied to globe artichoke plants prior to bud enlargement in the fall, and to similar plants during bud development in the spring. Single applications of 25 or 50 ppm were adequate to induce accelerated flower bud development. The rate of bud development was more pronounced when GA 3 was applied in the fall. Although total yields from treated and non-treated plants were not significantly different, earliness was increased.
