環狀剝皮對芒果抽梢、開花及營養的影響

Abstract

為探討環狀剝皮對芒果營養和生殖生長的影響，及其所致養分輸送障礙後肥培管理的因應問題，於民國77年7月在臺南玉井地區當採果後植株抽的第一次梢成熟時對本地種芒果的樹幹進行環剝處理，如此植株可於10月開始萌花序開花，而對照組植株的花穗則遲至11月底、12月初才陸續出現。 In July 1988, 'Tsai-lai' mango trees grown at Yu-Ching, Tainan were girdled on the trunks after maturation of the first post-harvest flush. Girdled trees began flowering from October, but panicles of controls did not emerge until late November or early December.
