梅雨對種植於台灣高山之獼猴桃開花著果的影響

The Effects of Continuous Rainings on the Fruit Set of Kiwifruit (Actinidia deliciosa (A. chev.) C. F. Liang et A. R. Ferguson) in the Highland of Taiwan

摘要


台灣高海拔(2000公尺)地區,外來獼猴桃商業品種(Actinidia deliciosa)可産生大量的花蕾,但無法著果,主要關鍵在於盛花期常與梅雨季節重疊。Abbott品種常在梅雨前2-3天開花,産量稍可,其他如世界最重要品種Hayward及Bruno, Monty幾乎年年與梅雨季節完全重疊,因此産量極低。尤其是Hayward幾乎無法結果。但是若以人工授粉,則産量顯著增加。軟毛獼猴桃(A. chinensis)則因與台灣野生種A. chinensis Planch. Var. setosa Li花期相同,而比A. deliciousa早10天至兩週開花,著果率幾乎達100%。台灣另一野生種A. latifolia則在8月初開花,結果亦無問題。

The anthesis of Actinidia deliciosa growing in Taiwanese highland is always coincide with the continuous rainings in late spring. The fruit set are always in solo due to the absence of pollinator and susceptibility of Sclerotinia rot. Artificial pollination and early-blooming cultivars have been used to verify the critical factor of continuous rainings in late spring.
