Abstract
臺灣中部低海找地區，由於冬季低溫不足，以致栽植之溫帶果樹，常有早春萌芽不整齊之問題。本報告評估氰胺水溶液處理促進葡萄萌芽，達到調節產期之效果。1%水溶液氰胺可以有效打破巨峰葡萄扞插枝之休眠。其效果與二氯乙醇相似。1月在田間噴施2.5%的氟膠於巨峰葡萄枝條，21天後即開始萌芽。金香葡萄在2月中旬以前最適量之藥劑濃度為4%，2月中旬以後為25%。8月下旬，第一收金香葡萄採收後噴施2.45%之氰胺可誘使落葉，隨後產生第二次萌芽，因此可能於同一年內採收兩次葡萄。氰胺處理於此過程中最重要之功用為促進萌芽整齊，提早採收及增加二收葡萄之產量。
In the central lowlands of Taiwan there is no prolonged period of low temperature during the winter. Therefore, flower bud opening of some temperate fruit trees poses a serious problem. Cyanamide was evaluated as dormancy breaking agent on grapes and for the regulation of grape production season in Taiwan. Cyanamide at 1% aqueous solution was effective and comparable to ethylene chiorohydrin application in inducing bud opening of dormant grapevine cuttings. With application of cyanamide (2.5%) during January to field Kyoho grapevine, bud burst started 21 days after application. The optimum rates of cyanamide applied before and after mid-February to Golden Muscat grapevines were 4% and 2.5%, respectively. Cyanamide at 2.45% aqueous solution application during late August induced defoliation of Golden Muscat grapes followed by bud opening. Cyanamide application immediately after the normal harvest season induced the second flush of shoot growth, making possible the harvesting of two crops per year. The most significant effects of cyanamide application under these circumstances were increased fruit yield and advancement of harvest time of the second crop.
