摘要

以5℃低溫進行處理葡萄植株，結果顯示1～2月間5℃低溫處理並未縮短巨峰葡萄之萌芽日數，但可提高萌芽率及促進萌芽後新梢之生長，低溫處理降低植體之生理活性，但萌芽前低溫及氰胺催芽處理後植株生理活性提高。低溫處理後植株萌芽前全可溶性糖含量提高，澱粉含量降低，而可溶性蛋白質及游離胺基酸含量經低溫處理後植體內並未提高。

The vines were treated with different durations of chilling at 5℃ in winter. The results showed that the budbreak days of the first crop could not be reduce by 5℃ chilling treatment in the winter, January to February, but the budbreak rate was increased and the shoot growth after budbreak was promoted. Chilling treatment in the winter could decrease the plant physiological activities of the first crop at the end of treatment, but the physiological activities were higher in the plants treated with both chilling and bud-forcing chemical-hydrogen cyanamide ten days after the end of treatment. After chilling treatment in the winter, the content of total soluble sugars was increased before budbreak of the first crop, and the content of starch was decreased, but the contents of total soluble protein and free amino acids were not seen to be increased even under chilling treatment.
