摘要

Tokay葡萄種子休眠中對於低溫的需要曾予研究。在0℃，經3天可以使少數種子停止休眠而萌芽；但最適宜的是經過63天。長時間或短時間的浸冷水(20℃)，或短時間的浸熱水(60℃)，都不能取代冷凍的效果。用Benzyladenine(BA)來處理時，將濃度提高到8,000 ppm仍不能促進種子萌芽；然用8,000 ppm的Potassium Gibberellate(GA)却可完全取代冷凍的效果。將種子皮擦傷，GA的最適濃度降到10 ppm。

Abstract The low-temperature requirement for germination of ”Tokay” grape seeds was studied. As little as 3 days of 0°C induced termination of rest in some seeds; optimum germination occured lafter 63 days at 0°C. Neither long-term nor short-term soaking with cold water, nor short-term soaking with warm water, substituted for cold. Benzyladenine up to 8,000 ppm did not obviate the cold requirement. At 8,000 ppm, the potassium salt of gibbe-rellic acid (GA) completely raplaced the cold requirement; at 10 ppm it terminated rest in some of the seeds. When scarified seeds were used, optimum GA concentration for germination was 10 ppm.
