中文摘要 | 本試驗以濕冷層積、溶脫、刻傷及浸漬GA₃等處理‘巨峰’葡萄種子,探討低溫、生長調節劑與物理刻傷等因子對‘巨峰’葡萄種子發芽率的影響。結果顯示‘巨峰’葡萄種子要5℃低溫濕冷層積一段適當的時間方能發芽,以濕冷層積16週之發芽率較高。在進行濕冷層積前流水浸泡3天可有效促進種子的發芽率。刻傷處理則無明顯促進種子發芽的效果。浸泡GA₃處理除種子發芽率隨處理濃度的增加而提高外,並可減少濕冷層積所需的時間及縮短平均發芽天數;在濕冷層積之前或之後浸泡GA₃均可提高發芽率。但高濃度的GA₃處理會導致幼苗,胚莖、第1節間及第2節間生長細長瘦弱,造成幼苗管理的不便。 |
英文摘要 | Improving seed germination of ‘Kyoho’ grape was conducted by a serious treatments including stratification, gibberellic acid, leaching and scarification. Germination of seeds required a proper stratification period at 5℃. The maximum seed germination percentage of ‘Kyoho’ grape was performed by stratification for 16 weeks at 5℃. Before stratification, soaked seeds in runing water for 3 days could enhance germination percentage. Scarification did not cause obvious effect on improving seed germination. Effect of GA₃ treatment on seed germination was more effective on increasing the seed germination percentage and decreasing the average day of germination by higher concentration, but over dosage of GA₃ treatments induced slender growth of hypocotyl and internode resulting in exceedingly tall seedling. |
