摘要

本研究目的旨在探討胡麻不同授粉方式對種子結實及活力之影響。在胡麻植株開花時，分別進行下列五種不同的授粉方式：開放授粉、人工自花授粉、人工異花授粉、網袋限制授粉及紙袋限制授粉等處理，並在授粉後30天收穫蒴果進行統計分析，結果顯示，開放授粉與其他四種授粉方式均有顯著差異。與人工自花授粉比較，人工異花授及開放授粉等兩種方式，可顯著提高千粒重。在種子之發芽率方面，五種授粉方式間無顯著差異，但在種子活力方面，以人工異花授及開放授粉可顯著增加乾重、芽長及根長等性狀。

The purpose of this study was to investigate the effects of different pollination methods on seed set and seedling vigor of sesame. The following five methods of pollination were carried out during sesame flowing time: open pollination, artificial self-pollination, artificial cross-pollination, pollination limited with net bag, and pollination limited with paper bag. The capsules were collected after 30 days of pollination and statistical analysis was performed. There were significant differences between open pollination and other four pollination methods. Compared with artificial self-pollination, the other two pollination methods, artificial cross-pollination and open pollination, significantly increased 1000-grain weight. There was no difference in seed germination rates among five pollination methods. However, in seedling vigor, the dry weight, bud length and root length can significantly increase by using artificial cross-pollination and open pollination methods.
