摘要

本試驗之目的在打破甘藍自交不親和性障礙，以甘藍商業品種“初秋”為供試材料，計蕾期授粉、花期授粉、氯化鈉（2.5％NaCI、2.5％NaCl＋0.3％H3BO3及5％NaCl＋0.3％H3BO3）、BA（50 ppm、100 ppm及150 ppm）、4.5％CO2等處理項。試驗結果以蕾期授粉者的單莢平均結籽數15.1粒最高，顯著高於其餘四項處理組，次為氯化鈉有4.2～6.1粒種子、CO2有4.1粒種子，最低為BA有0～0.8粒種子、花期授粉有0.3粒種子。在果莢長度比較結果顯示，仍以蕾期授粉者最長，次為BA、氯化納及CO2處理項，最短為花期授粉處理項。

To break self-incompatibility in cabbage is the purpose of this experiment. Treatments included bud pollination, open flowering pollination, NaCI (2.5% NaCI, 2.5% NaCI + 0.3% H3B03及5% NaCI + 0.3% H3B03), BA (50 ppm, 100 ppm, and 150 ppm), 4.5% CO2. With bud pollination, the mean number of seeds per silique (15.11) was significantly higher than that with NaCl, CO2, BA, or open flowering pollination. Variety K-Y Cross was found with 4.18-6.12 self-seeds/silique in NaCI, 4.12 self-seeds/silique in CO2, 4.18-6.12 self-seeds/silique in BA, and 4.12 self-seeds/silique in open flowering pollinations. Silique length was found longest in the treatment with bud pollination, followed by BA, NaCl, and open flowering pollination.
