謝明憲、王仕賢、林棟樑、王仁晃.2003.二氧化碳氣體打破甘藍自交不親和性商業化應用之研究。台南區農業改良場研究彙報 42:45~51。

本試驗之目的在於利用CO2打破甘藍自交不親和性,建立甘藍商業化親本採種生產模式。本研究以甘藍商業品種“初秋”為供試材料,在苗齡達45天時以1000Lux光度,5℃低溫處理45天進行春化處理誘導開花。開花期間配合釋放蜜蜂授粉並採隔日處理3%或5%CO2氣體一次,處理時間為下午6:00至翌日上午9:00,各計處理7次。試驗結果以3%及5%濃度CO2氣體處理的單莢平均結籽數(0.73粒及0.79粒)顯著高於開花授粉者0.30粒及0.34粒,但尚乏經濟採種效益。

關鍵詞:甘藍、自交不親和性、種子生產、二氧化碳

Studies on Commercial Technique of Carbon Dioxide Gas to Overcome Self-incompatibility in Cabbage

Hsing, M. H., S. S. Wang, D. L. Lin and R. H. Wang

Summary

This study was attempted to develop a method to overcome self-incompatibility in cabbage for seed production. Cabbage seedlings (K-Y cross) were vernalised in a growth chamber programmed for 1000 lux. of 16-hrs alternate light period at 5℃ for 45 days. The plants then were grounded in the green house. At the flowering stage the plants were pollinated with honey-bee for 2 weeks. In this period, the plants were treated with CO2 gas at 3% or 5% level every other day for 7 times from 6:00 pm to 9:00 am. Results indicated that the plants treated with 3% and 5% in average produced 0.73 and 0.79 seed per silique comparing to that of 0.32 seed per silique in the treatment without CO2 gas. Though it is breakthrough out it still can not be need for commercial production of cabbage seed. Further studies are needed.
