摘要

以甘藍初秋品種盆栽於人工氣候室三種不同溫度，20/15、25/20、30/25 °C。結果顯示，生育早期栽植於30/25 °C之甘藍發育較快，但於結球初期外葉老化而落葉多，故結球產量最低。栽植於20/15 °C之甘藍則因溫度低、發育慢，產量居中，25/20 °C最適宜甘藍之生長。分析酒精可溶性醣及澱粉含量顯示；生育初期不同溫度下其葉內糖及澱粉含量均相近，但30/25 °C下其外葉醣含量則顯著降低，高溫下外葉老化，故醣含量降低。採收時20/15 °C之糖含量較高，故20/15 °C有利於醣之貯運，而品質較佳。蛋白質之分析顯示，不同時期均有不同之表現，早期30/25 °C下表現較高，而開始結球則以20/15 °C表現最多。

Cabbage (Brassica oleracca L. var. capitata L.) cultivar KY-cross was cultivated in controlled environment phytotrons. The alternat day/night temperature regimes were 20/15, 25/20, and 30/25 °C. At the beginning, the fastest growth was obsered under 30/25 °C untill head formation stage. Outer leaves were senesense and fell. Finally its yield was the lowest. The optimum temperature for the production of cabbage under 25/20 °C. The growth was slow under 20/15 °C, because of low temperature. However, its alcohol soluable sugar content of harvested head was the higest. The optimum temperature for sugar transformation and storage in cabbage was at 20/15 °C. The sugar content of outer leaf under 30/25 °C was degraded significently, because of leaves senesense under high temperature. The protein content and expression were different in different stages and temperatures. At outer leaves expansion phase, the protein content was the higest under 30/25 °C. At the head formation stage, it was the higest under 20/15 °C.
