摘要: ‘晋甘蓝4号’开花后45~55 d采收的种子,发芽率均达到98%以上;随着种子成熟度提高,
其千粒质量、发芽活力及其POD酶活性、TIC值都显著上升,而EC值显著下降;40~60℃的烘干温度对种子千粒质量和发芽率等无显著影响,但50℃和60℃会使发芽活力以及POD酶活性、TIC值等显著下降。

Abstract: When cabbage was harvested 45-55 days post anthesis, the germination percentages of all trealments could be larger than 98%. The thousand seed mass, germinating vigor, POD activity and TTC value increased considerably with the delay of harvest dates, but EC value decreased considerably. When the seed lots of cabbage were chied at 40-60℃, there were no remarkable influences on the thousand seed mass and germination percentage, but there was remarkable decreases in the germinating vigor, POD activity and TTC value when dried at 50℃ and 60℃.

Key words: Cabbage, Seed, Harvest dates, Drying temperatures, Seed quality
