| 摘 要： | 以100个大白菜品种的高代自交系为试验材料,研究了种芽春化和绿体春化两种春化方式对大白菜现蕾时间、开花时间的影响。结果表明:种芽春化处理的100个大白菜品种的平均现蕾时间、开花时间比绿体春化处理分别提前了15.0d和11.5d。其中春泉大种芽春化不能使其现蕾和开花,而绿体春化则可以使其现蕾,这可能是因为参与两种春化方式调控的分子机制不同。不同冬性的大白菜品种在两种春化处理方式下,其现蕾时间、开花时间的变化趋势一致,说明两种春化方式对大白菜不同品种的影响具有通用性和一致性。

| Abstract: | Taking 100 advanced inbred lines of Chinese cabbage〔Brassica campestris L. ssp. pekinensis （Lour）Olsson〕as experimental material，this paper studied the effects of plumule- and seeding-vernalization on bolting and flowering times．The results showed that both the bolting and flowering times of plumule-vernalized material were advanced 15.0 days and 11.5 days，respectively，than that of seedling-vernalized material．Besides，only seeding-vernalization without plumule-vernalization，the inbred line of‘Chunquanda’could not promote bolting and flowering，while seeding-vernalization could make it bolting．This phenomenon might due to the different controlling molecular mechanism of these 2 vernalization modes．Chinese cabbage varieties
with different winter natures had consistent changing trend of bolting and flowering under these 2 vernalization treatments，indicating that the effects of these 2 vernalization modes on different Chinese cabbage varieties had versatility and consistency． |
