- 摘要:
- 以3个在生产上表现优良的黄心菜品种为试材，将萌动种子置于4 ℃低温处理6、12、18、24 d，研究了种子春化处理对黄心菜植株抽薹开花的影响，以期为黄心菜种子繁育、单倍体育种等提供参考依据。结果表明：低温春化处理后，3个黄心菜品种的抽薹、现蕾、初花期、盛花期均显著提前，处理时间超过18 d以后，尽管植株抽薹开花更早，但植株及花薹表现更瘦弱；处理时间与各个表型性状均显著相关，处理时间与叶片数、叶片宽、叶柄长、株幅呈极显著负相关，与叶片长、叶柄宽、薹粗呈显著负相关，与株高、薹长呈极显著正相关。综合分析表明，处理6、12 d抽薹开花时间较晚，而处理24 d虽开花较早，但植株及花薹表现瘦弱，不利于花粉或种子培育，处理18 d植株抽薹开花时间显著提前且综合性状较好。
- Abstract:
- Taking three varieties of Brassica pekinensis (Lour.) Rupr.with excellent performance in production as test materials，the effects of seed vernalization treatment on bolting and flowering of Brassica pekinensis (Lour.) Rupr.were studied by using sprouting seeds treated at 4 ℃ for 6 days，12 days，18 days and 24 days respectively，in order to provide reference for seed breeding and haploid sports seed of Brassica pekinensis (Lour.) Rupr.The results showed that after low-temperature vernalization treatment，the bolting，budding，early flowering and blooming stage of the three varieties of Brassica pekinensis (Lour.) Rupr.were significantly advanced.After more than 18 days of treatment，although the plants bolting and flowering earlier，the plants and flower bolting were thinner and weaker.In the correlation analysis，the treatment time was significantly correlated with each phenotypic character.The treatment time was extremely significant negative correlation with the number of leaves，leaf width，petiole length and plant width，significant negative correlation with leaf length，petiole width and bolt diameter，and positively correlated with plant height and bolt length.The comprehensive analysis showed that the bolting and flowering time of treatment 6 days and 12 days was late，while the flowering of treatment 24 days was earlier，but the plants and bolting were thin and weak，which was not conducive to pollen or seed cultivation.The bolting and flowering time of treatment 18 days was significantly earlier and the comprehensive characters were better.
