摘要
为了提高青花菜自交不亲和系种子产量,研究了授粉时期对不同熟性青花菜自交不亲和系结荚率、平均单荚籽粒数、种子千粒质量和种子产量的影响。研究结果表明,不同授粉时期对青花菜自交不亲和系种子生产有显著差异,早熟青花菜自交不亲和系在末花期授粉的结荚率、单荚籽粒数、种子千粒质量、种子产量最高,而中熟、晚熟青花菜自交不亲和系在盛花期授粉结荚率、单荚籽粒数、种子千粒质量、种子产量最高。
In order to increase the seed yield of self-incompatible lines of broccoli, we studied the effects of different pollination periods on podding rate, grain number of a single pod, thousand seed weight and seed yield of the self- incompatible lines of broccoli in this paper. The results showed that, different pollination periods affected the seed production of the self-incompatible lines of broccoli significantly. The late flowering period was the best pollination period for early-maturing broccoli cultivar, while the full-bloom period was best for mid-maturing and late-maturing cuhivars, by doing so, we could obtain the highest podding rate, grain number of a single pod, thousand seed weight and seed yield of the three different kinds of broccoli cultivars.
