摘要
选用爱多收、三十烷醇、槲皮素、盐水(5%NaCl+0.3%硼砂)4种化学药剂对4个芥蓝自交不亲和系(1142、1137、16和9)开花前两周进行花蕾处理,开花后调查花期自交亲和指数和千粒重。结果表明,除了盐水处理的亲和指数在不同试材中存在差异外,其余所有化学药剂处理的亲和指数都显著高于花期自交亲和指数,其中1 mg/L三十烷醇处理对克服芥蓝自交不亲和性效果最佳,0.1 mg/L三十烷醇处理次之,这两种处理的亲和指数都显著高于盐水处理的亲和指数,剩下的化学药剂处理中除了6 mg/L爱多收处理的亲和指数在不同试材中存在差异外,另外3种处理(0.5 mg/L三十烷醇处理、3 mg/L爱多收处理和2 mg/L爱多收处理)的亲和指数都高于盐水处理的亲和指数,都有一定的克服芥蓝自交不亲和性效果。
In this study, 4 kinds of chemicals, including Atonik, triacontanol, quercetin and 5% NaC1＋0.3% boric acid solution were used to treat 4 Chinese Kale self-incompatibility lines（1142,1137,16,9） two weeks before flowering, the compatible index and thousand seed weight were investigated by artificial self pollinated after flowering. The results showed that only the compatible index of brine treatmet had differences in different Chinese Kale self-incompatibility lines, the compatible index of other chemical treatments were significantly higher than that of the untreated self-incompatibility plants. Especially, 1 mg/L triacontanol treatment was the best method to overcome the self- incompatibility of Chinese kale, followed by 0.1 mg/L triacontanol treatment, the compatible index of the two kinds of treatments were significantly higher than those of brine treatment. In the rest chemical treatments, only 6 mg/L Atonik treatment was variant in the different experimental materials, the compatible index of the other 3 kinds of treatments （0.5 mg/L triacontanol treatment, 3 mg/L Atonik treatment and 2 mg/L Atonik treatment） were higher than those of brine treatment, which indicated that the 3 chemicals were all effective in overcoming self-incompatibility of Chinese Kale.
