| In this study, 4 kinds of chemicals, including Atonik, triacontanol, quercetin and 5% NaCl+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 selfincompatibility 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. |
