Abstract:

In this experiment, 6 cultivars of cut-flower chrysanthemum were employed as experimental materials to study the effects of 5 pollination method on improving the self-compatibility and cross-compatibility in cut flower chrysanthemum. The result indicated: the best was the method of pollinating when the stigmas displayed the late type of “I” and combined with spraying the 3% NaCl and 0.1% borax solution; the second was pollinating when the stigmas displayed the late type of “I”; the method of pollinating when the stigmas displayed the late type of “Y” and combined with spraying the 3% NaCl and 0.1% borax solution had no influence on improving the cross-compatibility; physical method produced the different influence on different cultivars. Pollinating of self-cross when the stigmas displayed the late type of “Y”, we can find that the compatible index of C030 was 0.018, and others was 0. Through pollinating when the stigmas displayed the late type of “I” and combined with spraying the 3% NaCl and 0.1% borax solution, this method overcame the self-incompatibility of C030. According to the observation of fluoroscope, there were many pollens adhesion in the stigmas after pollinating in hybridization. But after self-cross, we can see a few pollens adhesion and germination, but grew abnormally.
