Abstract:

For protecting a normal reference for bloom, guaranteeing high-quality produce to provide a theory of Prunus mume on the production, and lay a foundation for further research pollen germination and cross-fertilize. We have investigated biological traits of flowers and pollen germination among 47 Prunus mume cultivars, including aroma, the rate of incomplete flower and pollen quantity and measured the rate of pollen germination. Subsequently, we have got some results as follows through the correlative statistics analysis: Chinese cultivars’ aroma is more fragrant than Japanese cultivars’; the rate of incomplete flower covers 0%-59.65%; there was an obvious diversity among the pollen quantity of different cultivars, and the coverage was from 0 to 1265; there was an obvious diversity among the rate of pollen germination of different cultivars, the highest rate was 84.76% and the lowest rate was 0; there was an obvious correlativity between pollen quantity and the rate of pollen germination. Incomplete flowers occupy a high proportion and flowering periods were easily endangered by low temperature, which resulted in Prunus mume yield low and unsteady. This experiment showed that different species of Prunus mume presented a marked diversity among the rate of incomplete flower, pollen quantity and germination.
