桂花母树结实观察研究——以湖北咸宁地区为例

Observation on Osmanthus fragrans Seed Tree Fruiting——Taking Xianning, Hubei Province as the Example

成宁地区桂花母树约占2％,一般花期9月,开花较整齐,果实秋、冬、春季生长,种子形态成熟于4月,具有明显的大小年,种子千粒重为352 g.桂花母树种子的产量受遗传品质、体内氮素积累量、光照、机械损伤及开花整齐性等因素影响和制约.

Abstract Osmanthus fragrans seed trees account for 2% in Xianning, flowers open regularly in September, fruits grow in autumn, winter and spring, seeds morphologically mature in April, seeds yield is significantly different between abundant year and deficient year, thousand grain weight is 352 g. The yield of Osmanthus fragrans seeds was influenced and restrained by genetic material, nitrogen accumulation, sunshine and mechanical damage, regularity of flowers.
