以长春市引种的庭院树文冠果为材料，对其开花与结实生物学性状进行观测与研究，结果表明：在2011～2014年的气候条件下，自然花期均在5月份，群体花期为18．2 d，盛花期8．3 d，单朵小花花期为8～10 d；3～4月气温是影响花期的主要因素。观测总小花数量为2527枚，其中；两性花为542枚，雄花为1985枚，两性花平均所占比例为21．4％。株间果实与种子产量、出种率有显著差异，但种子重量差异不大，变动于976～1049 g之间。本研究发现，花瓣内侧基部除具紫红色斑点外，有些花朵还具有黄绿色斑点；顶生花序并非完全分化两性花，而侧生花序也可以分化两性花。

Xanthoceras sorbifolia Bunge planted in Changchun was taken as material to measure and analyze the biological character of flowering and seed setting , results indicated that in the climate condition from 2011 to 2014, overall natural flo-rescences were on May , florescence of groups was 18.2 d, full bloom stage was 8.3 d, florescence of individual was 8~10 d;temperate of March and April was the main influence factor .Total numbers of individual was 2 527, which had 542 hermaphrodite flowers and 1985 male flowers, the average percentage of hermaphrodite flower was 21.4%.There were sig-nificant differences between fruits between plants and seed yield or seeding rate , but the difference of seed weight was not significant, changing between 976 and 1 049 g.This study found that in the basel part of petal inside , flowers had yellow green spots except fuchsia spots;terminal inflorescence did not differentiate hermaphrodite flower , whereas lateral inflones-cence would.
