| 摘 要： | 观察了宜兴苦竹(Pleioblastus yixingensis)开花习性,描述了其花序的形态结构。野外调查观察到宜兴苦竹雄蕊个数3、4、5、6均有,以3为主,补充丰富了苦竹属雄蕊3的数据。硼不是花粉萌发的必需元素。花粉浅染型败育,萌发率仅有5.11%,是宜兴苦竹结实率低的重要原因。河南、江苏、浙江、安徽等地的宜兴苦竹2017年同步开花,结实率不足10%。

| Abstract: | The flowering habit of Pleioblastus yixingensis was observed at first, and the inflorescence morphological structure was described. Genus Pleioblastus has 3 stamens according to the Flora Reipublicae Popularis Sinicae, but the number of stamens with 3, 4, 5 or 6 were observed during field investigation, of which 3 was the majority. These enriched the data of Pleioblastus. The boron was not necessary element during pollen germination. The pollen was stained aborted with germination rate only 5.11%, which was an important reason of low setting of P. yixingensis. Pleioblastus yixingensis in Henan, Jiangsu, Zhejiang, Anhui was synchronized flowering in 2017 with fruiting rate less than 10%. |
