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%。
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%.
