Abstract: This article describes the anatomical features of the embryos of 13 species of bamboo fruits, discusses the significance of these features in systematical classification as well as the status of each species in the classification system. As experiments proved, the embryonic types of the bamboo fruits are varied and complicated, which evinces the limitation of the previous definition of theembeyo types of the Bambusoideae as F+PP type.

Key words: Bamboo fruit

摘要: 报道了13种竹果的胚体解剖特征,讨论了这些特征在系统分类上的意义。实验证明,竹果胚体的解剖式样是复杂多样的,从而认为,过去把竹亚科的胚型限定为竹型胚,即F+PP型有很大的片面性。竹子的胚型除了与系统分类有一定关系外,还可能与竹子果实类型有关,又可能受其生活环境条件的制约。此外,根据实验,我们发现国内外学者尚未研究的竹胚的某些其它特征,且这些特征与竹子的系统分类也有一定关系,例如,胚体的弯曲程度,胚芽与盾片和胚根与盾片所成角度,中胚轴延伸情况、盾片大小和形状(纵切面观)等,这些特征对于同一种竹子是比较稳定的,而对于不同竹种和不同竹子类群来说总是存在着或多或少的差异。
