摘要: 对小麦族含StH、St、H基因组的披碱草属、偃麦草属、猬草属、拟鹅观草属和大麦属共5属16份材料的胚乳细胞特征进行解剖观察,结果表明不同属种植物种子胚乳细胞存在丰富的多样性,不同物种的胚乳细胞在大小、形状和数量上均表现出差异,但不能很好地反映属以及基因组间的差异。

Abstract: The endosperm cells of 16 Triticeae species with StH, St or H genomes, which belong to Elymus, Elytrigia, Hystrix, Pseudoroegneria or Hordeum, were surveyed in this paper. The results showed that significant variations existed in the size, forms and quantity of endosperm cells in those species. The differences in genera are smaller than those in species, indicating that the characters of endosperm cells have less value in the systematic studies of those genera than in the studies of those species in Triticeae.

Key words: Triticeae, StH genome, endosperm cell, diversity
