摘    要:本文报导了禾本科短命植物的旱麦草[Eremopyrum triticrurm(cmerth)Nevshi]具有特殊的解剖结构,茎在抽穗时,仍具有实心的薄壁组织,此特点在禾本科中生植物中罕见.在根、茎、叶中皆有大型薄壁细胞.茎、叶的表皮细胞及根中柱鞘内的薄壁细胞,它们的细胞壁均增厚,起着机械支持作用.叶的栅栏组织发达,由 2~3层栅栏细胞组成,等面叶,属于C_4植物型,根、茎仅有初生结构,其内部结构简单.

关 键 词:短命植物  旱麦草  解剖结构

Abstract:It is Veported in this essay that;a short-lived plant Eremopyrum triticeum (cmerth) Nevski has peculiar anatomical structure with quite large parenchyma cells in the root, stem and leaf . The wall of parenchyma cell is thick. The palisade tissue is well developed it belongs to four-carben plants. Its root and stem bave only primary structure and their in tevnal structure is very simple.
Keywords:Short lived plant   Eremopyrum triticeum triticeam [(merth) Nevski ] anatomical storucture.
