摘要: 为了探讨菵草属的系统学位置,采用次氯酸钠离析法制作叶表皮装片,用光学显微镜对菵草属及其近缘属植物的叶下表皮微形态特征进行观察。结果显示:菵草属及其近缘属,燕麦族和早熟禾族植物的叶下表皮均为典型的狐茅型,具有较高的一致性。脉间长细胞大多为长筒形,细胞壁大多平直,少数波状弯曲;脉间区短细胞稀少或常见;脉上都分布有刺细胞或短细胞;气孔器大多为2~3列;副卫细胞为平行形,少数为低圆屋顶形。叶表皮微形态显示菵草属不应划入虎尾草族,早熟禾族和燕麦族没有明显的界限,支持早熟禾族和燕麦族合并为广义的早熟禾族,菵草属归为广义的早熟禾族。

Abstract: In order to infer the systematic position of Beckmannia, the slides were made by epidermal maceration by sodium hypochlorite method, and the micro-morphology of leaf abaxial epidermis of Beckmannia and related genera was observed with light microscope. The results indicated that the lower epidermis of leaves of Beckmannia and related genera, Aveneae and Poeae plants were typical Festuca type, and had higher consistence. Intercostal long cells were mostly long cylinder with more straight cell walls and few undulating cell walls. The short-cells distributed frequently or rarely in intercostal zonation. The prickles and short-cells distributed in costal zone. The stomatal apparatus had 2-3 rows mostly. The subsidiary cells were parallel, and few subsidiary cells were low dome-shaped. The micro-morphology of leaf abaxial epidermis suggested that Beckmannia should not be placed in Chlorideae. Meanwhile, Aveneae and Poeae had arbitrary boundaries and should be combined into the broader Poeae, and Beckmannia was appropriate to place in the broader Poeae.
