假俭草和结缕草营养器官结构对抗逆性的影响

Structure of Vegetative Organs of Eremochloa ophiuroides and Zoysia japonica Related with Resistance

利用光学显微镜和电镜技术,采用石蜡切片法,叶片离析法等实验技术对假俭草和结缕草的茎,叶等营养器官的解剖结构特征和表皮微形态特征作了研究;通过角质层厚度,维管束数目,气孔指数,泡状细胞等数据分析它们之间的抗逆性差别;首次从微形态角度初步了解假俭草和结缕草及其不同种群之间抗旱力,耐践踏性差异的原因。

The micromorphological features of leaf epidermis and stem were investigated under lightmicroscope（LM） and scanning electron microscope（SEM）. The structure of stem and leaf blade showed close relation to the grass drought, trample resistance. In terms of the epidermis, bulliform cell, vascular bundle, and the fibrous girdle of stem, the conclusion that Zoysia japonica from Fuyang in Anhui Province was more tolerant to drought, salt and drown stress than the other, Eremochloa ophiuroides from Jinzhai was the best in trample resistance were obtained for the first time.
