| 摘 要： | 目的]为更好地了解试管苗生长情况,并对其生长进行调控。方法]采用石蜡切片技术,对唐菖蒲试管苗和大田苗叶片结构进行观察。结果]试管苗与大田苗叶片结构存在明显差异。试管苗叶片厚度、中脉厚度以及叶肉组织厚度与上下表皮厚度明显薄于大田生长的叶片,试管苗表皮细胞较小,排列也比较松散,但规则,其细胞间隙较大、叶片维管组织分化无大田生长叶片明显,叶片上气孔多,因此水分极易散失。结论]该研究为更好地调控试管苗的生长提供了参考。

| Abstract: | Objective] The adjustment and control of gladiolus plantlet growth was better done through the understanding of its growth.Method] The leaf structure of gladiolus plantlet and field seedling was observed with paraffin section technology.Result] There was a obvious difference in the leaf structure between plantlet and field seedling.The thickness of leaf,vein,mesophyll tissue and between upper and lower epidermal of plantlet was significantly thinner than those of field leaf.The epidermal cell of plantlet was smaller,which arrangement was relatively loose,but regulate,with the larger gap among cells and non-significant differentiation of vascular tissue compared with that of field leaf,many more stomata in leaf resulting in easily water-losing.Conclusion] The reference for the study on the better adjustment and control plantlet growth was provided. |
