8种短命植物营养器官的解剖学观察

Observation on anatomy of vegetative organ;in 8 species of short-lived plant;

对8种1年生短命植物的营养器官进行了解剖学研究,结果表明,8种1年生短命植物根、茎、叶的结构虽然有一些旱生特点,但总体上看,仍然属于典型的中生植物。因此可以确认,中生结构特点与短的生活周期有关,是对荒漠干旱的一种适应方式。

This paper deals with anatomy structure of vegetative organ in 8 species of short-lived plant. The studies result shows that their root, stem, leaf have a few xerophytes structures. In short, it belongs to mesophytes structures. Mesophytes structures are connected with short lived-history. It is adapted to desert environment.
