| 摘 要： | 对白刺的根、茎、叶进行了解剖学研究,结果发现:白刺根系发达,为避盐植物;叶小且簇生,可减少蒸腾面积;根、茎中木质部发达,有利于水分的运输;有含胶细胞,可吸收并贮存大量水分。上述所有特征均与它生长的环境中盐分含量高及干旱有关。

| Abstract: | The anatomical studies on the root,stem and leaf of Nitraria sibirica Pall.The results showed that it has developed root system.Nitraria sibirica Pall.is a sort of plant avoiding salt.Its small cluster leaves can decrease transpiration areas;its developed xylem of root and stem can be benefit in transporting water;it contains the gluey cell which can Absorb and store amount of water.The characteristics above all are related to the high density of salt and the drought in its growing environment. |
