摘要
2003～2005年对沙棘的4个种类，不同立地条件的沙棘叶片组织结构进行显微观察研究，结果表明：不同种类沙棘叶片组织结构差异很大，并与其生态适应性密切相关；不同品种叶片组织结构紧密度（CTR值）有较大的差异，CTR值越大，其抗旱性越强，一般中国沙棘的CTR值大于俄罗斯沙棘；同一种类在不同立地条件下其CTR值也有明显差异，在干旱立地条件下，其叶片的CTR值增大。
The tissue structure of seabuckthorn leaves from 4 varieties and different soil condition were observed. It was showed that the tissue structure was closely related to the ecological stability;The tissue structure tense ratio（CTR）of different varieties appeared obviously different.
The bigger the CTR was,the higher the drought resistance was. In general, the CTR of Chinese - seabuekthorn was better than Russia seabuekthorn; In the same varieties, the CTR also had obvious deference in different ecological condition,in drought condition,the CTR of leaf was increased.
