| 摘 要： | 沙棘是宝贵的植物资源,在改善生态环境、医学营养学等方面有重要的作用.研究沙棘叶片组织结构和抗旱性可为沙棘的开发利用提供参考依据.通过石蜡切片染色法制作沙棘叶横切的装片,在OLYMPUS显微镜下观察分析了沙棘的叶片厚度、栅栏组织厚度与海绵组织厚度的比值、表皮的角质层厚度、叶片组织结构紧密度和疏松度等叶片组织结构特点,同时探讨了沙棘树种的抗旱性.气孔密度大、栅栏组织/海绵组织厚度比值较大、叶片组织结构紧密、上表皮细胞较小者抗旱性较强.供试的5个品种抗旱性由强至弱依次为:齐棘1号,阿列依,楚伊,阿尔泰新闻,橙色.

| Abstract: | Hippophae is a valuable plant with important functions in improving ecological environment and medical nutrition.Understanding the leaf tissue structure characteristics and the drought-resistant properties of Hippophae can provide a reference foundation for the development and use of Hippophae.The leaf thickness,the ratio of palisade tissue thickness to spongy tissue thickness,the epidermis cuticle thickness and the cell tense ratio(CTR) as well as the spongy ration(SR) of five Hippophae species were observ... |
