| 摘 要： | 不同树种生长所需的营养物质要靠树体的木质部进行输导,其主要功能是输导水分和无机盐。试验采用改良的Jeffrey离析法,通过对扁桃、银杏,以及富士(CK)苹果枝条次生木质部细胞进行解离,研究了不同树种的导管细胞类型与其树体生长特性之间的关系。试验结果显示,扁桃导管类型为螺纹导管,银杏与富士(CK)苹果均为孔纹导管;与其他供试树种相比,银杏不仅次生细胞加厚明显,且具有较多的畸形细胞;扁桃导管平均长度为21.240μm,银杏导管平均长度为23.375μm,富士苹果导管平均长度为21.536μm。试验获得了扁桃和银杏枝条次生木质部细胞解剖学新资料,为研究这些品种的生物学特性,提供了细胞生理依据。

| Abstract: | The necessary growth nutriment lead by xylem for different varieties of trees,the xylem can transport moisture and inorganic salts. This test adopts improved Jeffrey eduction,study different pipe cell type and its growth relation of characteristic for cell anatomical research on xylem of A. communis L.,Ginkgo L. and Fuji apple. The results showed that the type of the trachea with A. communis L. is whorl trachea,Ginkgo L.and Fuji apple are pitted trachea;Ginkgo L. is not only cells wall thickening but also h... |
