| 摘 要： | 目的:通过观察怀地黄不同主栽品种叶的形状,非腺毛和气孔器大小、密度等特征,为怀地黄主栽品种的鉴定及优良品种的选育提供依据。方法:用直尺测量叶片的长度和宽度,在扫描电镜下计数不同主栽品种怀地黄叶表面非腺毛和气孔的密度,测量其长度。结果:叶片长度、宽度及长宽比,非腺毛和气孔的长度、密度等,在怀地黄不同主栽品种间具有差异。结论:叶的形状,非腺毛和气孔的密度、长度等叶的形态特征可以作为怀地黄不同品种间鉴别的依据。

| Abstract: | Objective: To provide theoretical evidences for the identification and selective breeding of different major varieties of Rehmannia glutinosa by comparing their leaf characters such as the shapes, non-glandular hairs and the size and density of stomata. Method: The length,width and the ratio of the length to the width of leaves were measured, and the density and length of the non-glandular hair, the density, size and density of the stomata in the epidermis were measured by scanning electron microscope. Result: The results showed that there were obvious differences in length,width and the ratio of the length to the width of leaves, the density and length of the non-glandular hair, the density and size of the stomata in the epidermis. Conclusion: The morphological characters of the leaves mentioned above may serve as the identification standards of major varieties of R. glutinosa. |
