Observation of the Leaf Epidermis Micro-morphological Characteristics of Lespedeza Michx.

摘要：

The epidermis of Jive materials from four species in Lespedeza Michx. were examined and analyzed using scanning electron microscope (SEM) . 3 important indexes, including epidermal hair density, stoma type and stratum corneum, were compared among five materials. The results indicate that: ①Hairs are abundant on both upper and lower epidermis of the two species of L cuneata and L. davurica, but only present on the lower epidermis of other two species of L cyrtobotrya and L davidii. ②The shapes of the five materials leaves epidermis hairs are almost the same, and there are all large ecphymas with tumor appearance on all the leaves epidermis hairs. ③The stomas of all materials besides L. cyrtobotrya sagged into the leaf epidermis cells, and all materials have developed stratum corneums on both sides.
