MICROMORPHOLOGICAL STUDY ON THE LEAF EPIDERMIS OF Schizostachyum neesFROM VIETNAM
Keywords:
scanning electron microscopy, Hairs - microhairs,, stomata,, Schizostachyum.Abstract
The foliage leaf epidermis of 13 Schizostachyum species from Vietnam was investigated by using scanning electron microscopy. The results indicated that hairs - microhairs commonly seen and consist of three types such as long hairs, geniculate hairs, and spineshairs; the stomata of all species on
the lower epidermis are larger, elliptical in shape and arranged in 2 - 5 rows on each side of a vein, each stoma covers finger - like protuberances (papillae) which come forth from the epidermal cells next to the epidermal cells, incline towards the center of stoma. However, the stomata on the lower epidermis covers finger - like protuberances and hairs - microhairs
between leaf blades of different species. These characters were of taxonomic significance at the specific species level.
