| Abstract: | This paper deals with an investigation on the structure of Alyssum desertorum stapf's root, stem and leaf, and the relationship between the structure and some biological characters. The leaf of Alyssum desertorum stapf belongs to four-carbon plant. The mesophyll has relatively better developed palisade tissue than common mesephyte. It contains two-to-four-layer palisade cells, and the palisade cells contain chloroplast small in size butlarge in number. The leaf and stem of Alyssum desertorum stapf has many characters to suit high photosynthetic efficacy on it's structure. |
