| Abstract: | The extreme xerophytes. Salsola passerina, has a series of character of drought resistance about morphology, anatomy and physiology of water. Salsola passerina has dense epidermal hairs on their leaves, their epidermal cells of leaves are plump, stomata are hollow deeply, water storage tissue is developmental. During whole growth season, there are very low potential water (-49.94 bar), very high both of total water and bound water (310.0-300.7 percentage of dry weight), very high ratio of bound water/free w... |
