| Abstract: | Water-keeping abilities and transpiration rates of 3 Elytrigia Desv. plants were studied on the culture pan seedlings. Water-keeping ability on turning point, a new concept was suggested. According to this concept, the Water-keeping ability of E.trichophora was much higher than the other two plants. By contrast, transpiration rate of E.trichophora was significantly lower than that of the other two species. |
