| 摘 要： | 准噶尔无叶豆是我国荒漠的稀有植物,现已被列入国家重点保护的种类。通过对该植物水分生理生态学特性的初步研究得知:其同化枝水势变化幅度较大,日变化进程为双峰型;蒸腾作用不大,日变化表现为单峰型。蒸腾速率同植物表面温度,大气相对湿度及光照等生态因素有密切关系。经观测统计,在一定的温度范围内,均呈线性关系。

| Abstract: | Eremosparton soongoricum is a rare desert plant in our country.It can be known that, after studying on the hydrologic physi oecologicsecifity of this plant, there is a relatively big change about its'pssimilation branch hydropotential, and daily varing proceeding is a type ofawo-hump, it dose not change a great deal about its' transpiration, and thedaily varing proceeding is a type of single-hump. The transpiration haveclose relation with the temperature of plant surface, air relativelyhumidity, solar radiation and so on of ecologic environment factors. |
