It was showed that c . arborescens ecotype wu was generally the most drought tolerant one except lower than c . arborescens ecotype xj which was the maximum in may , bore comparison with zygophyllum xanthoxylum by estimating seasonally ; c . latens ecotype nx was significantlly lower than c . arborescens ecotype wu , the result was contrary to being known ; c . arborescens ecotype kerqin was significantlly lower than wu ; xj , the maximum in may , showed no else great difference to nx ; c . lanata was high in april and not high afterwards , however its phenological phase presented visible changes as compared with the original life patterns in western america Arborescensecotypexj ) 5月耐旱性表现最强，其他时间与宁夏驼绒藜差别不大；北美驼绒藜( c lanata ) 4月拐点很高， 4月以后耐旱性降低，其物候期与原分布区(美国西部)相比发生了很大变化。驼绒藜属植物在不同季节中蒸腾速率的日变化基本上都为典型的单峰曲线。
