| 摘 要： | 于2008年9月初互花米草成熟期，利用WESLER公司生产的PSYPRO水势测量系统测定广西舍浦山口红树林泥沙质土壤生长的互花米草水势日变化，同步测定光量子通量密度、温度、湿度情况，并分析互花米草叶水势的变化规律及其与气象因子之间的关系。结果表明，互花米草叶水势均受光量子通量密度、气温及相对湿度的影响，其中温度对互花米草叶水势的影响最大，而光量子通量密度和湿度对叶水势的影响则相对较小，互花米草水势日变化与3个气象因子间相关性极显著。

| Abstract: | The leaf water potential (LWP) of Spartina alterniflora which is grown in the sediment soil of Shankou mangrove area of Guangxi was measured by PSYPRO water potential guage in Sep.2008,at the same time,variations of LWP and related meteorological factors were analyzed.The results showed that air temperature was the main impact-factor,the order was air temperature>air relative humidity>photo flux densit (PED).The LWP had a negative correlation to the air temperature and the air relative humidity,and a positi... |
