| 摘 要： | 盐度是影响红树植物海漆分布的一个重要限制因子.研究了不同盐度下海漆种子的萌根率、发芽指数、萌苗率等萌发指标以及幼苗的茎高、基径、叶片数、最大叶面积等生长指标.在低盐(5)处理下,种子萌根率,萌苗率,发芽指数与淡水处理差别不明显;中盐(15)条件处理下,种子的萌发显著差于低盐条件下的;高盐(25,35)胁迫下,种子萌发很差,萌根之后不能定植,出现灼根现象.相同盐度处理下幼苗的生长也显示出与萌发相似的状况,高盐(25,35)处理下的幼苗在前两个月相继死去,不能长期存活.

| Abstract: | Salinity is one of the most important factors influencing the distribution of mangrove plant Excoecaria agallocha.Under different salinities,rooting rate,germination index,seedling establishment rate of E.agallocha seed were investigated and also the situation of stem height,base diameter,leaf number,maximum leaf area of E.agallocha seedlings.Results showed that under the low salinity 5,seed germination was similar to that under salinity 0,significantly higher than those under the middle salinity,15.Under h... |
