摘要
研究福建省南靖县和溪南亚热带雨林下木层植物滴水叶尖的发育情况以及滴水大小．该森林滴水叶尖发育程度中等，离叶尖端３ｍｍ处的叶宽平均为２．３７ｍｍ，粗叶木的最小，为０．９５ｍｍ，瓜馥木的最大，为４．９５ｍｍ．水滴大小平均为０．０４４ｇ，日本五月茶的最小，平均为０．０２３ｇ，瓜馥木的最大，平均为０．０７８ｇ．水滴大小与滴水叶尖宽度存在极显著的正相关（ｐ＜０．００１），滴水叶尖越发达，下落的水滴越小．滴水叶尖的作用首先是迅速、有效地排除叶面上的积水，此外可能与对土壤类型的适应有一定的关系．
This paper deals with the driptip development and drip size in a southern subtropical rainforest in Hexi,Fujian Province. Moderate development of driptip had been found in this forest.Leaf width at 3 mm from the tip averaged to 2.37 mm.The most developed driptip was found in Lasianthus chinensis (driptip width=0.95 mm),and the most less developed was in Fissistigma oldhami (driptip width=4.95 mm).Mean of the drip size was 0.044 g. Antidesma japonica had the smallest drip size,and it was 0.023 g,while that of Fissistigma oldhami was the largest(0.078 g).Significant relationship (p<0.001) was observed between drip size and driptip.The more developed the driptip,the smaller the drip size is .Driptip can quick and effectively remove the water from leaves,and furthermore,it might reflect adaptedness to soil type.
