Abstract: 对红树植物银叶树(Heritiera littoralis)的果实和种子进行果形因子:果重(Y)、果长(X1)、果宽(X2)、果厚(X3);果实体积;果实浮力;果实、果壳和种子重量;果壳和种子含水量的测定分析,结果表明:银叶树的果实含水量相对稳定;种子与果壳的重量比例(1.8:1)较大;果实的浮力与果实体积存在显著正相关性(P<0.05,r=0.2995),1/3的果实具有较强的漂浮能力;银叶树果实的各项形态结构指标相对稳定;果重与果厚达到极显著相关(P<0.01,r=0.3557),与果宽达到显著相关(P<0.05,r=0.3186),与果长无显著相关关系(P>0.05,r=-0.0016),果重与果形因子的线性回归模型为:Y=0.388X2+0.4X3-14.165.
