拟叶

马尾藻还因其高度分支，浆果状气囊和许多带锯齿边缘的叶片状拟叶而被称为海冬青。

Sargassums are also known as sea Holly because of their highly branched stems with hollow , berrylike floats and many leaflike , sawtooth-edged blades .

形态学指标与遗传多样性指标的相关分析结果显示：分枝节间距、花梗颜色、每簇拟叶数、最长分枝长度、茎粗5个形态学指标与遗传多样性指标之间存在一定的相关性。

The correlation analysis between morphological and RAPD data showed that there were some correlation between internode length , phylloclades number , peduncle color , stem diameter , length of the longest ramification and index of genetic diversity .

统计分析表明：（1）梵净山尖叶拟船叶藓在物种水平有较高的遗传多样性，居群水平的遗传多样性相对较低。

Results suggested that ( 1 ) D.diversiformis from FanjingMount kept a high level genetic diversity , and the genetic diversity is relative low at the population level ;

在黄瓜各生长期内，适度的水分亏缺均有利于茎杆直径的增长，而初瓜期较高土壤含水量有利于叶面积的增长，盛瓜期过低的土壤水分会拟制黄瓜叶面积生长。

Moderate water deficit during every growth stage was conducive to the growth of stem diameter , and the higher soil moisture during early-fruit stage was favored for the growth of leaf area .
