红桤木

红桤木（Alnusrubra）为非豆科共生固氮速生、先锋树种，主要分布在北美太平洋西北部。

As a lowland species , red alder ( Alnus rubra ) is most often observed along the northern Pacific coast .

PEG对红桤木种子的发芽率无影响，但能显著提高幼苗后期的抗水性，PEG浓度越高，幼苗抗性越强。

However , no significant effect of PEG was found on seed germination rate of red alder , but PEG could help red alder to improve the resistance to waterlogging significantly , and a trend was found that the higher the concentration of PEG treatment , the stronger the resistance .

红桤木的苗高生长过程表现出慢-快-慢的节律。

红桤木的遗传多样性主要来自群体内部。

We can conclude that genetic diversity of Alnus rubra mainly from within populations . 4 .

主要结果如下：播种育苗的技术关键包括播种时间与深度、苗床覆盖、苗期水分管理等。试验表明，红桤木幼苗能在南京地区安全过暑和越冬。

The conclusions are as follows : Key technologies of sowing and seedling raising of red aler were recognized including the following aspects : depth and time , coverage of nursery bed , management of moisture , and so on .

通过对2个栽培居群60个样本进行表型特征分析，结果表明红桤木具有丰富的变异，各部位平均变异系数有明显差异，排序为：叶宽叶长叶脉叶长宽比。

Analysis of phenotypic characteristics of 60 samples from two cultivated populations showed that Alnus rubra had abundant variations . The average coefficients of variation were significantly different in different parts . From highest to lowest : leaf width leaf length leaf venation leaf ratio . 2 .
