相反，嫩枝插穗中ABA含量要低于硬枝插穗中ABA的含量，并且随着母树年龄的增加而增加。

On the other hand , the content of ABA in shoot cuttings is lower than that in hardwood cuttings , and increase with raising the age of seed tree .

试验采用随机区组设计，对采穗母树设遮光和喷施叶面肥处理，穗条选取未木质化、半木质化、木质化三种，长度分为3~5cm，5~8cm，15cm以上。

Using block randomization design , we select three kinds of cuttings for non-lignification 、 semi-lignification and lignification , and the length is 3 ~ 5cm 、 5 ~ 8cm and over 15cm respectively by shading and spraying foliar fertilizer with stock maternal tree ;

母树通过更大的菌根网络来覆盖住自己孩子们所在的区域。

Mother trees colonize their kin with bigger mycorrhizal networks .

通过使用同位素示踪剂进行检测，我们发现那些母树

And using our isotope tracers , we have found that mother trees

它便会降落在距离母树较远的地方。

So that they will land some distance away from the parent tree .

保护好它们就是保护好了森林的基因库、保护好了母树和菌根网络。

These are the repositories of genes and mother trees and mycorrhizal networks .

我们把它们称作中心树，或者更亲切地称之为母树。

We call those hub trees , or more fondly , mother trees ,

母树和菌根网络，还有树干和基因，

the mother trees and networks , and the wood , the genes ,

那些就表示幼苗，这些幼苗在这个网络中已经和它们的母树建立了联系。

those are the young seedlings that have established within the network of the old mother trees .

不同母树种子重量分异具有极显著差异（P<0.01）；

But highly significant differences ( P < 0.01 ) in the seed weight among different maternal plant .

因此我们又设计了一个实验，我们把母树和它们的孩子、以及一些陌生的幼苗种在一起。

So we set about an experiment , and we grew mother trees with kin and stranger 's seedlings .

进食地密度随着离母树距离的增加而降低，距母树的距离与传播种子的数量没有相关关系。

Feeding roost density decreased with increasing distance from the parent , but no correlation between distance and seed deposition .

在播种苗床上看，发芽特性和变异个体的出现因母树不同而有变异，但没有发现地域性差异。

In view of nursery bed , the germination property and variation individuals varied with seed bearer but without regional differences .

无性系母树的雌球花主要分布于树冠顶部；雄球花分布遍及整个树冠，但是，不同无性系有差异，可划分为上部型、中部型、下部型和均匀分布型。
