The age structure of natural clonal population of Zoysia japonlca is studied by generational and morphological methods. The results show that if the relationship between age and tiller? s morphology has been found, the morphological method is better because it can show the seasonal change of age structure.

采用世代、形态2种方法对野生结缕草种群的年龄结构进行了研究，发现如果在获得关于分蘖形态与年龄相关的较为准确资料的基础之上，用形态方法划分结缕草无性系年龄结构更能反映出种群年龄构成的季节性动态。

It could be concluded that compound fertilizer could improve the trampling resistance of Shanghai JD-1 Zoysia and 50 g/m^2 were optimum application rate.

氮、磷、钾复合肥能够有效减轻践踏对结缕草的胁迫程度，提高结缕草草坪的耐践踏性。

Two sets of parsimony analyses were conducted, one using Bauera as the outgroup and the other using Cercidiphyllum-Liquidambar as outgroups.

数据矩阵中包括了马尾树科及其它&高等&金缕梅类各科，并分别利用Cunoniaceae科的Bauera属，&低等&金缕梅类植物连香树属和枫香树属作为外类群进行分支分析。

All of the most parsimonious trees obtained based on the analyses of these combined data sets recognized three major clades in Fagales:(1)Nothofagus,(2) Fagaceae, and (3) core "higher" hamamelids represented by Casuarinaceae, Ticodendraceae, Betulaceae, Myricaceae, Juglandaceae, and Rhoipteleaceae.

主要结论是壳斗目的八个科分为三支，南青冈科是最基部的分支，壳斗科做为核心高等金缕梅类的姐妹群第二个分出，核心高等金缕梅类聚在一起，并进一步分为两个亚支：第一亚支包括桦木科、核果桦科和木麻黄科；另一亚支则由胡桃科、马尾树科和杨梅科组成，杨梅科是胡桃科和马尾树科的姐妹群。

DNA sequence data of the rbcL gene, the matk gene, and the internal transcribed spacers of nuclear ribosomal DNA involving 14 species representing the Cercidiphyllaceae. Eupteleaceae. Platanaceae, Tetracentraceae. and all the subfamilies of the Hamamelidaceae have been investigated in the present study.

本研究测定了包括连香树科、领春木科、悬铃木科、水青树科和金缕梅科内所有亚科代表共计14个种的rbcL基因，matK基因和18S-26S核核糖体内转录间隔区的序列，并结合原有资料对所有低等金缕梅类及其相近类群进行了分支分析。

The"lower"Hamamelidae traditionally consists of seven families, namely Eupteleaceae, Trochodendraceae, Tetracentraceae, Cercidiphyllaceae, Myrothamnaceae. Platanaceae and Hamamelidaceae.

传统的低等金缕梅类包含7个科，即领春木科、昆栏树科、水青树科、连香树科、折扇叶科、悬铃木科和金缕梅科。

Comprises genera Hamamelis; Corylopsis; Fothergilla; Liquidambar; Parrotia; other small genera.

包含金缕梅属；蜡瓣花属；福氏金缕梅属；胶皮糖香树；其它小型属。

In order to improve the soil in Hobq desert, this paper has dealt with such characteristics of palygorskite clays as gelatination, water absorbency and water conservation.

以改良库布齐沙漠为目的，结合坡缕石粘土特有的成胶性、吸附性和保水性能，用巴拉贡矿区的低品位坡缕石粘土进行了粘土成胶性能的研究。

In order to further study the systematics and evolution of the family Hamamelidaceae, the five modern different classification systems of this family published by Harms (1930), Chang Hung-ta (1973,1979), Bogle et al.(1980), Endress (1989) and Li Jianhua (Li, 1997) are compared and discussed by the author based on the principle and method of study plant systematics.

为了进一步研究金缕梅科的系统与进化，作者详细介绍了该科的分类历史及各个分类系统；根据现代植物系统学研究的原理和方法，着重对金缕梅科的5个现代主要分类系统，Harms (1930)，张宏达(1973，1979)， Bogle et al。

The rbcL gene sequences of six species representing five subfamilies of the Hamamelidaceae and the Platanaceae were determined and used in the phylogenetic analysis on the "lower" Hamamelidae sensu Endress (1989) and its allies newly suggested.

测定了悬铃木科和金缕梅科5个亚科的6个代表种的rbcL基因序列，对低等金缕梅类植物及新近提出的相关类群进行了分子系统发育分析，获得4个最简约树。简约树步长为893，其CI值和RI值分别为0.558和0.591。
