悬铃木

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 families Cercidiphyllaceae, Daphniphyllaceae, Hamamelidaceae and Saxifragaceae are closely located, while the relationships among them remain unsolved even if more repres...

尽管增加了金缕梅科的取样密度，它们之间进一步的关系仍未得到分辨，结合它们的形态特征，连香树科和交让木科应置于金缕梅目内。rbcL基因树上反映出传统的&低等&金缕梅类成员领春木科与毛茛类植物聚在一起；悬铃木科与昆栏树科和水青树科关系较近，而与金缕梅科关系较远；杜仲科与低等金缕类的核心科———金缕梅科的关系似乎较除连香树科之外的其它低等金缕类成员近。低等金缕类植物由一些古老、孤立的科组成，且是多系的。

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。

The life history and habits of Corythucha ciliata was observed in Shanghai, and its occurrence was investigated.

The generations overlapping was obvious between July and August. C. ciliata took place in all 11 districts in shanghai, and the four roads with highest damaging rate were West Longhua Road, Zhaojiabang Road, North People Road and West Yanan Road, where the damage rate was 100%.

悬铃木方翅网蝽在上海11个区均有发生，株被害率最高的4条道路分别为徐汇区龙华西路、肇嘉浜路、松江区人民北路及长宁区延安西路，为害率达100%。

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。
