种性状

Both phenotypic plasticity and allometry are the important traits for the invasiveness of plants.

干扰等异质性生境下表型可塑性成为物种生存扩散的有利性状，表型可塑性强的物种更有可能成为广布种。

By using of on the large-scale test flat and giving the control of ground subsidence curves, the results of large-scale tests of two different abutments (gravity type and cross brace type), which were treated with Geocell wedged-shaped flexible slab, were analyzed. The adaptability to ground subsidence and active property of Geocell Wedged-shaped Flexible Slab were achieved.

The bump at the approach abutment, which is the intuitionistic showing form, is the difficult problem of worrying the highway construction. By using of on the large-scale test flat and giving the control of ground subsidence curves in this paper, the results of large-scale tests of two different abutments (gravity type and cross brace type), which were treated with Geogrid, Geocell wedged-shaped flexible slab and lime soil replacement, were analyzed. The adaptability to ground subsidence and active property of Geocell Wedged-shaped Flexible Slab were achieved.

本文利用大比尺模型试验平台，结合给出的地基沉降控制曲线，对黄土填料下土工格室楔形柔性搭板、土工格栅加筋与灰土换填处治两种不同桥台类型之路桥过渡段的大比尺模型试验结果进行了对比研究，对两种桥台类型中各种处治方法的作用性状及对地基沉降的适应性进行了分析。

Three types of cuticular thickening at the polar region of the guard cells are observed: slight cuticular thickening; rod-shaped culicular thickening and rarely T-shaped thickening.With data obtained from the former research and personal observation, the cladistic methods were employed for the phylogenetic analysis of data and trees were rooted byout-group comparison using, the related genus Kadsura. as result, a new system of the genusSchisamdra Michaux was reconstructed, and Schisandra Michaux was subdivided into 2 subgenus, 3 section, 2 series 10 species in this dissertation.

整理有关五味子属植物研究的资料，补充搜集近期发表的资料和本人研究所得数据，以种为基本单元，选择近缘的南五味子属作为外类群，采用PAUP4.0b4a软件对本研究得出的性状数据作分支分析，重建五味子属的系统发育，修订和补充五味子属分类系统，在五味子属下设2亚属、3组、2系、10种。

It is also suggested that the evolution of seed dis-persal systems is mainly determined by a few key dispersers and plants, which may control the evolutionof related traits of other species.

动植物之间还可能发生在种、属或科水平以上的多物种的多配协同进化，或者通过关键种的协同进化来带动其他食果动物和植物相关性状的进化。

Three full-sibling binary CMS lines, 11 back-cross binary CMS lines, 10 half-sibling binary CMS lines, 10 isozygoty CMS lines and five restorer lines were chosen to make 50 single hybrids and 120 modified single cross hybrids by the way of NC Ⅱ design. The plots of F1 were arranged in the field in a randomized complete block design with 2 replications and the combining ability of 7 characters were analyzed using random model.

利用3个全同胞型二元不育系、11个回交型二元不育系和10个半同胞型二元不育系及其10个亲本纯合不育系，分别与南恢04、明恢86、辐恢838、先恢207和密阳46等5个恢复系按照NCⅡ交配设计配制了50个单交种和120个改良单交种，按随机区组的随机模型分析方法，对二元不育系主要性状进行了配合力分析。

In the pot test, with the hybrid mid-rice Liangyoupeijiu as material,4 soil water potential (flooding, 0,-30 and 60 kPa) and 5 nitrogen levels (0, 1.5, 2, 2.5 and 3.0 g/pot) were set up to study the effects of water and fertilizer coupling on growth characters and yield of rice.

方法］在盆栽试验中，以杂交中稻两优培九为材料，设4种土壤水势（淹水、0、-30和-60 kPa）和5种氮肥水平（0、1.5、2、2.5和3.0 g/盆），研究水肥耦合对水稻生长性状及产量的影响。

Super hybrid rice Gangyou 527 was used to investigate the effects of three irrigation regimes(submerged irrigation, dry cultivation, the treatment W2 that damp irrigation before booting stage, shallow irrigation at booting stage, wetting-drying alternation irrigation from heading stage to mature stage) and different amounts of N application on photosynthetic rate, activities of nitrate reductase, glutamine synthetase, glutamate synthase, endopeptidase in flag leaves, bleeding intensity in basal internodes and grain yield during grain filling, and studied correlations among the photosynthesis, nitrogen metabolism enzyme activity and root vigor at this stage.
