Phylogenetic analysis indicated that the deduced amino-acid sequences of BH1-BH4 genes were more closely related to B-hordeins from cultivated barley (Hordeum vulgare L.) than to any other prolamins from wild barley and Aegilops tauschii.

系统分析表明：它们推断的氨基酸序列与栽培大麦中的B组醇溶蛋白具有较高的相关性，与野生大麦和山羊草属的醇溶谷蛋白相似性较低。

Flooding,as a kind of disturbance events,occurred with higher and higherfrequency over the world.To investigate the effects of flooding disturbance ongrassland vegetation and the soil,a comparatively thorough study was conducted onAneurolepidium chinense grassland in Songnen plain,Northeast China.The studysite was located in Sanjiadian National Rangeland in the territory of Da'an city,Jilirprovince,which was partly flooded in 1998.On the study site,Several transectssubjected to different flooding durations and intensities were designed for thecomparative study among them on such aspects as vegetation characteristics,seedbanks,vegetative propagation of rhizomatous plants,distribution patterns ofpopulations,interspecific relations,and physio-chemical properties of soil.Theresults were as follows:(1)Of the functional group composition of the vegetation,with the elongation of the flooding duration or the increase of flooding severity,theratio of hygric and hygro-mesic plants increase,while that of mesic and mesoxericplants decrease,of Therophytes changed unimodally,of Geophytes increased,whileof Hemicryptophytes decreased.

为弄清草地植被及其土壤环境对水淹干扰的响应，在松嫩平原羊草草地1998年部分遭受水淹的吉林省大安市三家甸子草场内设置了经历不同水淹干扰持续时间和不同水淹强度的样带，并在这些样带之间从植被特征、种子库特征、根茎植物的营养繁殖性能、种群分布格局、种间关系及土壤的理化性质等多个方面展开对比研究，主要结果如下：(1)在植被的功能群组成中，随干扰强度的增加和水淹干扰持续时间的延长，湿生、湿中生类植物功能群的优势度比例基本上是逐渐增加的，中生、中旱生类植物功能群的优势度比例则逐渐减小，而一年生植物的优势度比例呈单峰型变化，地下芽植物比例增加，地面芽植物比例减小。

In this paper, we studied seasonal variation of endogenous IAA、 GA_3、ZR and ABA content of Leymus chinensis、 Agropyron michno、 Stipa grandis、 Cleistogenes sguarrosa、 Koeleria cristata、 Carex korshinskyi、 Allium bidentatum、 Artemisia frigida, Kochia prostrate and Potentilla acaulis in different restoring succession stages, which were determined by ELISA in the growing season in 2005. At the same time we recorded the phenological development and growing regulation of each kind of plant.

本文于2005年生长季，对处于不同恢复演替阶段的羊草、米氏冰草、大针茅、糙隐子草、草、黄囊苔草、双齿葱、冷蒿、木地肤和星毛委陵菜十种植物，运用酶联免疫吸附法，测定内源生长素、赤霉素(GA_3)、细胞分裂素和脱落酸含量的季节动态，同时记录每种植物的物候期和生长规律情况。

It should be pointed out that many tropical species such as Ostrea pauluciae,Ostrea sinensis Gmelin,Pleria formosa and Tetraclitella chinensis(Nilsson-Cantell)etc,which have been found in Nanji islands and Yushan islands of Zhejiang,do not appear in Zhoushan sea area.

It应当指出的是，许多热带物种如牡蛎pauluciae ，牡蛎中华格梅林， Pleria福莫萨和Tetraclitella羊草等，已发现的南麂列岛和玉山群岛浙江，不会出现在舟山海域area。

The soil nutrient is detected in five shrub trees, namely Periploca sepium, Sophora davidii, Syringa pekinensis, Ostryopsis davidiana, Caragana intermedia and comparative Bothriochloa ischaemum community. We have evaluated comprehensively on soil nutrient index during the process of shrub community form and analyzed the linear correlation of soil nutrient factors.

以白羊草群落为对照，选取杠柳、狼牙刺、丁香、虎榛子和柠条5种乡土树种为研究对象，测定其土壤养分含量，计算灌木群落形成变化过程中的土壤养分指数(Soil Nutrient Index， SNI)，分析了各养分因子间的线性相关关系。

Leymus chinensis Tzvel., which is widely distributed in East Asia, is an important self-incompatible forage species in Poaceae.

羊草是一种重要的禾本科牧草，主要分布于亚洲东部地区。

Leymus chinensis steppe is one of the unique types of rhizomatous steppe that appeares in middle-Asia. In recent years, plant functional groups have been became a new research focus.

羊草草原是亚洲中部草原特有的一类根茎禾草草原，对其在放牧条件下的草地的研究有助于认识典型草原的整体状况，具有普遍意义。

There was not significant change in 0~10 cm belowground biomass except in the Leymus chinensis community and grazing reduced 0~30 cm belowground biomass except in Stipa grandis.

除羊草群落外，0~10 cm地下生物量随放牧强度的变化不显著；除大针茅群落外，放牧显著降低0~30 cm地下生物量。

4Rotational grazing system increased the light saturation point of Stipa grandis and Leymus chienesis,however,the effection towards light compensive point was not significant.

4划区轮牧提高了大针茅和羊草的光饱和点，但对光补偿点影响不大，因此扩大了其进行光合的光强范围。

After aphid＇s feeding, the increase ratio of gramine were negatively related to ratio of aphid number significantly r=-0.884(superscript *.

在蚜虫取食诱导后，山羊草芦竹碱的含量提高率与蚜量比值呈显著的负相关，相关系数分别为-0.884*。
