羊草

In the fenced plot of site A, the seed percentage of annual and biannual herbs in soil seed bank reserve was very high, and the percentage was even higher in the unfenced plot.

羊草样地围栏内外土壤种子库内的种子均以一、二年生牧草为主，远多于多年生牧草的数量。而围栏外一、二年生牧草在种子库总贮量中所占的比例更高。

Conversely, grazing could increase the shoot numbers on the rhizomes of Agropyron michnoi, but the internode length was unchanged.

羊草在放牧后两萌蘖枝间的距离显著地缩短，萌蘖节上的枝条数却没有显著差异。

The tolerant species include Stipa grandis and Agropyron michnoi, which did not change in distribution under mowing disturbance.

对内蒙古羊草草原主要植物种群能量现存量对刈割频次响应的研究表明，在17年不同频次刈割干扰影响下，植物种群能量现存量随刈割频次的变化表现出不同的变化趋势，据此可以划分出3个不同的刈割响应类群：受抑种、耐刈种和受益种。

The fertility of F_1 and backcross progenies from crosses between the alloplasmic wheatvarieties Chris with 10 different Aegilops cytoplasms and 77(2),a 1B/1R wheat-ryetranslocation line,was investigated.

The frequency of cells with univalent at MI and with lagging chromosomes and chromosomal bridge at A I in PMC of F1 hybrids of 4 alloplasmic 1BL:/1RS and non-1BL/1RS wheat male sterile lines with Aegilops kotschyi,Ae. variabilis,Ae.ventricosa and Ae.bicornis cytoplasms were systematically investigated,and the relationship between FCU at M I,FCLB at A I and F1 selfed seed set was analyzed.

系统调查了4类异质(粘果、易变、偏凸、二角山羊草细胞质)1BL/lRS、非1BL/1RS小麦雄性不育系与其恢复系杂种F减数分裂中期Ⅰ出现单价体细胞频率，以及后期Ⅰ出现落后染色体和染色体桥细胞频率，并对中、后期染色体变异率与杂种F自交结实率进行了相关分析。

We analyzed the relations of plant ecological type groups and community biomass and environment changes in the grassland communities of Leymus chinensis as edificator along Northeast China Transect.

初步分析了中国东北样带以羊草为建群种或共建种的草原群落植物水分生态类型功能群生物量及其与群落初级生产力和环境变化的关系。

The P. flagellaria clonal population distributing in the Songnen grassland was studied,and we observed the season dynamics of petiole length and the total stolon length as well as pattern of spacer length,compared the numbers of maternal ramets,daughter ramets and single ramets as well as the yearly dynamics of total biomass in 3 years (2003,2005,and 2006). Furthermore,we analyzed the correlation between population quantative character and the community's quantative character.

以松嫩草地羊草草甸内分布的蔓委陵菜无性系种群为研究对象，观测了叶柄长度、匍匐茎总长度的季节动态以及间隔子长度分布格局，比较了3个年份（2003、2005、2006年）的种群母株数、分株数、独立株数和总生物量年间动态，分析了种群数量特征与其所分布的群落的数量特征之间的相关关系。

P. flagellaria population plots were set in north the Leymus chinensis meadow of Northeast Normal University grassland ecological experiment station. P. anserina population plots were set in Yaojingzi grassland nature reserve of Jilin.

蔓萎陵菜种群样地设在东北师范大学草地生态实验站北甸子羊草草甸群落内；鹅绒委陵菜种群样地设在吉林省腰井子草原自然保护区内。
