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內(nèi)分布的蔓委陵菜無性系種群為研究對象欧美老妇性BBBBXXXX性，觀測了葉柄長度、匍匐莖總長度的季節(jié)動(dòng)態(tài)以及間隔子長度分布格局，比較了3個(gè)年份（2003、2005www黄色视频在线免费、2006年）的種群母株數(shù)、分株數(shù)又黄又爽又色无遮挡18禁网站、獨(dú)立株數(shù)和總生物量年間動(dòng)態(tài)日本岛国视频精品极品视频观看，分析了種群數(shù)量特征與其所分布的群落的數(shù)量特征之間的相關(guān)關(guān)系。

With extension of the stolon , changes of the internode length , branching intensity and ramet length were fit to exponential model .

Lianas or sarmentose shrubs, stolon bearing when pruned, to 4.5 m tall, glabrous except for corolla, latex clear or yellowish.

藤本植物或者具長匐莖灌木，匍匐莖忍受什么時(shí)候給4.5米高欧美黄色网站免费在线看，無毛除了花冠日韩乱码毛片，清楚和淡黃的橡膠刪節(jié)。

The activity of neutral invertase in leaves was higher than other parts, and stolon was ascended, whereas new corm was ascended firstly then descended. The activities of Q-enzyme increased except leaves. The activities of amylase ascended first then descended. The activities of Q-enzyme and amylase in the new corms and cormels were higher than in the leaves and stolons.
