Woody shrubs in particular , a shrub called fringed sage or Artemisia frigida thrived .

冷蒿VOCs可不同程度的降低种子发芽势、发芽率与发芽指数；抑制幼苗芽与根生长；阻碍侧根（须根）产生；抑制生物量积累与分配。

The germination energy , germination rate and germination index were reduced differently ; buds and roots growth , fibres ( lateral roots ) development , total biomass and biomass allocation were inhibited by VOCs from A. frigida .

冷蒿的养分利用效率较低（以每形成100g碳所需的养分量计算），但在退化草原却是优势物种。

A. frigida has low nutrient use efficiency ( calculated by the amount of nutrients are needed for the formation of 100 g of carbon ), however , A. frigida is the dominant species on overgrazed sites .

冷蒿（Artemisiafrigida）种群伴随着典型草原退化演替的各个阶段，对其所在群落的结构和功能具有重要的影响。

Artemisia frigida populations are present in every stage of degraded succession of Chinese Inner Mongolia steppe . They have important effects on community structure and function , but spatial pattern of Artemisia frigida populations are poorly understood .
