摘要
Although alpine areas are generally characterized by low temperatures,high solar radiation,strong winds,cloudiness,frequent precipitation,and low levels of insect abundance and activity,it harbours high biodiversity.Thus,how these plants reproduce successfully in hostile environmental conditions is a topic of evolutionary biology.Plants in these areas frequently exhibit highly specialized structures to cope with various stresses。
Although alpine areas are generally characterized by low temperatures, high solar radiation, strong .winds, cloudiness, frequent precipitation, and lowlevels of insect abundance and activity, it harbours high biodiversity. Thus, how these plants reproduce successfully in hostile environmental conditions is a topic of evolutionary biology. Plants in these areas frequently exhibit highly specialized structures to cope with various stresses, for example, greenhouse and snowball plants. However, tile specific evolutionary adaptive mechanisms of these specialized structures are still unclear.
