In order to make Maca be introduced to China, the basicproblems related to introduction and planting such as morphology classification, regionlayout, tissue culture and allelopathy were carried out. And the results were as follows:(1) The numerical Taxonomy of Maca and fifteen plants of Lepidium in China wasinvestigated by cluster analysis and the results showed that the method of numericaltaxonomy could be applied for Lepidium and its results were basically consistent with thatof morphology taxonomy and molecular marker such as Pi intron, ITS and cpDNA.

In order to disclose the adaptive strategies and capacity of Potaninia mongolica Maxim, acquired during its evolution history, the whole response system, which was composed of individual morphology plasticity response, organs anatomy structure response, physiological function response of anti-arid and anti-hotness, activities of protective enzymes response, endogenous hormone adjustment response, sexual reproduction strategies response of seeding, dispreading, sprouting and renewing, asexual reproduction strategies response of clonal growth patterns, clonal growth architectures, clonal growth architectures plasticity, heterogeneous resources utilization strategies, endogenous hormone distribution in clonal organs, foraging behavior, risk-spreading, and resource sharing, individual density allocation patterns response, niche differentiation response, species connection response, allelopathy response and biodiversity components response of the plant was profoundly explored in this paper.The studies come to at least four important results:(1) Taking the sensitive response and evading strategy to adapt to environment stress, Potaninia mongolica Maxim is a successful species has lived through the long-term evolution. Nevertheless, it is narrow climate and soil niche and characteristic of vegetation reproduction which has made the plant a rare and endangered species.
