[Objective]To study the biological characteristics of vegetative growth of cultivated Saussurea involucrata in a low altitude region.[Methods]The measure agronomic traits of cultivated S. involucrate were researched,including leaf number,plant height,root length,and fresh weight under different treatments. [Results]The seedling emergence rate could be improved if plots were covered with a straw mat immediately after sowing the seeds. The biomass of spring-sown plants was significantly higher than that of autumn-sown plants. The growth of 1-year-old seedlings was slow from germination to the 45 thday,whereby it increased and reached a moderate rate by 70 d. Characteristics of perennial cultivated plants,such as plant height and leaf number,were stable and changed a little within the current year. Growth of seedlings increased under 60% shade cloth until the stage of 5 true leaves. Cultivated S. involucrata also demonstrated drought tolerance. One-year-old plants could be cut twice in the same year,but 2-and 3-year-old plants four times. Regenerative ability could be promoted by cutting,which was also improved resilience to high temperature and pest damage. [Conclusions] Cultivated S. involucrata in a low altitude region had its own biological characteristics of vegetative growth.
