Abstract
Reviews were made on research achievements on conservation biology of Magnolia sinostellata in the past 30 years (from 1984 when it was first reported to 2021) in terms of distribution characteristics, breeding system, genetic diversity and adversity stress. There were three reasons for it to be endangered. Fertilization barriers after pollen entered the stigma lead to self-pollination and hybrid sterility or hypo fertility. The community structure was single and unstable. The shading caused by community formation weakened the growth potential of M. sinostellata seedlings. Challenges needed to be faced, such as no researches on male and female gametophyte and embryo of M. sinostellata, interspecific relationship between M. sinostellata and other species, not mature asexual reproduction technology system. Recommendations were put forwarded on further long and systematic monitoring on dynamics of M. sinostellata population for better understanding its endangered mechanism.
