Abstract: This paper studied the seed germination characteristics of native species Anneslea fragrans in Southern China under the conditions of aril removal, dehydration, PEG osmotic stress, and different light and temperature. Aril removal benefited the seed germination of  A. fragrans. Fresh harvested seeds had higher moisture content (65.6%), and dehydration gave significant impact on their germination. The germination rate decreased with increasing dehydration duration, and the seed viability was completely lost after 48 h continuous dehydration. Soaking in 5%-30% PEG solution for 24 h decreased the seed germination rate significantly, indicating that  A. fragrans seed germination was sensitive to osmotic stress. Light had little effects on the seed germination. The optimal temperature range for the seed germination was 20 ℃-25 ℃, while high temperature inhibited the seed germination. Based on the responses of the seed germination to the test factors, some suggestions were made on the artificial propagation of  A. fragrans.
