Abstract:【OBJECTIVE】 To provide material and scientific evidence for the sustainable exploitation of Dysosina versipellis. 【METHOD】 Artificial pollination and resowing was carried out for Dysosina versipellis. 【RESULT】 Through artificial pollination, the flower ripening rates in Miaobashirenshan, Songfengduiwoshan and Huaipinshan increased from 8.1 %, 5.0%, and2.5% respectively to 73.4%, 91.6% and 30.0% respectively; With artificial resowing of cultivated Dysosina versipellis, cultivated seedlings,cultivated tissue culture seedling and tissue culture seedling, the survival rates were 96.7 %, 93. 3%, 50.0%and15.0% respectively. After one year,the roots weight increased 80.0%,86.2%,103% and 120%. 【CONCLUSION 】Artificial pollination markedly increases the ripening rate of Dysosina versipellis, and artificial resowing increases the number of species group and the number of species within the species groups.
