Dichotomanthes tristaniaecarpa Kurz, is an endemic and rare ornamental and medicinal plant in south-western China's Yunan and Sichuan provinces. In natural conditions, germination is extremely low and progresses slowly. Different treatments were evaluated to develop a protocol
for accelerating the germination of this species. For dormancy-broken seeds, the condition of 10/20\textdegreeC with a 12 h light period was appropriate. Cold stratification for 60 days resulted in significantly increasing final germination percentages from 13 (fresh seeds) to 97%, the median germination
time (MGT) was approximately 17 d and is therefore recommended as the practical germination pre-treatment for propagating D. tristaniaecarpa by seeds. Moreover, among four concentrations applied, 200 mg\textperiodcenteredL1 of GA3 was more effective for accelerating
germination of 40-d dry stratified seeds and its MGT was about 12 d. Based on the results, 60-d cold stratification (4\textdegreeC) was the optimal means for alleviating the primary dormancy.",
