Abstract:
This study was carried out by the methods of typical plots investigation and laboratory test aiming at analyzing the survival state and fruiting characteristics of three Sinopodophyllum hexandrum populations in different environmental habitats. Meanwhile, it could provide scientific basis for enhancing wild population quantity recovery. The results showed that more population quantity grow in the habitats of large-area gap (Population A) and bushes (Population C) with a majority of the young individuals, while the minor-area gap (Population B) was the opposite. The development tendency of S. hexandrum populations would be the recession in the future. Spatial distribution pattern of populations was clumped at small scales but random at large scales. The indexes of population A and C, as fruit size，the quantity and quality of seeds，germ inability，were all superior to those of population B. Comparing the mainly environment factors of three populations, that favorable environmental factors for vegetative and reproductive growth of S. hexandrum populations were found，especially certain lighting intensity and fertile soil. Therefore, the favorable environmental habitats for S. hexandrum individuals growth could be artificial to promote the recovery and quantities of S. hexandrum populations in the future.
