| Abstract: | To test the relationship of pollen limitations and resource limitations with fruit set,the experiments of pollen limitations to fruit set of Cynanchum otophyllum(Asclepiadaceae)were hand-pollinated in a wild population,while resource limitations to fruit set were performed in a cultivated population.The results were as follows:The fruit set of artificial selfing,natural pollination and artificial out-crossing were 1.7%,2.25% and 24% separately,which showed pollens from different sources had significant effe... |
