%X Gordonia acuminata is one of the dominant tree species of evergreen broad leaved forest in Mt.Jinyun, and it occurs in many communities. In the present study, the factors affecting free proline content in pollen of Gordonia acuminata in Mt.Jinyun, and the relationships between pollen free proline content and reproductive yield features of G.acuminata were investigated. It was found that pollen free proline content of G.acuminata in Mt.Jinyun could not be affected by plant age, rather influenced by the community in which plants were growing. G.acuminata plants in evergreen broad leaved forest had the highest pollen free proline content the plants in G.acuminata forest had the intermediate, and the lowest pollen free proline content in the plants was found in G.acuminata Pinus massoniana mixed forest. Apart from fruit setting rate, flower bud yields and fruit yields of G.acuminata plants increased with age. The correlation analysis showed that pollen free proline content was not correlated with flower bud yields, but correlated with fruit yields and very significantly correlated with fruit setting rate. This result confirmed the hypothesis that fertilization related reproductive yield features are affected, and fertilization unrelated reproductive yield features are not affected by pollen free proline content. Due to the very significant correlation with pollen free proline content, fruit setting rate of Gordonia acuminata had the same variation patterns as pollen free proline content among the three communities investigated.
