[Objective]The study aimed to research the effects of water stress on the seedling growth properties and several physiological indexes of Osmanthus fragrans (Thunb.) Lour.. [Method] 5 moisture contents gradients separately (field capacity 10%, 20%, 40%, 60%, 80%) were designed to carry out the experiment in the pot. [Result] The results showed that the height of seedling, the diameter ground of seedling, the chlorophyll content of the leaves and the root vigour of the seedling of Osmanthus fragrans (Thunb.) Lour. in different environment were all in the order of field capacity 60%>field capacity 40%>field capacity 20%>field capacity 80%>field capacity 10%, the free Proline conten of the leaves was in the order of field capacity 10%>field capacity 20%>field capacity 80%>fieldcapacity 40%>field capacity 60%. [Conclusion] The seedling of Osmanthus fragrans (Thunb.) Lour. adapts to the soil moisture environment in a certain extent.
