Community forest development requires a constant supply of high-quality seeds. In addition, sound management of Toona sinensis (surian) seed sources requires a deep understanding of factors affecting seed production. This present study investigated the reproduction characteristics of surian, including flower, fruit and seed productions, variations in the productions of fruits and seeds among trees and among branches, and dendrometric factors that influence the productions of fruits and seeds. Flower production characteristics were observed in 99 panicles, fruit production characteristics were observed in 128 panicles, and seed characteristics were evaluated based on 890 fruits. The number of fruits per panicle ranged from 38 to 646. The number of seeds in fruits ranged from 1 to 35. Fruit size was correlated to the number of filled seeds following a quadratic regression equation. The optimal number of filled seeds was 20 per fruit. Stem diameter, crown width, crown base height, and the number of sub-branches positively influenced the production of panicles per tree, while the crown base height (of the tree) negatively affected the fruit set.
社区森林发展需要持续供应高质量种子。此外，香椿种子源的合理管理需要深入了解影响种子生产的因素。本研究调查了香椿的繁殖特性，包括花、果实和种子产量，树木之间和枝条之间果实和种子产量的变化，以及影响果实和种子产量的树木测量因子。在99个圆锥花序中观察了花的生产特性，在128个圆锥花序中观察了果实的生产特性，并基于890个果实评估了种子特性。每个圆锥花序的果实数量在38至646个之间。果实中的种子数量在1至35个之间。果实大小与饱满种子数量呈二次回归方程相关。每个果实的最佳饱满种子数量为20个。树干直径、树冠宽度、树冠基部高度和分枝数量对每棵树的圆锥花序产量有正向影响，而（树的）树冠基部高度对坐果有负面影响。
