摘要: 采用筛分法对天然林中白桂木土壤种子库进行了研究。结果表明:白桂木天然林土壤种子库种子储量少,最大储量为31.9粒/m2,约80%的种子储存于枯枝落叶层中,其土壤种子库的散布格局具有明显的集群分布特征,种子几乎全部分布于冠幅范围内。

Abstract: The soil seed bank of Artocarpus hypargyreus Hance was studied in wildwood by screening. The results showed that the seed bank of Artocarpus hypargyreus Hance was small in reserves and the largest reserve was 31.9/m2. A large number of seeds (about 80%) stored in the litter layer. The seed distribution pattern was obviously in clusters and almost all of seeds distributed in the crown scope.

Key words: Artocarpus hypargyreus Hance, soil seed bank, characteristics
