Abstract: Woodwardia japonica and Hicriopteris glauca are often dominant species in the herbarous layer of broad-leaved evergreen forest in the Tiantong National Forest Park, Zhejiang Province. They show a great competing capability and a strong excluding force against other plant species in natural communities. This paper studies on the effect of maceration extracts of W. japonica and H. glauca on the budding and seedling growth dynamics of ten plant species, which include Schima superba, Lithocarpus glabra, Pinus massoniana, Cyclobalanopsis myrsinaefolia, Castanopsis sclerophylla, Castanea sequinii, Sassafras tsumu, Camellia oleifera, Loropetalum chinense and Camellia fraterna. The results show that the maceration extract of W. japonica can restrain remarkably the budding and seedling growth of C. sequinii, S. tsumu and C. oleifera, the restrictive effect on the seedling growth of P. massoniana is weakened gradually, but the maceration extract of W. japonica is promotive slightly to the seedling growth of S. superba. However, the maceration extract of H. glauca can restain the budding and seedling growth of most other species. The maincomponents of maceration extracts of these two ferns have been identified as alkene compounds(such as 3,7-dimethyl-l,6-octadien-3 ol, et al. contained in the extract of W japonica) by IR and GC-MS/DS.
