摘要:
<正>水杉生化他感作用生物测定的结果表明:水杉通过淋洗、根系分泌物和挥发作用等途径释放他感物质,对小麦种子的萌发和小麦、青菜幼根、幼苗的生长产生不同的影响。他感物质浓度高时显著抑制植物的生长发育,随着浓度的降低,这种抑制作用会逐渐减弱、消失甚至转变为促进作用。不同的受体植物对他感物质的反应也有差异。在供试的受体植物中,小麦种子萌发及幼苗、幼根生长受他感物质的影响小于青菜,这一结论可作为复合农林业系统植物配置的参考。
Abstract:
The allelopathy of Metasequoia glyptostroboides was studied. Bioassay of volatiles of M.glyptostroboides and aqueous extracts of soils under the M.glyptostroboides woods, showed that the allelopathy effects on the germination of seed (Triticum aestivum) and the growths of seedlings (T. aestivum and Brassica chinesis). The germinating energy of wheat was decreased by an extract of the soil. The root stem growths of the seedlings were inhibited significantly in high concentrates by an extract of surface layer soil but not by the aqueous of deep layer soil. An aqueous extract stimutated the growth of root and stem in a low concentration. The volatile of M.glyptostroboides leaves also inhibited growth of the root and stem of the seedlings.
