| 中文摘要: |
| 研究国产沉香及其乙醇提取物对植物种子萌发和幼苗生长的化感作用，为拓宽国产沉香来源植物白木香也Aquilariasinensis (Lour.) Gilg页的生态和经济效益提供依据。采用培养皿滤纸法研究国产沉香及其乙醇提取物对黄瓜（Cucumis sativus L.）、白菜（Brassica pekinensi）、萝卜（Raphanus sativus L.）和甜菜心（B. campestris）的种子萌发和幼苗生长的影响。国产沉香块产生自然挥发性物质可促进4种植物种子萌发和幼苗生长袁而沉香乙醇提取液则抑制4种植物的种子萌发和幼苗生长。白木香林中可套种农作物，增加其经济效益。 |
| 英文摘要: |
| The allelopathy of Chinese eaglewood and its ethanol extract was explored on plant seedling growth and seed germination,in order to broaden the ecological and economic benefits of its resource plant Aquilaria sinensis (Lour.) Gilg. The allelopathy of Chinese eaglewood and its ethanol extract on Cucumis sativus L., Brassica pekinensi, Raphanus sativus L. and B. campestris was evaluated by petri dishes filter paper method. Volatiles of Chinese eaglewood stimulated seedling growth and seed germination of the four plants above. On the contrary, its ethanol extract inhibited seedling growth and seed germination. Crops can be planted in the forest of A. sinensis to increase its economic benefits. |
