中文摘要 | 相思樹造林地之穿落水,幹流水及土壤滲透水完整系統性的收集。收 集液的植物相剋潛能則用萵苣來進行生物分析。植物相剋作用效應的結果如下: 在相思樹開花期所收集的穿落山、幹流水及土壤滲透水對萵苣發芽抑制率各為 30%,60%及75%對幼根生長的抑制率各為23%,33%和48%。氣候因子如雨後 所收集的水樣,亦會影響實驗效應,在全年中旱些時期所收集的穿落水,幹流水 及土壤滲透水有顯著的植物相剋效應,特別是土壤滲透水,可能是因落在土壤中 累積分解的結果。 |
英文摘要 | A systematic collection of throughfall (rain passing through the canopies), stemflow (rain flowing over the stems), and soil percolates was carried out in a Acacia dealbata plantation during one year, and its allelopathic capacity was biotested using Lactuca sativa L. var. Great Lakes. The results showed an allelopathic effect related to flowers: Germination of L. sativa was inhibited 30% by throughfall, 60% by stemflow, and 75% by soil percolates during the blossoming of A. dealbata, while radicle growth of L. sativa was inhibited 23%, 33%, and 48% by the same solutions, Climatic factors, particularly rainfall some days before, were also important. The three types of samples showed significant toxicities during some periods of the year, particularly percolates, which retained toxicity for a longer time, due perhaps to the decomposition of flowers fallen on the ground. |
