Abstract:

以盆栽培养的入侵植物喜旱莲子草(Alternanthera philoxeroides)以及与其近缘的本地同属植物莲子草(A. sessilis)、外来非入侵植物锦绣苋(A. bettzickiana)为实验材料，研究了南方菟丝子(Cuscuta australis)寄生对三种莲子草属植物生长和克隆繁殖的影响，探讨南方菟丝子寄生对防治喜旱莲子草的可行性。结果显示，南方菟丝子的寄生均显著降低了这三种植物的生物量积累(P < 0.001)、分株数(P < 0.001)和总匍匐茎长(P < 0.001)，并且对喜旱莲子草的抑制作用更明显。研究结果表明南方菟丝子寄生可有效防治入侵植物喜旱莲子草。
Using the invasive plant (Alternanthera philoxeroides), its native congener (A. sessilis) and related exotic non-invasive plant (A. bettzickiana) as experimental materials, we investigated the effects of Cuscuta australis parasitism on the growth and clonal propagation of these three Alternanthera species by pot experiment, with the aim to explore the feasibility of controlling A. philoxeroides by parasitism. The results showed that the parasitism of C. australis significantly decreased the total biomass (P < 0.001), ramet number (P < 0.001) and total stolon length (P < 0.001) of the three Alternanthera species, especially for the invasive A. philoxeroides. The results suggested that parasitism of C. australis can effectively control the invasive plant A. philoxeroides.
