摘要
自然干扰和人类活动经常会使水生植物支离破碎。入侵克隆植物的植被碎片具有很强的定殖和再生长能力,从而导致这些植物迅速蔓延。我们进行了一项案例研究,探讨水位和光照对克隆入侵植物 Alternanthera philoxeroides 定殖和再生的影响。研究中,在三种水位(0、2 和 10 厘米)和两种光照条件(10% 和 80% 的自然光照)下,跟踪了 10 厘米长的 A. philoxeroides 片段的生长情况。结果表明,除了 10%的自然光照和 10 厘米的水位外,其他处理下 A. philoxeroides 的总生物量均高于初始生物量,这表明 A. philoxeroides 片段在大多数条件下都能重新生长。然而,高水位和弱光处理会降低克隆片段的总生物量、节数和贮根生物量,从而抑制其再生、克隆扩展和无性繁殖。创造高水位和低光照的栖息地,例如种植本地挺水植物,可以阻止这种克隆入侵者的扩散。我们的研究为通过创造抑制入侵植物繁殖体定植的生境来控制克隆入侵植物的扩散提供了一个新的视角。
High water levels and low light co-inhibit colonization of fragments from the clonal invader Alternanthera philoxeroides
Natural disturbances and human activities frequently fragment aquatic plants. Vegetative fragments of invasive clonal plants have a high capacity for colonization and regrowth, which results in rapid spreading of these plants. A case study was conducted to explore the effects of the water level and light on the colonization and regrowth of a clonal invasive plant – Alternanthera philoxeroides. In the study, the growth of 10-cm-long fragments of A. philoxeroides was followed in three water levels (0, 2, and 10 cm) and two light conditions (10% and 80% of natural light). Results showed that total biomass of A. philoxeroides under all treatments except 10% of natural light and 10 cm of water level was higher than the initial biomass, which suggested that fragments of A. philoxeroides can regrow under most conditions. However, treatments of high water levels and low light inhibited regrowth, clonal expansion, and vegetative propagation of clonal fragments by reducing their total biomass, number of nodes and storage root biomass. Creating habitats of high water levels and low light, for example, by planting native emergent aquatic plants, can hamper the spread of this clonal invader. Our study contributes a new perspective to controlling the spread of invasive clonal plants by creating habitats that inhibit the colonization of invasive plant propagules.
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
