We did in situ experiments to study the influence of a water-borne substance, exuded by the reef anthozoan Condylactis gigantea, on filamentous algae. Algal biomass accumulation on experimental glass slides was significantly inhibited by the exudate. Algal spores and diatoms were present in equal numbers on experimental and control slides, but the exudate inhibited germination of spores and was toxic to developing green, red and brown algae. The algal population on the control slides consisted of early colonizers as well as later successional species and reflected the natural population. The described allelochemic mechanism will be important in interference competition between the anemone and algae. Settling of larvae in supposedly space-limited systems such as reefs is facilitated when algaecovered surfaces are open to settlement.
我们进行了原位实验，以研究珊瑚礁海葵巨大奶嘴海葵分泌的一种水溶性物质对丝状藻类的影响。实验载玻片上藻类生物量的积累受到该分泌物的显著抑制。实验载玻片和对照载玻片上的藻类孢子和硅藻数量相等，但该分泌物抑制了孢子的萌发，并且对正在生长的绿藻、红藻和褐藻有毒害作用。对照载玻片上的藻类群体由早期定殖者以及后期演替物种组成，反映了自然群体。所描述的化感作用机制在海葵与藻类之间的干扰竞争中具有重要意义。当藻类覆盖的表面可供定居时，在诸如珊瑚礁等假定空间有限的系统中，幼虫的定居会更容易。
