摘要/Abstract

摘要：

克隆植物种群因其寿命的持久性、空间上的可移动性和繁殖方式的多样化等特征与非克隆植物有很大区别, 在自然生态系统中占有重要地位, 甚至成为优势种或者建群种。该文通过归纳有关克隆植物的种间竞争适应策略研究案例, 阐述了克隆植物的竞争能力差异和影响竞争力的因素; 论述了克隆植物在构件形态、克隆构型、繁殖对策等方面对种间竞争的响应, 以及生理整合作用与种间竞争的关系; 分析了导致某些同类研究的结论不一致的原因, 认为实验对象差异、实验设计、生境条件与克隆植物形态及生理上的时空动态变化等都可能影响实验结果; 提出了全球变化背景下的克隆植物种间竞争及其分子生态学机制等可能是今后需要重点关注的问题。

关键词: 克隆构型, 克隆植物, 种间竞争, 构件形态, 生理整合

Abstract:

Clonal plants have many advantages over non-clonal plants, such as longevity, spatial mobility and two modes of reproduction. Therefore, clonal plants are dominant or constructive species in many natural ecosystems. We review the adaptive strategies of clonal plants to interspecific competition and elaborate the differences of competitive ability. It accounts for the responses to interspecific competition from those aspects, including modular morphology, clonal architecture, reproductive strategy and the relationship between physiological integration and interspecific competition. Those factors lead to different results, such as diversities of experimental materials, conditions of habitat, design of experiments and dynamic spatial changes of morphology and physiology of clonal plants. Key issues that need research are proposed, including clonal plants and interspecific competition under global change and its molecular ecological mechanism.

Key words: clonal architecture, clonal plant, interspecific competition, modular morphology, physiological integration
