| 摘 要： | 通过盆栽实验,研究了匍匐茎草本野草莓在异质性光照条件下的克隆整合。结果显示克隆整合显著增强了野草莓胁迫分株段的生长,损—益分析表明未受胁迫分株没有显著损耗,整个克隆片段的生长得到显著提高。在局部遮荫处理,克隆整合对克隆形态可塑性的修饰作用没有观察到。最后,讨论了克隆植物对环境的生态适应意义。 |
| 关 键 词： | 野草莓 环境异质性 克隆整合 |

| Abstract: | A container experiment was conducted to study clonal integration of stoloniferous Fragaria vesca under light heterogeneity. The results showed that clonal integration greatly enhanced the growth of stressed ramets. Cost-benefits analysis showed that the connected un-stressed ramets did not incur any cost,and the growth of the whole clonal fragments was enormously enhanced. However,the modification of local response of ramets characteristics to shading due to physiological integration was not observed in the experiment. Finally,adaptation of clonal plants to environments were discussed. |
| Keywords: | Fragaria vesca environmental heterogeneity clonal integration |
