【摘要】 为揭示密集型克隆植物在未来气候暖化下的反应格局,在控制实验条件下选用冬小麦接受两种温度和两种养分水平的处理。结果显示:温度对冬小麦的克隆生长、有性繁殖、生物量在各部分间的分配均产生了极显著的影响;而养分对多数性状的影响不显著;并且温度很少与养分发生交互效应。在全球暖化的背景下从克隆植物适应对策的角度对研究的结果进行了讨论。更多还原

【Abstract】 To reveal the response pattern of phalanx clonal plant to future climate warming,the winter wheat was subjected to two levels of temperature and two levels of nutrient availability under control experiment.Our results showed: temperature posed profound significant effects on clonal growth,sexual reproduction,biomass allocation among parts in winter wheat;nutrient availability had non-significant effects on most traits;few interactions between temperature and nutrient availability were observed.The results were discussed under the background of global warming and in the context of adaptive strategies of clonal plants..更多还原
