选择性去叶对白三叶无性系植物种群的影响

THE EFFECTS OF SELECTIVE DEFOLIATION ONTHE CLONAL WHITE CLOVER POPULATION

在无性系植物中，通过分株去叶阻止光合同化物的运输，从而影响后来新产生部分的生长。本文研究了白三叶在结构水平被干扰所产生的反应，这个反应是通过母匍匐茎和分枝的去叶决定的。所有的去叶处理与对照组相比，总生物量明显降低影响了无性系的干重。具简单结构的白三叶母株与分枝的干重，与对照组相比，都有明显差异。具复杂结构的白三叶，母株干重，彼此间差异不显著，而分枝干重，彼此之间有显著差异。说明新匍匐茎的产生与生物量紧密相关。

おefoliation of ramets in a clonal species affects the subsequent growth of newly developing parts by preventing translocation of photoassimilates In this paper, the hypothesis is tested that the structural level at which a clone responds to such interference, and the response it displays, will be determined by the branches which are defoliated All defoliation treatments resulted in significant lower total biomass production than in the control clones The pattern of leaf removal affected clone dry weight Dry weight of parent siblings and branches in a simple structural white clover were different with control clone Dry weight of parent siblings in a complex structure were not different with control clone, in contrast, branches were obvious different Show stolon production closely resembled those for biomass
