Abstract

Armstrong (1982, 1983) predicted that all ramets within a clone should have the same ratio of biomass allocation to sexual reproduction versus vegetative growth. He presented data (1984) that he interpreted as showing that Solidago altissima ramets in a clone do have the predicted constant allocation ratio. Reanalysis of his methods shows that this conclusion was an artifact of his analysis. A simulation using random numbers and Armstrong's analysis showed the same pattern as his data. Data from S. altissima ramets of a single clone grown in a greenhouse experiment, using a different analysis, illustrated that the allocation ratios within a clone can be highly variable.

摘要

阿姆斯特朗（1982年、1983年）预测，克隆体内的所有分株在生物量分配上，有性繁殖与营养生长的比例应该相同。他提供的数据（1984年），他认为表明了克隆体内的一枝黄花分株确实具有预测的恒定分配比例。对他的方法进行重新分析表明，这个结论是他分析的人为结果。使用随机数和阿姆斯特朗的分析方法进行的模拟显示出与他的数据相同的模式。在温室实验中种植的单个克隆的一枝黄花分株的数据，使用不同的分析方法，表明克隆体内的分配比例可能有很大差异。
