Abstract

Our study showed that increases in seasonal productivity drive earlier autumn senescence of temperate trees. Norby argues that this finding is contradicted by observations from free-air CO enrichment (FACE) experiments, where elevated CO has been found to delay senescence in some cases. We provide a detailed answer showing that the results from FACE studies are in agreement with our conclusions.

摘要

我们的研究表明，季节性生产力的增加会导致温带树木提前在秋季衰老。Norby 认为，这一发现与自由大气 CO2 富集（FACE）实验的观测结果相矛盾，因为在某些情况下，升高的 CO2 被发现会延迟衰老。我们提供了一个详细的答案，表明 FACE 研究的结果与我们的结论一致。
