Wang et al. (Research Articles, 11 December 2020, p. 1295) reported a large decline in the CO2 fertilization effect (CFE) on global photosynthesis, on the basis of changing regression coefficients of CO2 (β) for satellite proxies/products of photosynthesis. We show that their methods cannot robustly estimate CFE, leading to incorrect attribution, and largely neglect CO2 effects on the photosynthetic enzyme ribulose-1,5-bisphosphate carboxylase-oxygenase (RuBisCO).

评论“最近全球二氧化碳施肥对植被光合作用影响的下降”

等人。(研究文章,2020 年 12 月 11 日,第 1295 页)报告称,基于卫星代理/光合作用产物的CO 2 (β) 回归系数变化,CO 2施肥效应 (CFE) 对全球光合作用的大幅下降。我们表明他们的方法不能可靠地估计 CFE,导致不正确的归因,并且很大程度上忽略了 CO 2对光合酶核酮糖-1,5-二磷酸羧化酶加氧酶 (RuBisCO) 的影响。
