Zhao (1) considers our examination (2) of the relationship between deuterium offset (hereafter “Δ”) and stem gravimetric water content (hereafter “W”) across all the study species to be misleading, and instead suggest that data should be analyzed by individual habitat type based on a vague argument that “different habitats/species will behave differently.” Such a suggestion is unjustified as it ignores the fact that the results of our experiment have already ruled out root uptake-related fractionation (which, if present, would justify the use of a habitat type-based approach) as a mechanism underpinning Δ. As a matter of fact, given our demonstration that extraction-associated deuterium depletion …

回复赵:茎水提取过程中所表现出的伪影程度表明明显需要氘校正[生物科学]



赵 ( 1 ) 认为我们对所有研究物种的氘偏移量(以下简称“Δ”)和茎重量含水量(以下简称“ W ”)之间关系的检查( 2 )具有误导性,并建议应对数据进行分析基于“不同的栖息地/物种会有不同的行为”这一模糊论点,按个体栖息地类型划分。这样的建议是不合理的,因为它忽略了这样一个事实,即我们的实验结果已经排除了与根吸收相关的分馏(如果存在,将证明使用基于栖息地类型的方法是合理的)作为支撑 Δ 的机制。事实上,鉴于我们证明了与萃取相关的氘消耗……
