Extended Data Table 1 Percentage change in nutrient content at elevated [CO2] relative to ambient [CO2]

From: Increasing CO2 threatens human nutrition

  1. *‘Number of pairs’ refers to the number of comparisons in which replicates of a particular cultivar grown at a specific site under one set of growing conditions in one year at elevated [CO2] have been pooled and mean nutrient values for these replicates were compared with mean values for identical cultivars under identical growing conditions except grown at ambient [CO2]. In most instances, data from four replicates were pooled for each value, meaning that eight experiments were combined for each comparison (see Table 1 for details of experiments).
