Table 5 Summary of species-specific effects of eCO2 on plant growth and pollen chemistry.

From: Elevated atmospheric CO2 has small, species-specific effects on pollen chemistry and plant growth across flowering plant species

  1. To indicate plant functional traits, superscript letters following the plant species common name indicate plants that can fix N (N) and crop species (C). White boxes indicate a variable with no significant response to CO2 treatment. A grayed-out box indicates a response variable that was not measured for that plant species. Plus signs ( +) indicate where eCO2 led to a significant increase in a measured variable while minus signs (−) indicate the opposite. For pollen secondary metabolites, changes to one or more metabolites are denoted with a delta (Δ). Flowering initiation occurred significantly later for nasturtium plants grown under eCO2 and this is noted as “later”. Round was often a significant predictor of response variables; if a response variable was affected by round this is noted with a single asterisk for experiment 1 (*) and two asterisks for experiment 2 (**) following the variable name.
