Impact of elevated CO2
on two successive generations
of CO2 responsive maize (corn)
genotype.
Climate Dynamics 44: 3469-3479.
"Khan et al. (2020) write that "experiments have proved that elevated CO2 brings about various physiological and growth changes in plants."
... Khan et al. report second generation (H-II) plants "showed improved performance under elevated CO2 for [most] morphological and physiological parameters" .
... much higher CO2-induced increases in plant water use efficiency in the second generation (110%) than in the first generation (33%) of CO2 exposure.
... the four Indian researchers conclude "the data of our study clearly indicated that the advantage of elevated CO2 was higher in second-generation maize plants for all the physiological parameters," adding "these physiological changes will certainly increase the sustainability of the crop even in moisture stress conditions."
... thousands of experiments conducted on first generation crops may well vastly underestimate the true impact of this benevolent gas (CO2), which impact appears to increase across generations."
