Implications of exposing mungbean (Vigna radiata L.) plant to higher CO concentration on seed quality.

Understanding the crop response to elevated carbon dioxide (e[CO]) condition is important and has attracted considerable interest owing to the variability and crop-specific response. In mungbean, reports are available regarding the effect of e[CO] on its growth, physiology and yield. However, no information are available on the germination and vigour status of seeds produced at e[CO].

Effect of elevated carbon-dioxide on plant growth, physiology, yield and seed quality of chickpea ( L.) in Indo-Gangetic plains.

In the present scenario of climate change with constantly increasing CO concentration, there is a risk of altered crop performance in terms of growth, yield, grain nutritional value and seed quality. Therefore, an experiment was conducted in open top chamber (OTCs) during 2017-18 and 2018-19 to assess the effect of elevated atmospheric carbondioxide (e[CO]) (600 ppm) on chickpea ( JG 14) crop growth, biomass accumulation, physiological function, seed yield and its quality in terms of germination and vigour. The e[CO] treatment increased the plant height, leaf and stem biomass over ambient CO (a[CO]) treatment.
