Plant Physiology and Biochemistry - Overview
Aug 29, 2022 - Plant physiology and biochemistry research at the NWU is focused on quantifying the impact of elevated carbon dioxide and air pollutants as well as increased water stress on crops. From such studies, it becomes possible to identify alternative crops that can successfully adapt to shifting climate patterns. The introduction of climate-resilient…http://natural-sciences.nwu.ac.za/climate-change-air-quality-and-impacts/weather-and-weather-modification
