Step-by-step solution
The discovery of plant growth regulators involved several key scientists and plant materials: Charles Darwin and Francis Darwin observed phototropism in the coleoptiles of canary grass. F.W. Went isolated auxin from the tips of coleoptiles of oat seedlings. E. Kurosawa discovered gibberellins while studying the 'bakanae' disease in rice seedlings. F. Skoog and his co-workers observed callus proliferation from the internodal segments of tobacco stems, leading to the discovery of cytokinins. Therefore, the correct ma
