Step-by-step solution
F.W. Went isolated auxin from the tips of coleoptiles of oat (Avena) seedlings. E. Kurosawa reported the appearance of symptoms of the bakanae disease in uninfected rice seedlings when they were treated with sterile filtrates of the fungus Gibberella fujikuroi. Skoog and Miller identified and crystallised the cytokinesis promoting active substance, kinetin, from herring sperm DNA. Cousins confirmed the release of a volatile substance (ethylene) from ripened oranges that hastened the ripening of stored unripened ban
