In this article we will discuss about:- 1. History of Cytokinins 2. Bioassay of Cytokinins 3. Functions 4. Uses. History of Cytokinins: They are plant growth hormones which are basic in nature, either amino purine or phenyl urea derivatives, that promote cytokinesis (= cell division) either alone or in conjunction with auxin. Skoog and co-workers found that callus from intermodal [...]
In this article we will discuss about:- 1. History of Auxins 2. Bioassay of Auxins 3. Functions 4. Uses. History of Auxins: Charles Darwin and his son Francis Darwin (1880) found that the sensation of unilateral illumination was picked up by the coleoptile tip of Canary Grass (Phalaris canarensis). A decapitated coleoptile did not receive the sensation. Coleoptile tip covered [...]
