WebJul 10, 2024 · Cytokinin Discovery Discovery of cytokinin was first started from Haberlandt, German plant physiologist in 1913 that the phloem extracts are used to cause cell division in tubers. In 1921, from another experiment he found that cell division is promoted by soluble factor. The idea of specific substances required for cell division to occur in plants actually dates back to the German physiologist J. Wiesner, who, in 1892, proposed that initiation of cell division is evoked by endogenous factors, indeed a proper balance among endogenous factors. Somewhat later, the Austrian plant physiologist, G. Haberlandt, reported in 1913 that an unknown substance diffuses from the phloem tissue which can induce cell division in the parenchymatic tissue of pota… WebNational Center for Biotechnology Information trutechdoors.com
