You observed this in your tissue culture project. Your book shows you something similar to what you found in Figure 21.12 on page 636. Cytokinins regulate the cell cycle as we learned early in the semester. Cytokinins delay senescence. You carried out this project at home with isolated wheat primary leaf tips in various solutions of plant hormones.
Cytokinins cause nutrient diversion.
This is shown in a classic experiment in plant physiology diagrammed in Figure 21.15 on Page 640 . Koning, Ross E. 1994. Plant Physiology Website. Go back to the Course Schedule . Go back to Ross Koning's Home Page .
