Major industrial reactions of ethylene include in order of scale: 1) polymerization, 2) oxidation, 3) halogenation and hydrohalogenation, 4) alkylation, 5) hydration, 6) oligomerization, and 7) hydroformylation. In the United States and Europe, approximately 90% of ethylene is used to produce ethylene oxide, ethylene dichloride, ethylbenzene and polyethylene.[11] Most of the reactions with ethylene are electrophilic addition.
Flower initiation - Cucumber plants treated with ethylene increase their number of female flowers and fruits . This process is known as gassensexen in germany
Abscisic acid (ABA) is a plant hormone which functions mainly as a growth inhibitor. Abscisic acid promotes the dormancy in seeds and buds [ this is the opposite of breaking the dormancy]. It also promotes closing of stomata. Abscisic acid promotes falling of leaves
Cytokinins increase cell division by stimulating the production of proteins needed for mitosis. Mitosis is non-sexual cell division that occurs in all living things producing additional cells for body growth.
In your body, mitosis is occurring every day, replacing dead and damaged cells and allowing for growth. If you skin your knee, it's mitosis that grows back the cells you lost.
