But, due to its gaseous nature and high diffusion rate, ethylene cannot be administered to plants without confining them in closed chambers and it is very difficult to be applied in gaseous form in the field. Ethene is a plant hormone which controls growth, seed germination and fruit development. AVG, a potent inhibitor of ethylene biosynthesis can be used to retard fruit ripening and flower fading. Excess ethylene can inhibit elongation growth, cause leaves to fall (leaf abscission), and even kill the plant. Low atmospheric pressure is used to remove ethylene and O2 from the storage chambers that reduces rate of fruit ripening. Produced by Science & Plants for Schools (SAPS), this investigation looks at the effects of ethene of fruit ripening. The Wacker (or Hoechst-Wacker) process was developed by German chemists as a commercial method of oxidising alkenes to carbonyl compounds. Since, the pH of plant cells is less acidic (about 6); ethephon breaks down in plant cells and releases ethylene which exerts its hormonal effect. Uses. It also promotes fruit set. Ethene is used in the preparation of solvents like ethylene glycol, dioxane, etc. (c) Contrary to the above, reverse measures are often employed on commercial scale to reduce rate of ripening, preventing over ripening to enhance post-harvest preservation of fruits and to increase longevity of cut carnations and other flowers by inhibiting or reducing the natural biosynthesis of ethylene in plant tissues or removing ethylene from storage chambers. Other commercial uses of ethephon (ethylene) are: (i) To induce fruit thinning (fruit drop) in cotton, cherry and walnut.
