Anyone use this stuff? Seems like it could be useful for plants that won't ripen, among other things.

List of plant responses to ethylene
- Seedling triple response, thickening and shortening of hypocotyl with pronounced apical hook. This is thought to be a seedling's reaction to an obstacle in the soil such a stone, allowing it to push past the obstruction.
- In pollination, when the pollen reaches the stigma, the precursor of the ethylene, ACC, is secreted to the petal, the ACC releases ethylene with ACC oxidase.
- Stimulates leaf and flower senescence
- Stimulates senescence of mature xylem cells in preparation for plant use
- Inhibits shoot growth except in some habitually flooded plants like rice
- Induces leaf abscission
- Induces seed germination
- Induces root hair growth increasing the efficiency of water and mineral absorption
- Induces the growth of adventitious roots during flooding
- Stimulates epinasty leaf petiole grows out, leaf hangs down and curls into itself
- Stimulates fruit ripening
- Induces a climacteric rise in respiration in some fruit which causes a release of additional ethylene. This can be the one bad apple in a barrel spoiling the rest phenomenon.
- Affects neighboring individuals
- Disease/wounding resistance
- Inhibits stem growth outside of seedling stage
- Stimulates stem and cell broadening and lateral branch growth also outside of seedling stage
- Synthesis is stimulated by auxin and maybe cytokinin as well
- Ethylene levels are decreased by light
- The flooding of roots stimulates the production of ACC which travels through the xylem to the stem and leaves where it is converted to the gas
- Interference with auxin transport (with high auxin concentrations)
- Inhibits stomatal closing except in some water plants or habitually flooded ones such as some rice varieties, where the opposite occurs (conserving CO2 and O2)
- Where ethylene induces stomatal closing, it also induces stem elongation
- Induces flowering in pineapples
