Abstract
Official abstract text for this publication.
Methods of controlling the maturation of plants and/or plant products (e.g. fruit, vegetable, ornamentals, etc.) by manipulating Alternative Oxidize (AOX) activity. An increase in activity hastens the maturation process while a decrease in activity slows or stops maturation.
First claim
Opening claim text (preview).
We claim: 1. A method of storing and subsequently maturing a pear, said method comprising exposing said pear to 1-methylcyclopropene (1-MCP) sufficient to arrest maturation of said pear; and, subsequently, exposing said pear to 0.5 mM or less hydrogen sulfide, wherein the exposure to said hydrogen sulfide results in maturation of said pear evidenced by evolution of ethylene in an amount greater than in the absence of hydrogen sulfide exposure. 2. The method of claim 1 , wherein said hydrogen sulfide is applied as a gas or as a liquid. 3. The method of claim 1 , wherein said hydrogen sulfide is applied by drenching, by spraying or by a slow release method. 4. The method of claim 1 , wherein one or both of said steps of exposing are carried out under pre-harvest conditions. 5. The method of claim 1 , wherein one or both of said steps of exposing are carried out under post-harvest conditions. 6. The method of claim 1 , further comprising a step of cutting or slicing said pears after said first exposing step and before said second exposing step.
