Use of photosynthetic pigment stabilizing agents to regulate ripening and quality in fruits and vegetables

Abstract

Methods and compositions to temporarily delay the ripening, maturation, senescence and pathogen infection of produce such as fruits, vegetables and ornamental plants are provided. The methods involve the application of a photosynthetic pigment and/or membrane stabilizing chemical (e.g. glycine betaine) to produce which is identified as in need of such delay. Application may be prior to harvest, at or during harvest or post-harvest.

1 - 12 . (canceled) 
     
     
         13 . A method of delaying or slowing the ripening or maturation of apples, comprising the steps of
 identifying apples for which delaying or slowing ripening or maturation, senescence, or pathogen entry is desirable; and   applying glycine betaine to said apples, wherein said step of applying is carried out at or after harvest.   
     
     
         14 - 15 . (canceled) 
     
     
         16 . The method of  claim 13  wherein said applying step includes applying an anti-ripening agent selected from the group consisting of 1-methylcyclopropene (1-MCP) and aminoethoxyvinylglycine HCl.
