Abstract
Preharvest drop control with aminoethoxyvinylglycine (AVG) was assessed by applying 250 mg.liter-1 to limbs of McIntosh apple trees either three weeks or seven weeks before normal harvest.
AVG significantly retarded preharvest drop.
NAA was less effective than AVG for controlling preharvest drop.
The time of AVG application did not influence preharvest drop until four weeks after normal harvest when the AVG applied seven weeks before harvest started to drop more rapidly.
AVG retarded red color development and internal ethylene production.
Fruit treated with AVG were firmer at harvest and when kept at 20C for up 30 31 days.
