Abstract

Abstract Initial fruit set was increased on ‘Delicious’ and to a lesser extent on ‘McIntosh’ following a 500 ppm preharvest aminoethoxyvinylglycine (AVG) treatment. Final fruit set was increased by AVG only on ‘Delicious’. One day following a chemical thinner application, ethylene production in check and AVG-treated limbs was similar. AVG did not inhibit naphthaleneacetic acid (NAA) induced ethylene production from either fruits or leaves. June drop from AVG-treated limbs appeared to be increased. Carbaryl reduced fruit set on AVG-treated limbs to the same level as on check limbs, while NAA at 15 ppm on ‘Delicious’ reduced the crop load below that of check limbs. AVG reduced fruit size on ‘Delicious’ (which was not overcome by thinners) but did not reduce fruit size on ‘McIntosh’. The length/diameter (L/D) ratios of ‘McIntosh’ and ‘Delicious’ were increased by AVG, but NAA reduced the L/D ratios on both check and AVG-treated limbs. NAA increased the number of “pygmy” fruit on ‘Delicious’, and when combined with preharvest AVG, the number was twice as great as when NAA was applied alone.
