Abstract
Abstract Naphthaleneacetic acid (NAA) applied as a spray to apple ( Malus domestica Borkh.) trees, entire limbs, or foliage only, reduced fruit retention but, when applied to fruit only, retention was unaffected. Silver nitrate sprays did not alter the effect of NAA on fruit retention. A galactose spray did not affect fruit retention. Excised fruits from NAA-sprayed trees took up less 14 C-sucrose and lost less 14 C-indoleacetic acid than those from unsprayed trees. 14 C-sorbitol translocation from lateral leaves to growing shoot tips was reduced more by naphthaleneacetamide (NAM), NAA, and ethephon than was 14 C-sucrose. 14 C-sucrose and 14 C-sorbitol translocation was affected by NAM but not by NAA or ethephon. Additional shade of 25% during 2 consecutive cloudy days reduced retention of ‘Delicious’ fruitlets, indicating that a small reduction of metabolites available to young fruit may adversely affect their retention.
