The Correlation of Weather Parameters with Russet of ‘Golden Delicious’ Apples under Orchard Conditions1

Abstract

Abstract The severity of russet on ‘Golden Delicious’ apple ( Malus domestica Borkh.) grown at Ithaca, New York was well correlated with weather parameters. The best correlations were found with humidity parameters although net precipitation was also well correlated. The fruits were especially sensitive to weather conditions during a short (5 day) interval which occurred between 16 and 20 days after full bloom.
