Abstract

‘Redblush’ grapefruit borne on young fruiting trees and grafted on sour orange seedlings were exposed to natural and artificial climates. Fruit exposed to artificially controlled and naturally occurring minimum night temperatures above 70°F, combined with high day temperatures, had high Brix contents, low acid, and thin but green peels. Fruit exposed to minimum night temperatures below 60°, combined with moderate to cool day temperatures had both high Brix and acid and thicker but better colored peels. Cool temperatures in the late fall after hot summer and early fall conditions aided in thickening and coloring of peels of fruit which had already attained high Brix and early maturity.
