Abstract

Low-volume sprinkler irrigation increased the mean trunk, mean scaffold limb, and mean canopy temperature 4.6°, 0.6°, and 0.8°C, respectively, higher than the nonirrigated trees of ‘Washington Navel’ orange (Citrus sinensis). Similar results were obtained with ‘Owari’ satsuma (Citrus unshiu) trees in that the mean trunk, mean scaffold limb, and mean canopy temperature was increased 3.9°, 1.7°, and 0.9°, respectively, higher than the nonirrigated trees. These results lend support that scaffold branch irrigation is effective as a method of freeze protection.
