Comparison of Metabolic Inhibitors, Film-Forming Antitranspirants, and Microjet Irrigation for Water Use Efficiency of Rabbiteye Blueberries

摘要

Two metabolic inhibitors abscisic acid (ABA) and phenyl mercuric acetate (PMA), antitranspirant materials Clear Spray (CS) and Vapor Gard (VG), and microjet irrigation system were used on two rabbiteye blueberries cv. 'Tifblue' and 'Woodard'. The objective of this experiment was to study the effects of using the above materials in increasing yield, improving quality and water use efficiency of blueberry. Application of ABA, PMA, CS and VG, separately or in combination, with the microjet irrigation system significantly increased the water use efficiency of rabbiteye blueberries.
