摘要

Mature slender spindle 'Jonagold'/M.9 apple (Malus x domestica Borkh.) trees were thinned using 10 mg l(-1) 1-naphthaleneacetic acid (NAA) or 100 mg l(-1) 6-benzyladenine (BA) and an axial fail sprayer at a spray volume of 1,500 l ha(-1) applied to the whole canopy, or with smaller volumes, where only the upper half of each canopy was sprayed. Partial spray applications of NAA or BA (at 1,000 l ha(-1), 750 l ha(-1), or 500 l ha(-1)) to the upper half of the trees did not cause any reduction in final fruit numbers on the upper half, or oil the lower half of each tree. When the whole tree was sprayed to run-off with the same thinning agent, or at 1,500 l ha(-1), successful thinning oil both file upper and lower parts of the canopy occurred. Good spray coverage (from 51% to 77%) was also observed oil leaves at all canopy positions measured, when whole trees were sprayed at 1,500 l ha(-1). The development of an innovative crop load regulation strategy was an objective of the ISAFRUIT Smartfruit Project.
