Abstract
SummarySprays of paclobutrazol at 500 mg l−1 on 12-week old ‘Red Delicious’ apple seedlings significantly reduced vegetative growth and increased root:shoot ratios. Root dry weight, relative growth rate, net assimilation rate and leaf area ratio were not affected. The reduction in shoot growth was associated with a redistribution of 14C-labelled assimilates in the plant. The response was greatest one day after treatment but was still evident 14 days later and to a lesser extent 28 days after treatment.
