Abstract
Abstract Paclobutrazol was applied to soil around 5-year-old ‘Redhaven’ peach [ Prunus persica (L.) Batsch] trees at rates of 0, 1.1, 2.2, and 4.4 g a.i./tree in Dec. 1982. Trunk and shoot growth suppression in 1983 were related to application rate, but there was no treatment effect in 1984 or 1985. Yield and fruit size were not influenced in 1983 by treatment, but treated trees produced less fruit than control trees in 1985. Rate of defoliation was negatively related to concentration in 1984, and bloom development was positively related to concentration in 1985 following a single treatment in 1982. Chemical names used: β-[(4-chlorophenyl)methyl]-α-(1,1-dimethylethyl)-1 H -l,2,4-triazole-1-ethanol (paclobutrazol).
