Abstract

The experiment was conducted to investigate the effect of some bioregulators applied to improve plum yields and fruit quality.
The field experiment was designed in 4 treatments, disposed linearly and 4 replications with the plum tree cultivar as factor A, bioregulator products application as factor B and the timing of application as factor C. Foliar application of bioregulators has induced an increased plum yield of 25% with the Stanley cultivar (treatment with Paclobutrazol) and 15% with the Tuleu gras cultivar (treatment with prohexadione calcium) versus control.
The bioregulator treatment (2-cloroethylphosphonic acid) had a good effect on plum fruit quality (means weight, colour and chemical composition) and prevented alternate bearing on Stanley and Tuleu gras cultivars.
