Vegetative Growth, Yield and Fruit Quality of ‘Gala’ Apple Treated with Regalis (Prohexadione-Ca)
The trial was conducted in a ‘Gala’/M9 orchard and the experiment was designed as a randomized block comprising four treatments (application of Prohexadione-Ca: 125 mg-l, 250 mg-l, 2 x 125 mg-l, and control - without growth regulator). Experiments have been carried out for 2 years (2003, 2004). Application of Regalis reduced trunk cross-sectional area increment, and cumulative extension shoot growth. The effect increasing with concentration, and a greater inhibition was obtained when the trees were sprayed two times. Compared to control, return bloom of Regalis-treated trees was not affected. No negative effects of treatment with Regalis on yield per tree were observed, but some reduction of average fruit weight was found.
