EFFECT OF PROMALIN AND PACLOBUTRAZOL APPLICATIONON GROWTH AND FRUITING OF HIGH DENSITY APPLE TREES
Horticultural Research Institute, Agricultural Research Center
Abstract
Effect of promalin* and paclobutrazol** were studied on growth and yield of Anna apple tress in meadow orchard during two seasons (1996-1997) and (1997-1998) . Vegetative growth was stimulated, when promalin applied at beginning of September with concentrations 200, 400 and 600 ppm.
The application of 1000 ppm paclobutrazol (PBZ) at benginning of October on the trees treated with different concentration of promalin inhibited shoot growth, and increased spur number and increased the yield per tree Paclobutrazol increased the percentrage of total carbohydrate in leaves. Best results were obtained from treatments of 600 ppm promalin followed by 1000 ppm PBZ.
The treatment of PBZ alone increased weight, size and color of the fruits.
