Description Investigation on “Effect of paclobutrazol and summer pruning on growth, yield
and quality of apple cv. Red Delicious” was carried out in the experimental orchard of
Division of Fruit Science, Sher-e-Kashmir University of Agricultural Sciences and
Technology of Kashmir, Shalimar during the years 2011 and 2012. Above twenty five
years old trees of apple cv. Red Delicious with uniform vigour and health under uniform
cultural practices were selected for the experiment. The selected trees were sprayed with
paclobutrazol at (250 ppm, 500 ppm and 750 ppm) four weeks after full bloom followed
by summer pruning (I and II) eight and twelve weeks after full bloom, respectively.
Vegetative and phenological stages of the fruit trees were recorded and the fruit samples
with respect to size, weight, volume, colour change, firmness, organoleptic rating,
physiological loss in weight, spoilage, acid content, total soluble solids, sugars (total,
reducing and non-reducing sugars) and calcium content at regular interval of 10 days and
the last sample drawn at 30 days after storage were studied. Results revealed that trees treated with 750 ppm paclobutrazol + summer pruning (I and II) caused minimum
vegetative growth with increased fruit yield and return bloom. The fruit also retained
better quality characteristics under ambient storage conditions for a period of 30 days.
