摘要：

The study was aimed to assess the effect of different levels of paclobutrazol and summer pruning on fruit quality of apple cv. 'Red Delicious'. The experiment was conducted at SKUAST-K, Shalimar (J&K) during 2012 and 2013 on apple trees of > 15 years age, spaced at 5.49 x 5.49 m distance. The experiment was laid in a completely randomized block design with paclobutrazol spray tested at 3 concentrations (250, 500 and 750 ppm) and summer pruning at 2 timings (8 and 12 weeks after full bloom) and their combinations. Highest yield of 101.0 kg tree(-1) was obtained in treatment 750 ppm paclobutrazol + 2 summer prunings in comparison to control. In addition, it significantly improved fruit size (53.15 cm), weight (188.19 g), volume (188.12 cm(3)), colour change (3.40 score), firmness (11.98 kg cm(-2)), organoleptic rating in terms of taste (3.14 score), texture (3.24 score), flavour (3.12 score) and total soluble solids (14.47oB) whereas acidity (0.23%) was reduced in comparison to control and other treatments during both the years.
