An eight year old 'Roundel' apricot trees growing under low density planting system were treated with paclobutrazol as a soil drench at 0 (control), 5, 10 and 12g/tree in the year 2010 and 2011. In this experiment, paclobutrazol significantly retarded the shoot growth, shoot diameter and TTCSA during the course of investigation. The minimum shoot growth was observed when 10g paclobutrazol was applied/ plant as compared to rest of the treatments. As far as number of fruits/plant and yield was concerned, application of 10g paclobutrazol significantly recorded the highest in both the years as compared to rest of the treatments. The effect of paclobutrazol on fruit L/D ratio, seed weight, acidity and total sugars were non-significant. The results of the present study revealed that paclobutrazol significantly reduced the vegetative growth of plants, enhanced the fruit quality and increased the yield during both the years of study.
