Biochemical Changes in Fruit Quality Through Paclobutrazol Application on Acid Lime (Citrus aurantifolia Swingle)

Abstract

Field experiment was conducted to find out the impact of soil applied paclobutrazol on fruit quality of five year old acid lime trees. The experiment was conducted in a randomized block design with four replications. Four concentrations of paclobutrazol viz., 1.25, 2.50, 3.75, and 5.00 g a.i/tree were applied as soil drench before flower bud formation during main season of the year 2008 – 2009. The results of the experiment revealed that the titrable acidity, ascorbic acid and total sugars content of fruits were improved by soil application of paclobutrazol. Soil application of paclobutrazol 5.00 g a.i / tree recorded higher titrable acid content in the main (9.59 and 8.91 per cent) and off season (9.38 and 8.75 per cent) and higher total sugars (reducing and non-reducing) in the main (1.15 and 1.13 per cent) and off season (1.13 and 1.12 per cent) during the year 2008 - 09 and 2009 – 10, respectively, whereas paclobutrazol 2.50 g a.i/tree recorded higher ascorbic acid content in the main (31.2 and 29.9 mg/100g) and off season (30.7 and 29.5 mg/100g) during the year 2008 - 09 and 2009 – 10, respectively.
