ABSTRACT
Field experiment was conducted during 2011-12 at Fruit research station, Sangareddy to study the influence of flower enhancing plant growth regulators and fruit set improving chemicals on mango cv. Banganpalli. Trees applied with paclobutrazol (3ml.m-1 of canopy diameter) alone significantly reduced the vegetative growth in terms of minimum number of new flushes and internodal length compared to control trees. Paclobutrazol alone and in combinations with fruit set improving chemical significantly minimized the number of days taken for panicle initiation and increased the number of days taken for 50% and 100% flowering, duration of flowering when compares to control trees. Significantly highest fruits.tree-1 and yield was recorded in paclobutrazol (42.17 % over control) alone applied trees compare to control. Among the combination, maximum increase in yield over control was recorded in paclobutrazol application along with spermidine (63.11 %), NAA + spermidine (57.59 %), NAA + boron (60.03 %).
Key words: Vegetative growth, Panicle initiation, Paclobutrazol, Polyamines, Mango.
