dc.description.abstractThe present study entitled “Studies on hormonal regulation of growth, yield and fruit quality of persimmon (Diospyros kaki L.)” was carried out in the experimental block of the Department of Fruit Science, Dr Y S Parmar University of Horticulture and Forestry, Nauni - Solan (Himachal Pradesh) during the year 2022-23. The experiment was laid out in Randomized Block Design consisting of thirteen treatments replicated thrice. The plant bio-regulators and bio-stimulant were applied at 6 weeks before full bloom, 1 week before full bloom, and 30 days after full bloom. The plant bio-regulators and bio-stimulant treatments were T1: GA3 20 ppm, T2: GA3 40 ppm, T3: GA3 60 ppm, T4: Benzyladenine 20 ppm, T5: Benzyladenine 40 ppm, T6: Benzyladenine 60 ppm, T7: Brassinosteroid 0.1 ppm, T8: Brassinosteroid 0.01 ppm, T9: Brassinosteroid 0.001 ppm, T10: Bio-stimulant 1 mL/L, T11: Bio-stimulant 2 mL/L, T12: Bio-stimulant 3 mL/L, and T13: Control (water spray). The results from the present investigation revealed that plant bio-regulators and bio-stimulant significantly influenced plant growth, yield, fruit quality, and leaf hormone content at different phenological stages of persimmon cv. Hachiya. Among various treatments significantly better fruit quality attributes namely, fruit weight, yield, ascorbic acid content, TSS, total sugars, non-reducing sugars along with photosynthesis rate were recorded with the foliar application of 40 ppm GA3 (T2). Application of 60 ppm BA (T6) had the most significant influence on annual shoot extension, fruit size, volume, stomatal conductance and transpiration rate. All the treatments also had a positive influence on the leaf hormone content of persimmon at different phenological stages with treatments T3 (60 ppm GA3), T6 (60 ppm BA), and T7 (0.1 ppm brassinosteroid) performing better than others.
