Crosstalk effect of brassinosteroids and gibberelic acid affects plant phenology, yield and fruit quality traits in sugar apple (Annona squamosa L.) cv. Balanagar

Abstract

Present experiment was carried out to investigate the crosstalk effects of brassinosteroids (BRs) and GA3 on plant parameters, yield characters and composition of sugar apple fruits. Among different treatment combinations comprising brassinosteroids and gibberellic acid, T5 treatment consisting (BRs @ 0.5ppm + GA3 @ 25 ppm) Give value of important parameters such as foliar spray of BRs (0.5ppm) + GA3 (25ppm) significantly maximized the rootstock growth with value (4.81%), scion girth (5.75%), plant height (6.02%) canopy volume, flower number (265.33), flower retention (67.69%), flower size, no of fruits per plant, fruit retention, no of stone fruits, yield per plant (18.51kg/plant).
