Effect of plant growth regulator and other chemicals on floral malformation, flowering, fruit set, yield and fruit quality of mango cv. Amrapali






Biological Memoirs 24(1): 19-24, June

Effect of plant growth regulator and other chemicals on floral malformation, flowering, fruit set, yield and fruit quality of mango cv. Amrapali

Effect of naphthalene acetic acid (NAA - 200 ppm), cobalt sulphate (CoSO4-1000 ppm) nickel sulphate (NiSO4-400 ppm), silver nitrate (AgNO3-400 ppm) and potassium metabisulphate (K2S2O5-400 ppm) were evaluated against the incidence of floral malformation and other associated attributes. Minimum incidence of malformation was observed in the double spray of NAA (0.90%), single spray of CoSO4 (1.63%) and K2S2O5 (5.68%) as compared to control (11.70%). Flowering, fruit set and yield were more in double spray of NAA and single spray of CoSO4. Some of the chemicals delayed the flower bud initiation and the delay was maximum (7-8 days) in CoSO4 treated plants. Substantial improvement in fruit quality in terms of firmness, TSS, sugar content and alpha-amylase were also noticed by the application of most of these chemicals.
