MENDONCA, VANDER et al. FLOWERING AND FRUTIFICATION OF MANGO WITH USE OF PACLOBUTRAZOL, ETHEPHON AND CALCIUM NITRATE . Rev. Bras. Frutic. [online]. 2001, vol.23, n.2, pp.265-269. ISSN 0100-2945.  https://doi.org/10.1590/S0100-29452001000200012.

This work had the objective of testing distinct concentrations of Paclobutrazol, ethephon and calcium nitrate to induce flowering in the production of the mango cv. Tommy Atkins, located in the didactic orchard of the Superior School of Agriculture of Mossoró. The experiment was developped in the year of 1999/2000. A randomized experimental block design, was used in the factorial scheme 2x2x3; distributed in: T1 1000 mg.L-1 of PBZ+ 2% calcium nitrate; T2 1000 mg.L-1 of PBZ + 2% calcium nitrate + 1,0 mL.L-1 of ethephon; T3 1000 mg.L-1 of PBZ + 2% calcium nitrate + 3,0 mL.L-1 of ethephon; T4 1000 mg.L-1 of PBZ + 3% calcium nitrate; T5 1000 mg.L-1 of PBZ + 3% calcium nitrate + 1,0 mL.L-1 of ethephon; T6 1000 mg.L-1 of PBZ + 3% calcium nitrate + 3,0 mL.L-1 of ethephon; T7 1500 mg.L-1 of PBZ + 2% calcium nitrate; T8 1500 mg.L-1 of PBZ + 2% calcium nitrate + 1,0 mL.L-1 of ethephon; T9 1500 mg.L-1 of PBZ.L + 2% calcium nitrate + 3,0 mL.L-1 of ethephon; T10 1500 mg.L-1 of PBZ + 3% calcium nitrate, T11 1500 mg.L-1 of PBZ + 3% calcium nitrate + 1,0 mL.L-1 of ethephon; T12 1500 mg.L-1 of PBZ + 3% calcium nitrate + 3,0 mL.L-1 of ethephon, with 4 replications. The mango had a larger flowering (81.75% of fruits ) with 2% calcium nitrate and 1500 mg. L-1 of PBZ, the number of fruits per plant was the highest (86 fruits) with 3% calcium nitrate and 1500 mg L-1 of PBZ and the weight of the fruit was the heaviest (425,5g/fruit ) in the dosage of 3,0 mL.L-1 of ethephon. The applied products were not different among themselves in relation to the production.
