| English abstract | 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 |
| Portuguese abstract | Este trabalho objetivou testar diferentes doses de Paclobutrazol (PBZ), ethephon e nitrato de cálcio na indução do florescimento e na produção da mangueira (Mangifera indica L.) cv. Tommy Atkins, localizada no pomar didático da ESAM em Mossoró-RN, no ano de 1999/2000. O delineamento experimental utilizado foi em blocos casualizados, no esquema fatorial 2x2x3, assim distribuídos: T1 1000 mg.L-1 de PBZ+ 2% de nitrato de cálcio; T2 1000 mg.L-1 de PBZ + 2% de nitrato de cálcio + 1,0 mL.L-1 de ethephon; T3 1000 mg.L-1 de PBZ + 2% de nitrato de cálcio + 3,0 mL.L-1 de ethephon; T4 1000 mg. L-1 de PBZ + 3% de nitrato de cálcio; T5 1000 mg.L-1 de PBZ + 3% de nitrato de cálcio + 1,0 mL.L-1 de ethephon; T6 1000 mg.L-1 de PBZ + 3% de nitrato de cálcio + 3,0 mL.L-1 de ethephon ; T7 1500 mg.L-1 de PBZ + 2% de nitrato de cálcio; T8 1500 mg.L-1 de PBZ + 2% de nitrato de cálcio + 1,0 mL.L-1 de ethephon; T9 1500 mg.L-1 de PBZ + 2% de nitrato de cálcio + 3,0 mL.L-1 de ethephon; T10 1500 mg.L-1 de PBZ+ 3% de nitrato de cálcio; T11 1500 mg.L-1 de PBZ + 3% de nitrato de cálcio + 1,0 mL.L-1 de ethephon.L; T12 1500 mg.L-1 de PBZ + 3% de nitrato de cálcio + 3,0 mL.L-1 de ethephon, com 4 repetições. A mangueira teve um maior florescimento (81,75%) com 2% de nitrato de cálcio e 1500 mg. L-1 de PBZ, o número de frutos por planta teve seu maior valor (86 frutos) com 3% de nitrato de cálcio e 1500 mg L-1 de PBZ e o peso do fruto foi maior (425,5g) na dosagem de 3mL.L-1 de ethephon. Os produtos aplicados não diferenciaram entre si em relação à produção |
