Abstract in Portuguese
Este trabalho foi realizado no pomar da Escola Superior de Agricultura Luiz de Queiroz, da Universidade de São Paulo, com o objetivo de verificar a influência da combinação copa x porta-enxerto na produtividade da mangueira. A altura e diâmetro da copa, foram medidos em 1981, e ainda foram observados o número de panículas e o número de frutos durante os anos de 1981 a 1983 em 210 plantas que no início do experimento estavam com 15 anos de idade. As plantas têm como porta- enxertos as variedades Extrema, Espada, Oliveira Neto, Carlota, Bourbon, Coco e Pahiri e como copa as variedades Extrema, Pahiri, Imperial, Oliveira Neto, Carlota e Bourbon. Os dados foram analisados estatisticamente segundo o programa LSMLGP (Least squares, Maximum Likelihood General Purpose) de Harvey. As copas mais produtivas são Carlota e Oliveira Neto, que também revelaram-se como os melhores porta-enxertos para a copa de Carlota, com índice de frutificação de 6,3 e 6,4 frutos/m2 de copa, respectivamente. A produção de frutos nos anos de 1981 e 1983 foi influenciado pela variedade de copa, enquanto que no ano de 1982, foi influenciado pela variedade do porta­enxerto. A interação copa x porta-enxerto não influenciou na produção.
Title in English
Influence of rootstock and scion on mango (Mangifera indica L.) productivity
Abstract in English
This work was conducted in the Escola Superior de Agricultura Luiz de Queiroz orchard and was undertaken to investigate the influence of the combination of scion x rootstock in the mango tree productivity. The trees high and scion diameter were measured once in 1981 and the number of panicles and the number of fruits were determinate from 1981 to 1983, using 210 trees with 15 years old at the beginning of the experiment. The Extrema, Espada, Oliveira Neto, Carlota, Bourbon, Coco and Pahiri varieties were used as rootstock and the varieties Extrema, Pahiri, Imperial, Oliveira Neto, Carlota and Bourbon were utilized as scion. The results were statistically analyzed by the LSMLGP Harvey program (Least, Maximum Likelihood General Purpose). The scion of Carlota and Oliveira Neto varieties showed the highest productivity, and were also the best rootstock for the Carlota scion, that showed a frutification rat of 6.3 to 6.4 fruits/m2 respectively. The fruit productions in the 1981 and 1983 varied according to scion variety, while in 1982 the fruit productions varied according to rootstock. The interaction scion x rootstock did not have any influence on fruit production, as statistically demonstrated.
