“…In the past, the semi-dwarfing rootstock M.7 was studied but its susceptibility to woolly aphid (Eriosoma lanigerum) (DENARDI et al, 2015), mainly due to its high level of suckering (FERREE;CARlSON, 1987), limited its adoption. Currently, the combination of 'Marubakaido' with an interstock of M.9 has given the tree size control necessary to increase planting density, but at medium densities (~1000 plantas ha -1 ).…”

Productive Performance of ‘Fuji’ Apple Trees on ‘Jm’ Series Rootstocks, in São Joaquim/Sc

et al. 2017

-Worldwide, research has developed new apple rootstocks that induce higher yields, pest resistance and adaptation to different climatic and soil conditions. Thus, the performance of these new rootstocks in the conditions of the main regions that grow apples should be investigated. The objective of this study was to evaluate the performance of 'Fuji' trees on different rootstocks of JM series and M.7 in the region of São Joaquim, SC. The experiment was performed from 2010 to 2015. Plant material consisted on the cultivar Fuji grafted on the rootstocks JM.2, JM.3, JM.5, JM.7, JM.8 and M.7, planted as single axis trees in the winter of 2002, and spaced at 5 x 1.5m. Trees were trained in a central-leader system and arranged in a randomized complete block design with four replicates. The number of fruits per tree, production per tree, yield, yield efficiency, fruit weigh, and trunk cross sectional area were evaluated. The results showed that the yield of 'Fuji' apple trees is greater with the rootstocks JM.3, JM.7, JM.8, and M.7. The rootstocks JM.2, JM.5, JM.7 and JM.8 induce similar vigor as M.7. The results also show that fruit weight is little affected by rootstock. Index terms: Malus domestica Borkh, yield, yield efficiency, fruit size. DESEMPENHO PRODUTIVO DE MACIEIRAS 'FUJI' EM PORTA-ENXERTOS DA SÉRIE 'JM', EM SÃO JOAQUIM/SCRESUMO -Centros de pesquisa internacionais têm desenvolvido novos porta-enxertos de macieira com maior produtividade, resistência a pragas e doenças e adaptação a diferentes condições edafoclimáticas. Então, o desempenho desses novos porta-enxertos nas condições das principais regiões produtoras deve ser pesquisado. O objetivo do trabalho foi avaliar o desempenho de macieiras 'Fuji' em porta-enxertos da série JM e M.7, na região de São Joaquim, SC. O experimento foi desenvolvido no período de 2010 a 2015. O material vegetal consistiu de plantas da cultivar Fuji enxertadas nos porta-enxertos JM.2, JM.3, JM.5, JM.7, JM.8 e M.7. As mudas de haste simples foram plantadas no inverno de 2002 em espaçamento de 5 x 1,5m. As plantas foram conduzidas no sistema de líder central. O delineamento experimental foi de casualização por blocos com quatro repetições. As variáveis analisadas foram produção por planta, número de frutos por planta, produtividade, eficiência produtiva e área da seção transversal do tronco. Os resultados obtidos mostraram que a produção de 'Fuji' foi maior com os porta-enxertos JM.3, JM.7, JM.8, e M.7. Os portaenxertos JM.2, JM.5, JM.7 e JM.8 induzem vigor semelhante a M.7. Os resultados também mostram que a massa de fruto é pouco influenciada pelo porta-enxerto. Termos para indexação: Malus domestica Borkh, produtividade, eficiência produtiva, tamanho de fruto.

“…Rootstock 'G. 814' is developed by the breeding program of CornellGeneva (Geneva ® series), that state the most complete rootstocks in relation to high-density systems and resistant to major pests and soil diseases of apple orchards in Brazil (DENARDI et al, 2015), and according to PASA et al (2016), the rootstock from this series looks very promising for the South region of Brazil. Thus, the micropropagation of adapted rootstocks to different apple cultivars is being widely studied today in order to obtain a commercial scale production and the possible replacement by new rootstocks, which requires the availability of large amount of propagation material.…”

Micropropagation of the new apple rootstock ‘G. 814’

et al. 2017

International breeding programs launched new genetic material of apple rootstocks that in addition to precocity and great yield are resistant to major diseases and soil pests encountered in the largest apple producing regions in Brazil. Given this, there is a necessity for vegetative propagation of these materials for study and possible replacement of existing rootstocks. The objective was to adapt a micropropagation protocol for new apple rootstock ‘G. 814’. In the multiplication phase were evaluated BAP concentrations: 0; 0.5; 1; 2 and 4mg L-1 and in the rooting phase were evaluated IBA concentrations: 0; 0.25; 0.50; 1; 1.5 and 2.5mg L-1. These new results demonstrated that this new rootstock selection can be propagated with this tissue culture adapted protocol. For the successful in vitro propagation of apple rootstock ‘G. 814’ it is indicated the use of 1mg L-1 BAP at multiplication phase and 1.5mg L-1 IBA at rooting phase.

“…Apple orchards in Brazil are concentrated in the southern region, mainly in the states of Santa Catarina and Rio Grande do Sul, which in 2016, accounted for roughly 96% of 1,049,251 tons produced in the country (IBGE, 2017). The plantations are composed of a combination of rootstocks M.9/Maruba and Maruba (DENARDI et al, 2015), and the latter is used mainly in the region of São Joaquim, Santa Catarina State, where soils are shallow and stony (POTTER et. Al., 2004).…”

“…Regarding agronomic characteristics, in addition to yield, the selection of new rootstocks seeks other features like balanced vigor, ease of propagation, resistance to the main pest and disease, absence of regrowth, good compatibility of grafting and scion support and efficient absorption of nutrients from the soil. Based on these and other parameters, rootstocks of American series Geneva ® present as the most complete among the rootstocks recently developed worldwide (FAZIO et al, 2013;DENARDI et al, 2015). In addition, the Japanese series JM, mainly JM.2, stands out for its high yield .…”

“…Consequently, several studies on these rootstocks have been conducted recently, focusing mainly on aspects of adaptation (DENARDI et al, 2013;DENARDI et al, 2015) and performance in different regions of cultivation of Brazil. Denardi et al (2015) suggest the use of rootstocks CG.213 and CG.202 for areas of good soil fertility, as potential options for the formation of new orchards with the cultivar 'Fuji' and rootstock CG.213 for 'Gala'. For low fertility soils, regardless of the cultivar, rootstock CG.210 is the most indicated.…”
