“…Estudos com outras espécies, como macieira (Malus domestica Borkh) e pereira (Pyrus communis L.) corroboram com o resultado apresentado, no caso destas espécies, houve redução do comprimento do ramo (Hawerroth & Petri, 2014;Pasa et al, 2014). Em macieira é relatada uma redução do crescimento dos ramos da ordem de 19,3%, 26,5% e 28,9%, dependendo do ano e com aplicação de 330 mg L -1 de ProCa (Hawerroth & Petri, 2014).…”

“…Dentre as alternativas para o controle de crescimento vegetativo de plantas, o uso de reguladores de crescimento se apresenta como uma alternativa promissora (Black, 2004;Hawerroth & Petri, 2014;Pasa & Einhorn, 2014;Rezazadeh & Harkess, 2015), sendo relatada por alguns autores a supressão do crescimento de mudas de morangueiro com a aplicação de proexadione cálcio (ProCa -cálcio 3-óxido-4-propionil-5-oxo-3-ciclohexano carboxilato) (Black, 2004;Reekie et al, 2005).…”

“…however, due to its high vigor this rootstock is not well suited to plantings at higher densities. Increasing planting density is one of the most important factors affecting yield (PETRI et al, 2011) and profitability (KREUZ et al, 2006) of apple orchards, but its efficiency depends on suitable techniques to control tree size, like the right choice of rootstock (PASA; EINhORN, 2014).…”

“…Therefore, they are potential alternatives to 'Marubakaido' and 'Marubakaido/M.9' for plantings at higher densities. Increasing planting density is one of the most important factors to achieve greater yield of apple orchards (PETRI et al, 2011), but depends on efficient techniques to control tree size (PASA; EINhORN; 2014). In light of this, the rootstocks JM.7 and JM.8 show great potential for increasing the planting density of apple orchards in the region of São Joaquim.…”

-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.

“…Previous studies have demonstrated that ProCa controls shoot growth of different pear (Elfving et al, 2003;Smit et al, 2005;Asín et al, 2007;Hawerroth et al, 2012;Einhorn et al, 2014;Pasa and Einhorn, 2014) and apple (Duyvelshoff and Cline, 2013) cultivars with varied influences on other horticultural traits. Sugar et al (2004) reported smaller fruit size of 'William's', but not 'Bosc', and 'Red Anjou' in the year of ProCa application, while 'D'Anjou' fruit size was affected in just one trial; 'Bosc' return bloom and yields were markedly reduced the year following application, but 'William's' and 'D'Anjou' were not similarly affected.…”

The aim of this study was to evaluate the effects of prohexadione calcium (PCa) on vegetative growth and production of ‘Carrick’, ‘Packham’s’ and ‘William’s’ pear. The trial was performed at the experimental field of the Federal University of Pelotas, Capão do Leão, RS, Brazil (31º 52’ 00" S; 52º 21’ 24" W), during the growing seasons of 2011 and 2012. Treatments were applied to single-tree replications in a randomized complete block design with four replications as follows: Control (unsprayed), PCa (PCa - 750 g ha-1 i.a.). The application was split in four (187,5g ha-1 a.i. each) and three timings (250g ha-1 a.i. each) in the 2011 and 2012 growing seasons, respectively. The assessed parameters were: shoot length, trunk cross sectional area (TCSA) increment, number of nodes, internode length, pruning weight, number of fruits, average fruit weight, production per tree and return bloom. It was possible to conclude that application of PCa at 750 g. ha-1 a.i satisfactorily controls shoot growth through the reduction of internode length of ‘Carrick’, ‘Packham’s’ and ‘William’s’ pears. Besides, it was observed that return bloom is not negatively affected by PCa. So, this plant growth regulator is a potential management tool to reduce shoot growth and the need for pruning in pear orchards.
