“…In the orchards of Vacaria, the K/Ca ratio presented a higher PDR than the Ca content and the Mg/Ca ratio (Table 2), which partly coincides with the results found by Neuwald et al (2008). Th e higher PDR coeffi cient for the K/Ca ratio may be due especially to the Ca content, which presented a higher canonical correlation coefficient (r) ( Table 2).…”

“…Hunsche et al (2003) verifi ed that the fl esh browning disorder in 'Fuji' apples stored under CA is associated with K contents, where the lower the content in the fruit fl esh, the higher the incidence of fl esh browning disorder. However, in 'Braeburn' apples, Neuwald et al (2008) observed a positive correlation between the K contents and flesh browning disorder. However, in this test, the nutrient did not present a correlation with the fl esh browning disorder in the orchards under study.…”

“…The fruit with and without flesh browning did not present diff erent K contents as well as K/Ca and (K + Mg)/Ca nutritional ratios (Table 1). However, Neuwald et al (2008) observed in 'Braeburn' apples a strict connection between the K concentration in the fl esh and the incidence of fl esh browning disorder. Similarly, Andziak and Tomala (2004) observed a higher occurrence of fl esh browning disorder in 'Janagold' apples with a high K/Ca ratio.…”

“…High K contents have also been associated with flesh browning disorder in 'Braeburn' apples (Neuwald et al 2008). The nutrient Mg may also have some connection with physiological disorders in fruit, because it competes directly with Ca in the plasma membrane binding sites, although, like K, it does not perform the same function as Ca (Freitas et al 2010).…”

“…No entanto, estes aspectos ainda precisam ser mais bem estudados (JAMES;JOBLING, 2009). O K é um nutriente antagonista ao Ca (NEUWALD et al, 2008), cujo efeito é devido a uma competição com o Ca por sítios de ligação na membrana plasmática (JAMES; JOBLING, 2009).…”

RESUMO -O objetivo deste trabalho foi avaliar os efeitos de três porta-enxertos sobre a composição mineral em maçãs 'Fuji', bem como a qualidade e incidência de degenerescência de polpa dos frutos, armazenados em duas condições de atmosfera controlada (AC). Frutos provenientes de árvores com três porta-enxertos (MM-106, Marubakaido e Marubakaido com filtro M-9) provenientes de São Joaquim -SC foram armazenados por oito meses em duas condições de AC (1,2 kPa O 2 + <0,5 kPa CO 2 e 1,2 kPa O 2 + 2,0 kPa CO 2 ). Sete dias após a retirada das câmaras, determinaram-se: taxa de produção de etileno, cor da epiderme (h°), força para a penetração da polpa, acidez titulável, sólidos solúveis, incidência e severidade de degenerescência de polpa e composição mineral (Ca, Mg e K) na polpa dos frutos. Entre condições de AC, os frutos armazenados com 2,0 kPa de CO 2 apresentaram um retardo no amadurecimento se comparados aos frutos armazenados nas condições de <0,5 kPa de CO 2 . Quanto aos diferentes porta-enxertos, na condição de armazenamento com 2,0 kPa CO 2, os frutos de plantas com Marubakaido e Marubakaido com filtro-M9 apresentaram maior incidência de degenerescência de polpa se comparados aos frutos de plantas com MM-106, que apresentaram maiores teores de Ca e menores teores de K, e menor relação K/Ca. A qualidade de maçãs 'Fuji' é influenciada principalmente pela condição de armazenamento em AC e muito pouco pelo tipo de porta-enxerto. Plantas enxertadas com MM-106 proporcionam frutos com menor predisposição à degenerescência de polpa, que por sua vez está relacionada à composição mineral do fruto.

MINERAL COMPOSITION, QUALITY AND INTERNAL BREAKDOWN OF 'FUJI' APPLES IN DIFFERENT ROOTSTOCKS DURING CONTROLLED ATMOSPHERE STORAGEABSTRACT -This study was carried out to evaluate the effects of three rootstocks on mineral composition of 'Fuji' apples, as well as on their, quality and incidence of internal breakdown in two controlled atmosphere (CA) conditions. Fruits harvested from trees with different rootstocks (MM-106, Marubakaido and Marubakaido with M-9 interstock) were stored for eight months in two CA conditions (1.2kPa of O 2 + <0.5kPa of CO 2 and 1.2kPa of O 2 + 2.0kPa of CO 2 ). Seven days after removall from CA storage, fruits were assessed for ethylene production rate, skin color (h°), flesh penetration force, titratable acidity, soluble solids content, incidence and severity of internal breakdown and mineral composition (Ca, Mg and K) in the fruit pulp. Among the CA conditions, fruits stored in 2 kPa CO 2 showed delayed in the ripening compared to fruits stored in <0.5 kPa CO 2 . When comparing rootstocks, fruits harvested from trees on Marubakaido and Marubakaido with M-9 interstock and then stored in 2.0 kPa of CO 2 showed higher incidence of internal breakdown than fruits harvested from trees on MM-106 rootstock. Fruits harvested from trees on MM-106 rootstock had higher Ca and lower K conte...
