“…The fruit had an average weight of 108.4 and 115.6 g for 'Maxi Gala' and 'Fuji Suprema' , respectively, without treatment effect, which was also verified for yield (24.7 and 29.1 t•ha -1 , respectively) (data not shown). Apple fruit presenting Ca deficiency have shown higher bitter pit incidence in the postharvest period (Corrêa et al 2017;Miqueloto et al 2018), and it can get worse when fruit present high Mg, N and K levels and its relationship with Ca (Amarante et al 2020), as the ones observed in the present study. On the other hand, fruit presenting high Ca concentrations often show greater pulp firmness, both at harvest and during storage (Fallahi et al 2010).…”

The aim of this study was to evaluate the effect of new Ca sources sprayed on 'Fuji Suprema' and 'Maxi Gala' apple trees on nutrient levels in leaves and fruit, as well as on fruit ripening features and quality at harvest time and after cold storage. Experiments were carried out in a commercial orchard planted with 'Fuji Suprema' and 'Maxi Gala' apple trees in Caçador, Santa Catarina state, Brazil.Application of different Ca sources and untreated trees were evaluated in each experiment. Fruit were harvested at two different ripening stages and analyzed based on the following variables: fruit ripening at harvest time, as well as fruit quality and incidence of physiological disorders after 210-day storage at 1 °C. Calcium applications did not change Ca levels in the leaves and of the whole fruit. Calcium levels in fruit peel increased in cultivars Maxi Gala and Fuji Suprema due to leaf Ca applications. 'Maxi Gala' apples recorded higher postharvest incidence of physiological disorders, such as greater loss of fruit firmness than 'Fuji Suprema' apples (Due to 1-methylcyclopropene [1-MCP] application on 'Fuji Suprema' apples). Calcium applications did not change fruit maturation (starch index and pulp firmness) or apple pulp firmness preservation in both cultivars, although they reduced the incidence of bitter pit disorder in 'Maxi Gala' apples. The new sources of Ca tested did not increase Ca contents, nor did they reduced the risk for physiological disorder compared to the standard CaCl 2 treatment that has been commercially used for decades as the main Ca fertilizer.

“…Miqueloto et al (2011) concluíram que a relação K/Ca foi, dentre os atributos minerais, o melhor indicativo para discriminar frutos com a presença de "bitter pit", especialmente para maçãs 'Catarina'. Em maçãs 'Gala' e 'Fuji', outros autores também já definiram essa relação como a mais indicada para discriminar frutos com predisposição à ocorrência de distúrbios fisiológicos (AMARANTE; CHAVES;ERNANI, 2006;CORRÊA et al, 2017).Conforme os autoresSuzuki (1994); Nachtigal; Freire (1998);Katsurayama; Tsuchiya; Boneti (2001); Amarante et al (2012); Santos (2015) evidenciam que a presença de distúrbios está diretamente relacionada com a baixa concentração de Ca associada a elevados teores de K, Mg e N, sendo suas correlações evidências diretas do desequilíbrio mineral dos frutos. Variação semelhante foi observada quando analisou-se a relação (K+Mg)/Ca nas diferentes cultivares.…”
