“…During the harvest period, there was a clear evolution of apple fruit maturation on the tree, characterized by reduction of firmness, starch content (increase of starch index) and TA, and an increase of SS content , as expected and already experimentally demonstrated for 'Gala' and 'Fuji' apples produced in Brazil (ARGENTA, 1993; ARGENTA, MONDARDO, 1994;ARGENTA et al, 1995;ARGENTA et al, 2010;SCOLARO et al, 2015).…”

“…The present study shows that at apple industry, the harvesting periods of 'Gala' and 'Fuji' apples extend for 12 and 13 weeks, respectively ( Figures 1F and 2F), being much longer than those experimentally indicated, even for apples produced in other countries (PLOTTO et al, 1995;SCOLARO et al, 2015). This greater extension of the commercial harvest period occurs because several technical means of orchard management are adopted to schedule the harvest of 'Gala' and 'Fuji' apples in Brazil.…”

“…The quality of apples (Malus domestica Borkhausen) can be negatively affected, both by excessive early and late harvest, especially when fruits are intended for long-term storage. In addition, the harvesting time also influences important characteristics that define the commercial value of fruits such as size and peel color (PLOTTO et al, 1995, STANGER et al, 2013, SCOLARO et al, 2015.…”

“…It is noteworthy that more than 95% of apples harvested are of only two cultivars, 'Gala' and 'Fuji' (PÉRÈS et al, 2009), the occurrence of unfavorable climatic conditions, particularly precipitation in the harvest time and insufficient availability of labor and infrastructure for harvesting, reception and handling at warehouse. The planting of apple trees in regions with different microclimates and the use of growth regulators to manage the dormancy release, flowering time and fruit maturation on the tree have been used to schedule the harvest time and to reduce the risk of harvesting immature and overripe apples (HAWERROTH et al, 2011;PETRI et al, 2011;SCOLARO et al, 2015).…”

A database of maturity and quality indices was built by analysis of 62,807 samples of 100 ‘Gala’ apples and 29,053 samples of 100 ‘Fuji’ apples at harvest, over 11 years (2005-2015) in an apple industry warehouse. Apple fruit were harvested in Fraiburgo (SC), São Joaquim (SC) and Vacaria (RS). Data on firmness, starch index (SI), soluble solid content (SS), titratable acidity (TA), size and grades (external appearance) of apple fruit were submitted to linear and nonlinear regression analyses. Each fruit was graded by analysis of external qualities (color and surface blemishes) following Brazilian legal standards. At apples industry, the harvest period extended from 3rd to 15th week of the year for ‘Gala’ and from 10th to 22nd week of the year for ‘Fuji’ apples, although approximately 70% of total production for ‘Gala’ and ‘Fuji’ apples was harvested in a period of 4 and 6 weeks, respectively. Average maturity of 11 years varied from the 1st to the last week of harvest as follows: ‘Gala’ apples: 17.9 to 14.2 pounds (firmness), 4.0 to 6.1 (SI), 12.2 to 13.1% (SS) and 5.7 to 3.9 meq 100 mL-1 (TA). ‘Fuji’ apples: 17.1 to 14.3 pounds (firmness), 3.9 to 6.4 (SI), 12.9 to 14.4% (SS), 6.2 to 3.8 meq 100 mL-1 (TA). Approximately 48% of ‘Gala’ samples and 45% of ‘Fuji’ samples had firmness higher than 17 and 16 pounds, respectively, intended for long term storage, while 6% of ‘Gala’ samples and 8.5% of ‘Fuji’ samples had firmness lower than 14 pounds, intended for marketing shortly after harvest. The frequency of apple samples graded as Extra, Cat1, Cat2, Cat3 and out of category were 6%, 32%, 34% and 6% for ‘Gala’ apples and 5%, 39%, 33%, 18%, 5% for ‘Fuji’ apples.

“…In addition, orchards formed by a reduced number of cultivars may also be more harmed in the case of adverse climatic events or outbreaks of pests and diseases (DENARDI et al, 2013). In the postharvest period, large amounts of fruits in a short period of time make it difficult to process and store in the packing house, and occasionally fruits are harvested at inappropriate maturity stage due to the scarcity of labor during commercial maturity (FIORAVANÇO et al, 2011;SCOLARO et al, 2015). In addition, making only two types of commercially available apple restricts the purchase options, an aspect that opposes current market trends, characterized by consumers willing to innovate and seeking diversity of options (FIORAVANÇO et al, 2011).…”

Abstract-This study aimed to evaluate the storage potential of SCS426 Venice apples under different storage technologies. Fruits were harvested in an experimental orchard located in Fraiburgo, SC and stored for up to eight and ten months in 2013 and 2014, respectively. Apples were treated or not with methylcyclopropene (1-MCP) and stored under air atmosphere (AA, 0.5±0.5 °C/RH 85±5%) or controlled atmosphere (CA; 1.5 kPa of O 2 and 1.5 kPa of CO 2 at 0.7±0.5 °C/RH of 93±3%). Fruits were evaluated every two months of storage, after one and seven days of shelf life (23 ± 0.3 °C/RH 93±3%). The storage period of 'SCS426 Venice' apples under AA without 1-MCP application should not extend beyond six months. Under this storage condition, fruits had higher incidence of decay, ethylene production and respiratory rates, higher skin degreening, lower flesh firmness, titratable acidity and soluble solids content than fruits stored under CA or AA with 1-MCP. 'SCS426 Venice' apples develop flesh browning and superficial scald after longterm storage. 'SCS426 Venice' apples under AA treated with 1-MCP or under CA (regardless of 1-MCP application) can be stored for more than eight months, keeping flesh firmness above 14 lb and low incidence of physiological disorders even after ten months of storage.
