“…Apples (Malus domestica Borkh) are the most popular fruit grown in regions of temperate climate in terms of cultivated area and volume produced (Stanger et al, 2017). However, due to the high production and the short period the fruits naturally remain at the correct maturation stage (Brackmann et al, 2015a(Brackmann et al, , 2015b, the adoption of technologies to increase the harvest period is necessary, rationalizing the use of labor and allowing the fruits to be harvested at the ideal point (Scolaro et al, 2015;Soethe et al, 2019).
