Abstract: CH201/FRED® is a novel red-blush pear cultivar with long-term storage potential and a prolonged shelf life. However, it is prone to controlled atmosphere (CA)-related disorders, particularly cavities. This study explored the impact of the balance between vegetative growth and crop load on the development of CA-related disorders during storage. Treatments involving the removal of two-thirds of floral bouquets (Fl_Th) and the shortening of branches by two-thirds (Pr) at the bud stage (late balloon stage) promoted the growth of 1-year-old shoots, which correlated with an increased incidence of cavities and reduced calcium levels in the pears. The Fl_Th treatment resulted in larger fruits with a higher total soluble solid content, a greater force required to puncture the skin and flesh, and a higher incidence of cavities than the Pr treatment. These findings demonstrate that both crop load and the leaf area-to-crop load ratio significantly influence the susceptibility of CH201/FRED® pears to CA-related disorders during storage.
