eGala?f, ?eRoyal Gala?f and ?eImperial Gala?f apples (Malus ?~ domestica Borkh.)
from commercial orchards in Southern Brazil were sprayed with 120 g ha-1 AVG
(aminoethoxyvinylglycine, ReTainTM) 4 weeks before the estimated commercial
harvest date in two growing seasons. Fruit were harvested every 5 to 7 days, starting
2-3 weeks before the estimated commercial harvest date. AVG-treated and
untreated fruit, harvested at the end of the optimum commercial maturity window
for long term storage (~75 N) were treated with 1 ?ÊL L-1 1-MCP (1-
methylcyclopropene, SmartFreshTM) on the day of harvest, and stored for 3, 5 or 7
months in air (0.5oC), or in controlled atmosphere (CA, 1.5 kPa O2 + 2.5 kPa CO2 at
0.5oC). Fruit maturity and quality were determined at harvest and after cold storage
plus 7 days at 20??C. Treatment with AVG delayed fruit ripening on the trees as
indicated by internal ethylene concentration, fruit firmness, starch index and peel
ground color. AVG treated fruit reached creamy-white peel background color and
firmness of approximately 75 N 8 to 18 days later than untreated fruit, depending on
cultivar and season. Pre-harvest treatment with AVG had little or no effect on rate
of fruit softening and incidence of senescent internal browning after storage when
fruit were harvested with firmness equivalent to that of control, regardless of
storage conditions and post-harvest treatment with 1-MCP. The highest fruit
firmness and the lowest incidence of senescent internal browning were observed on
CA stored fruit treated with 1-MCP, regardless of pre-harvest treatment with AVG.
Results indicate that possible differences in fruit quality after storage between AVGand
non-AVG-treated fruit are normally relative to differences in fruit maturity at
harvest. MenoseGala?f, ?eRoyal Gala?f and ?eImperial Gala?f apples (Malus ?~ domestica Borkh.)
