Effect of harvest date on apple fruit quality and storage ability
Lithuanian Institute of Horticulture
Babtai, Kaunas distr., Lithuania
In 1997-2000 at the Lithuanian Institute of Horticulture the following
maturity parameters were evaluated to determine the optimum harvest date
of apple cv. ‘Auksis’ - fruit weight, blush, firmness, soluble solids, and
starch conversion stage. The apples for storage were harvested 5 times at
weekly intervals before, during, and after the estimated optimum harvest
date. The maturity index (F/RS) was calculated at each picking time.
Quality changes, presence of storage disorders, mass losses, and sensory
valuation were employed to estimate the optimum harvest date. It was found
that apples picked too early tend to lose their mass and flesh firmness
faster during storage, and had a lower content of soluble solids before
and after storage. Apples picked too late showed more rot during storage.
At the end of the storage period apples picked when the maturity index
value was 0.15-0.20 were of the best quality.
