Title: Quality of ´Fuji` Apples After Regular and Controlled Atmosphere Storage
Authors: S.R. Drake and D.C. Elfving
Abstract:
The postharvest quality of three strains (Naga-fu 2, 6 and 12) of 'Fuji' apples from two growing
locations was evaluated over four storage seasons.
Fruit quality was determined at harvest, after 90 days
of regular atmosphere (RA) storage and after 210 days of controlled atmosphere (CA) storage at 1% O2
& 1% CO2, 1% O2 & 3% CO2 and 1% O2 & 5% CO2. Strains of 'Fuji' apples had very little influence
on quality at harvest or after RA storage.
After CA storage some quality differences were evident
between strains, particularly, for red color development, which was greater in Naga-fu 2. Growing
location had an influence on quality parameters of 'Fuji' apples at harvest and after storage.
These quality differences determined for 'Fuji' apples between growing locations may offer an explanation of the
differences reported for 'Fuji' apple quality of the same strain.
Carbon dioxide level in the storage
atmosphere had a direct influence on fruit quality.
Fruit stored at 5% CO2 displayed more internal break
down at cavity development and less scald development than fruit stored at 1% and 3% CO2. 'Fuji'
apples stored well and maintained good quality at 3% CO2, which would be less costly to maintain than
1% CO2, the standard recommendation for the CA storage of 'Fuji' apples.
