| Abstract:
Initial low oxygen stress (ILOS) followed by ultra low oxygen (ULO) regimes was applied for many years on small quantities of ‘Red Delicious’ apples grown at 600 m altitude in Val di Non valley in Trento province (Italy). The positive results, obtained in more than six years commercial tests, in terms of superficial scald prevention and inhibition, were confirmed by the scientific evaluations done by the extension service technicians of the IASMA (Istituto Agrario San Michele all’Adige). In 2001 and 2002 the AVN Cooperative together with IASMA and FCE (Fruit Control Equipments) in active interaction decided to apply the operating procedures for ILOS +ULO on the CA storage rooms of ‘Red Delicious’ apples, for a total amount of fruits of more then 600.000 kg. During 6 months storage period of each year, fruits were evaluated at 2 weekly intervals during 15 days of regular storage at 20°C directly by the technician of the cooperative at site, while at same time other laboratory tests were carried out at IASMA. Results were always positive and well accepted by the Cooperative. All techniques involving no-chemical solutions are considered of primary importance for AVN, in accordance with their rigid integrated production protocol. It is therefore confirmed that ILOS+ULO is practically applicable in harmony with qualified technological solutions, validated by IASMA with their on-site extension service and laboratory evaluations and supported by customer’s satisfaction. No chemicals application, whenever possible is beneficial for consumer health. | |
