Abstract
|
|
|
Experiments were carried out to clarify changes of intercellular gas composition, respiration and ethylene evolution by controlled external atmospheric pressure and external gas composition on apples. Jonathan apples, harvested 25, in September and Rolls apples, harvested 25, in October, 1971 and 1972, were used.
Results obtained were as follows:
1. Intercellular gas volumes were proportionally changed by the given pressure, and the given pressure remarkably affected internal gas composition and volume of apples.
As intercellular gas volumes were reached in their equilibrium within 5 min. after treatment, the internal atmospheric conditions became constant rapidly.
2. The increase of internal CO₂ production was co-related with an amount of internal O₂ consumption, therefore, the decreasing period of internal O₂ consumption was eqalled to the peried of climacteric rise in respiration.
3. The increasing of CO₂ production followed evolution of, C₂H₄ and this phenomenon on SAP part was subsequent to NAP part
4. In sub-atmospheric storage, CA effect was also obtained by control of low O₂ and high
CO₂ concentration.
