Other claims from this paper (8)
- Intervention effect Bartlett pears picked early in the harvest season stored best in low O2 (0.5-1%) with elevated CO2 (5%) at 0°C.
- Intervention effect Pears harvested about 3 weeks later were intolerant to 2.5% CO2, with severe core and flesh browning in storage in less than 2 months.
- Intervention effect Fruits harvested at an intermediate date were mostly tolerant to elevated CO2.
- Recommendation The number of CO2-intolerant fruits would rule out commercial feasibility of CO2 storage for pears.
- Intervention effect Low O2 atmospheres (0.5-1%) caused no injury at any stage of maturity.
- Intervention effect Pears harvested late in the season were unsuited to prolonged storage regardless of atmospheric composition.
- Intervention effect Prolonged storage in controlled atmospheres did not cause undesirable flavor effects when pears were canned.
- Association Core and flesh browning associated with CO2 injury are distinct from browning and breakdown associated with excessive storage time and failure to ripen.
