STORAGE ABILITY OF VEGETABLES AS INFLUENCED BY WEATHER CONDITIONS BEFORE HARVESTING
Storage losses of vegetables comprise both weight and trim losses. Results achieved from replicated experiments, that had been carried out in different years, often showed rather wide deviations from each other, though environmental conditions during plant growth, and climatic conditions of the storage rooms had been comparable and reproduceable. Deviating results therefore only can be attributed to differences in the physiological stage of maturity of the plant, or to differences in weather conditions before harvesting. Multiple stepwise regression analysis was to investigate the quantifiable effect of weather conditions present during the last 20 days preceding harvesting on the storage behaviour of chinese cabbage and carrots.
- Weight losses of carrots mainly were influenced by the amount of rainfall, and by the relative humidity before harvesting. Apart from the amount of rainfall, it were temperature factors (highly correlated to humidity) that took some effect on weight losses of chinese cabbage.
- Trim loss of chinese cabbage mainly was influenced by the sunshine duration during growth.
- The salable amount of chinese cabbage mainly was influenced by the sunshine duration during growth.
