Onions of the variety Granex 33 were placed in low humidity, warm air storage for a minimum of 15 weeks and then examined for weight loss, pungency, soluble solids, and disease presence. They were compared with onions held in cold and CA storage. Temperature and relative humidity of the air in the low humidity, warm air storage established levels as generated by a heat-pump-dehumidifier with means 30 degrees C to 34 degrees C and 29% to 36% R.H. over years, there being a 0.2 degrees C to 0.6 degrees C and 0.1% to 0.6% R.H. differential between intake and exhaust conditions. Low humidity, warm air storage proved suitable for mid-term storage of healthy onions or those onions with shallow surface diseases whose disease development could be halted. Onions containing hidden internal diseases were exasperated by the warm circulating air, causing further disease development.
