Respiratory activity, ethylene emission and temperature quotient in cold stored grapefruit.

 

Grapefruits (cultivars Marsh Seedless and Redblush) were harvested in May and Nov., respectively, and stored at 7, 10, 13 or 20 deg C for 10 weeks. CO2 and ethylene production increased with temperature in a non-climacteric manner. At the beginning of storage, respiration rates in Marsh Seedless fruits ranged from 2 ml CO2 kg-1 h-1 at 7 deg to 12 ml CO2 kg-1 h-1 at 20 deg . The comparative figures for Redblush fruits were 4.4 and 15.3 ml CO2 kg-1 h-1, respectively. Ethylene production ranged from 0.02 to 0.08 micro litre kg-1 h-1 at 7 deg and 20 deg , respectively, for Marsh Seedless. The comparative rates for Redblush fruits were 0.03 to 0.15 micro litre kg-1 h-1, respectively. Marsh Seedless fruits had higher Q10 values at 10 deg and 20 deg than Redblush fruits, particularly at the beginning of storage. Q10 values decreased during storage.
