报告摘要：
Fresh fruits are living organs that are continuously breathing and transpiring. Manipulation of breath and water loss (gas exchange of O2, CO2, H2O) is an essential part of postharvest research and operations. In general, postharvest operations such as low temperature storage, controlled atmosphere (CA) storage, modified atmosphere packaging (MAP) are targeted to reduce respiration rate and water loss to keep fruits fresh. However, fruit disorders may develop as consequences of over manipulation. Ethylene, a gas that regulates fruit growth, maturation and ripening also play an important role in maintaining fruit quality. Managing ethylene production, exchange and functioning is also an important part of postharvest practice. Gas treatments such as fumigation affect storage quality through inhibition of microbial growth and insect damage. This presentation will showcase the theories and practices to extend storage and shelf life through manipulation of gas exchange.
