Oxygen Consumption by Phalaenopsis Plantlets and Chrysanthemum Cuttings as a Function of Temperature and Time: Model Structure Validation

Phalaenopsis spp. and Chrysanthemum are ornamentals with an important economic value. Currently, quality loss during storage transport of plantlets cuttings is a limiting factor for spreading the workload, broadening export range, use slower but more environmentally friendly transport. In agro-food sector, equilibrium modified atmosphere packaging has enhanced shelf-life minimally processed produce. The required properties system can be estimated from respiration rate packaged commodity under specified atmospheric composition temperature. this work, model structure validated to estimate as function oxygen concentration temperature Chrysanthemum. time was monitored in closed different temperatures. models show good fit data. coefficients were dependent on plant species characteristics. resulting formulae used consumption produce range concentrations 15 °C 32 2 14 which valid depend species. dynamic profile
