Steady State Thermal Conditions Inside Plant Tissue Culture Vessels Submitted to a Constant Level of Irradiation

Type: article
Abstract: A simple mathematical model for quasi-stationary heat and mass transfers inside plant tissue culture vessels was developed and applied to various physical conditions. The validation of the convective coefficients was done with the help of actual temperature measurements performed in situ under strictly dry conditions. The extension to water vapor mass transfers inside the vessels was then obtained by a similarity argument. When applied to describe stationary conditions, the model shows that there is ample room for modifications and improvements of the internal micro-climate of the vessels, in particular by increasing the artificial light level, without creating any noticeable thermal stress to the plants. Natural light should however be used with care, owing to its high intensity and the subsequent greenhouse effect in these particularly small size enclosures.
