Abstract Temporary Immersion Bioreactor (TIB) is an efficient tool for plant mass propagation
because it increases multiplication rate and plant quality. Little knowledge is available on
the ecosystem and physiological behavior of plantlets in this new technique of culture. In
order to evaluate the effects of these conditions on physiological change of plantlets, the
composition of headspace (CO2, O2 and ethylene) was analyzed at different moment during
the whole in vitro period and during 3 hours after the immersion of plants. The evolution of …
