Abstract
Isolated protoplasts (Vicia faba) suspended in a mannitol solution over a time period of about 10 d undergo a process of aging characterised by increased ethane formation, decrease in oxygen evolution and CO2 uptake, pigment degradation and a change in certain enzyme activities (ribulose-1,5-bisphosphate carboxylase and protease). The technique of immobilisation of protoplasts in a cross-linked alginate matrix offers a way to delay the appearance of the indicators mentioned. Various possible mechanisms for the increased stability of protoplasts are discussed.
