Summary
Application of the technique of silicone oil centrifugation to etioplasts and etio-chloroplasts isolated from greening etiolated Avena sativa L. laminae has shown that etioplast envelope membranes are relatively impermeable to gibberellic acid, abscisic acid and adenosine 3′,5′-cyclic phosphate. However, there is a marked increase in permeability for all in the early stages of greening, particularly after 2 h. All fluxes are reduced thereafter but a high level of abscisic acid still remains.
