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.
应用硅油离心技术于从绿化的白化燕麦叶片中分离出的原质体和原叶绿素体，表明质体包膜对赤霉素、脱落酸和腺苷 3'，5' -环磷酸酯相对不透。然而，在绿化的早期阶段，所有物质的渗透性都有明显增加，特别是在 2 小时后。此后所有通量都减少，但仍保持高水平的脱落酸。
