The clinorotation effect on the plastide substructure characteristics of greening barley seedlings of the variety «Zorianyi» is investigated. A comparison analysis of dynamic changes in clinorotated greening seedlings and in control ones showed the following: the volume of plastides decreased, the developing of prolamellar body and shorting of lamellae length under greening during 1 h and 3 h take place. Chloroplasts were formed only in the cells of the control variant on greening for 6 h. Possible mechanisms of the delay of transformation from etyoplasts and etyochloroplasts to chloroplasts are discussed.
