摘要：
Esterase isoenzyme spectra of different organs of seedlings and field-grown plants of fiber flax (Linum usitatissimum E., cv. Belinka) were studied by electrophoresis in polyacrylamide gel for estimating ontogenetic variability of gene expression. Formation of individual isoesterases depended on the type of tissue and the stage of its development. Isoesterases characteristic of exclusively one or some tissues of the same developmental stage were revealed simultaneously with basic esterase isoforms active in all analysed parts of seeds, seedlings and field-grown plants, The revealed changes of esterase isoenzyme spectrum during germination show tissue and time specificity of the endogenous regulation of genes controlling their formation.
