The aminoacylation of tRNA and activity of ribosomes from hybrid and inbred maize seedlings in the cell-free system of protein synthesis from wheat germs and ribosome sedimentation profiles in the sucrose density gradient have been investigated. A positivecorrelation between the level of heterosis manifestation and the quantity of polysomes in the total ribosomal-preparation, the functional-activity of polysomes and aminoacylation of tRNA in vitro is established in the hybrid generation of plants.
