The growth of isolated barley embryos cultivated under different conditions

Isolated barley embryos were cultivated aseptically in three different complete media. The growth of the primary root of each embryo was measured during four days of cultivation. Embryos were cultivated on three different consistencies of media: on agar plates, on cellulose tissue moistened with the medium and in liquid shaken cultures. The last way of cultivation yielded the highest degree of the growth of roots. Optimum combination of conditions in shaken liquid medium was selected on the basis of systematic study. The growth of roots of isolated embryos under appropriate conditions approaches that of roots of seedlings cultived on moistened blotting paper.
