Abstrakt: | Abstract: 3 peaks of DNA synthesis were observed in the barley embryo of seeds, germinating for 49 h in running tap water at 25°C. The first peak, found after 22h, was formed by S-cells in the roots and in the 1st leaf meristem. The second peak (after 34-37h) and third peak (after 46-49 h) represents the S-cells in the roots, apex and 1st, 2nd and 3rd leaf meristems. Application of N-methyl-N-nitrosourea for 3 h at the onset of germination inhibited the rate of DNA synthesis and postponed the peaks of DNA synthesis in individual meristems of the embryo. |
