DNA synthesis in the nuclei of Pinus silvestris embryos during

P. Brodzki

Abstract


DNA synthesis starts earliest in the apical meristem of the shoot, and latest in the cotyledons. Mitoses appear simultaneously in the apical meristem and in the hypocotyl cortex. Synthesis continues in the mother cells of vascular elements and cotyledon parenchyma when mitosis ceases. In the cotyledons DNA synthesis is rather synchronous and leads to the elimination of 2 C nuclei.
