title: [Complementary nuclear DNA in embryo sac cells of Haemanthus albiflos and Ornithogalum caudatum].
abstract: Cytophotometric measurements of Feulgen-DNA were carried out in the nuclei of embryo sac cells of Haemanthus albiflos and Ornithogalum caudatum. It was found that the nuclei of the egg system, haploid in the number of chromosomes, became polyploid in DNA amount at the final stages of gametophyte development.
