Cytophotometric analysis of amitosis in nuclear endosperm of Vicia faba.
DNA content in amitotically dividing nuclei of endosperm of Vicia faba subsp. major cv. Hangdown was cytophotometrically measured after Feulgen reaction. Measurements of DNA content indicate that nuclei with lower ploidy level divide into equal parts. Divisions of nuclei with higher ploidy level result both in nuclei with equal and nuclei with different DNA content. Nuclei with higher ploidy level can still divide mitotically that lead to the equalising of DNA content in endosperm nuclei.
