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.
对蚕豆亚种大粒型垂挂品种胚乳中进行无丝分裂的细胞核,在福尔根反应后进行了细胞光度测量。DNA含量的测量表明,倍性水平较低的细胞核会均等分裂。倍性水平较高的细胞核分裂会产生DNA含量相等和不等的细胞核。倍性水平较高的细胞核仍可进行有丝分裂,这导致胚乳细胞核中DNA含量趋于均等。
