Cytophotometric contribution to the knowledge of ceratonia siliqua seed develop...

Cytophotometric analysis of nuclear DNA content in differen áreas of young Ceratonia siliqua seeds were made. The relative DNA amount in 50 interphase nuclei per each area were determined using a Vickers M 85 cytodensitometer. The frequency distribuition of DNA content in individual nuclei falls in the 2C and 4C classes, with the predominance of 2C nuclei. The DNA content of normal endosperm nuclei range from 2...
