Abstract:We have investigated the morphology and the cytogenetics in cultivated stem cells of pea (Piswn sativum L.) and faba bean (Vi cia faba L.) at the initial stages of callus development in liquid nutrient medium containing different concentrations 2, 4-D (2,4-dichlorophenoxyacetic acid) ofO, 2, 4, 8, 16 and 32 mgt 1 . The earliest stage of callus development in both species was indicated by the formation of specific morphological patterns -the so-called dividing rows (DR). These arose after periclinal divisions… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
