Ploidy levels were studied of asparagus plants propagated by rooted cuttings and callus tissue culture. A shift to the tetraploid condition was observed in the majority of plants derived via the callus tissue culture method and in rooted cuttings which developed callus as they rooted. Rooted cuttings without callus remained diploid. Meiotic abnormalities and low fertility were observed in the tetraploids.

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.
