Cytological Study on Induced Apospory in Ferns

open access: yesCYTOLOGIA, 1962
The study was carried out in order to bring about a better understanding of the life cycle of the pteridophyte by means of experimentally induced apospory. Inducing apospory was successful in Pteridium aquilinum var. latiusculum and Dryopteris erythrosora, but the former was exclusively used in the precise study because of the rapid growth of the ...
