Effect of Heavy metal stress on spore germination of Pteris confusa T. G. Walker and Pteris argyraea T. Moore [PDF]

open access: yes, 2011
Background: Plants have both constitutive and adaptive mechanisms for coping with the elevated metal concentrations and they are utilized to clean the polluted soil and water. Unlike angiosperms hyperaccumulators, fern hyperaccumulators are equipped with

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 ...
