Induction of flowering by cytokinins in a short-day plant, Lemna paucicostata

Abstract

Lemna paucicostata, normally a short-day plant, can be induced to flower under long-day conditions by providing a cytokinin in a medium containing a high level of ferric citrate (5 × 10-4M). Interestingly, when a cytokinin and EDDHA are present together in the medium, flowering is induced even at low levels of iron (10-5 and 5 × 10-5M ferric citrate). However, in the absence of a cytokinin, flowering takes place only under short days
