Abstract

Chenopodium rubrum, a short-day plant, and C. murale, a long-day plant, were grown in vitro in continuous darkness. Control C. rubrum plants exposed to continuous darkness for 15 d at cotyledonary phase, did not flower, while 80 % of plants flowered on the medium with 5 % glucose and 10 mg dm−3 GA3. Control C. murale plants exposed to continuous darkness for 10 d at the age of 4th pair of leaves, did not flower, while GA3 (1 – 5 mg dm−3) stimulated flowering up to 65 %.
