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 %.

Keywords: gibberellic acid; glucose; stage of development; long-day plant; short-day plant
Subjects: Chenopodium murale; Chenopodium rubrum; daylength; flowering, darkness; gibberellins; growth analysis, biomass production; in vitro culture, growth and flowering; long- and short-day plants; short- and long-day plants, darkness
