The effects of growth regulators on flowering of Chenopodium murale plants in vitro

Abstract

In vitro culture of Chenopodium murale L. (ecotype 197) green and herbicide SAN 9789 - treated "white" plants was established and the effects of benzylaminopurine (BAP), indole-3-acetic acid (IAA) and gibberellic acid (GA(3)) on growth and flowering were tested. Green plants did not flower on glucose free media, while 17 % of plants flowered on 5 % glucose-containing medium. SAN 9789 (10(-5) M) inhibited growth and flowering. BAP and IAA (0.1 - 5 mg dm(-3)) also inhibited growth and flowering of green and "white" plants. GA(3) (10 mg dm(-3)) stimulated leaf development in green plants, but had no significant effect on "white" plants, and stimulated flowering of green (41 %) and "white" (33 %) plants.
