Abstract

Water deficit is one of the most important factors affecting plant physiology and development. Drought induced by PEG6000 inhibited main root and stimulated lateral root development. 2mg/l IAA supplemented in MS½ media causes early flowering by suppressing main root elongation and stimulating lateral root development. The increasing of IAA and decreasing of ABA in root are necessary in Amaranthus viridis flowering. Roles of plant growth regulators on the relationship between root development and flowering were discussed.
