Abscisic acid as a stimulator for rice mesocotyl growth

, : Abscisic acid as a stimulator for rice mesocotyl growth. Nature New Biology 238(81): 92-93

With rice plants grown in darkness on culture medium containing ABA and/or GA, mesocotyl elongation was markedly increased by ABA at 2 ppm when compared with the water control. In the presence of GA, ABA showed a synergistic reaction. The seedlings could be separated into those with tall shoot and short mesocotyls and those with short shoot and long mesocotyl. The results indicated that an endogenous ABA is involved in growth of rice mesocotyls.
