title: Anther culture in rice: IV. The effect of abscisic acid on plant regeneration.
abstract: The effect of abscisic acid (ABA) on plant regeneration in anther-derived calli of rice Oryza sativa L. varieties Taipei 177, Taipei 309 and Fujisaka 5 was studied.ABA at concentrations up to 4×10(-6) M stimulated fresh weight increase in Taipei 309 and Fujisaka 5 while higher concentrations effected corresponding weight decreases in the three varieties tested. Relatively high ABA concentrations resulted in decreased callus size and production of more compact and whitish calli. ABA increased the frequency of calli producing green plants in Taipei 309 and the average green plant regeneration in all varieties tested.
