應用

(+)-Abscisic acid has been used:
  • as a supplement for the germination of Arabidopsis thaliana seeds
  • as a component of buffered nodulation medium to check its effects on lateral root density (LRD) in leguminous and non-leguminous plants
  • as a standard to study its effects on root meristem defects in Medicago truncatula latd mutant
