ABSTRACT
Yellow cedar seeds are dormant at maturity. The abscisic acid (ABA) content of the embryo (but not the megagametophyte) decreased approximately 2-fold following exposure of seeds to a dormancy-breaking treatment; this process was also accompanied by a 10-fold lowered sensitivity of the embryo to S-(+)-ABA. A decline in ABA within the seed is not sufficient for dormancy breakage; reduced embryo sensitivity to ABA is also required.
