Respiratory pathways in aged soybean seeds

摘要: Respiratory activities in soybean seeds (Glvcine max (L.) Merr. cv. Chippewa 64) have been examined the first minutes after water imbibition and three hours of imbibition, using either particles or intact axes. Cyanide azide were utilized as inhibitors cytochrome oxidase pathway respiration, SHAM inhibitions interpreted effects on alternative pathway, since unaged axes by obtained only when respiratory activity had restricted with expanded an uncoupler (CCCP). From experiments these inhibitors, it is suggested that utilize both respiration pathways cotyledon but axis. Accelerated aging causes a marked deterioration especially through there associated engagement seed It lowering shift may play major role decline germinability vigor.
