Abstract:Uridine and thymidine incorporation into the peripheral vs.central zone of the Japanese Morning Glory apex, as well asinto the apical leaves, was measured a few hours before andbeyond the end point of the inducing long night. The enhancedincorporation was greatest in the peripheral zone and in theapical leaves suggesting that immediate pre-prefloral effectsare mainly expressed "vegetatively".
