| Abstract: | Changes in the pattern of distribution of acid-phosphatase activitywere followed during the period of regeneration and wound-vesselformation in Coleus internodes. The activity of this enzymewas associated with three phases of wound regeneration, thefirst of which was detected only in the damaged surface cellsduring the first few days after wounding. The second phase wasassociated with the undamaged cells immediately surroundingthe wound and this travelled gradually inwards from the woundsurface to the deeper tissues as a wave of activity during regeneration.This activity preceded cell division in the zone around thewound and was not detectable once the new cell walls had formed.The third phase was associated with the differentiation of cellsof the new vascular tissues which formed around the wound connectingthe original severed vascular bundle. |
