| Abstract: | After the removal of xylem in Broussonetia papyrifera (L.) Vent.treelets,an IAA\|transport inhibitor TIBA (tri\|iodobenzoic acid) was applied around the trunk above the portion removal of xylem.TIBA inhibited the promotion of IAA on the regeneration and activity of cambium and phelogen,and differentiation of xylem and phloem.And the changes of peroxidase and esterase isozyme during the regeneration were closely related with the differentiation of the regenerated tissues. |

| Keywords: | TIBA (tri\|iodobenzoic acid) peroxidase isozyme esterase isozyme Broussonetia papyrifera regeneration after removal of xylem |
