Abstract

Foliar treatments of 4-amino-3,5,6-trichloropicolinic acid (picloram) induced rapid procambium activity in western iron-weed (Vernonia baldwini Torr.) leaves. Increased meristematic activity was followed by destruction of the phloem parenchyma, sieve elements, and companion cells. Cell destruction in the vascular bundle was concomitant with that in the mesophyll.
