Translocation and Distribution of Picloram in Bean Plants Associated with Nastic Movements

AUTOR(ES)
RESUMO

Nastic responses in bean plants (Phaseolus vulgaris L. var. Black Valentine) occur rapidly when very low concentrations of picloram (4-amino-3,5,6-trichloropicolinic acid) are applied to the root systems. The distribution of picloram associated with nastic responses was quantitatively determined in root-treated plants.
