Phytotoxicity of Profluralin to Rottboellia exaltata L.

Author: Marita Ignacio-Galinato


The effect of a pre-emergence herbicide on the growth of Rottboellia exaltata L.F. was determined using different concentrations of profluralin or CGA-10832.

Abnormal enlargement of the cells was apparent in all swollen tissues. Multi-nuclearity of the cells in the pericyclic layer and increase in the number of root and leaf primordium initials were likewise observed.
