Glyphosate brought the biggest vice-effects, clethodim took the second and fenoxaprop-p-ethyake minimum:(1)As to the pure growth, MDA accumulation, the relative permeability of plasma membrane and chlorophyll content, glyphosate had evident influences on them in the daily dosage, 1/2 and 1/4 of the daily dosage . The walnut seedling dried and died twenty days later.(2)The influences of clethodim in different concentration such as double daily dosage, daily dosage and 1/2 of daily dosage on the above four indexes demonstrated differently, the more concentration was, the more severe the influence. was. With the concentration reducing, the influence weakened gradually.(3) Double daily dosage, daily dosage and 1/2 daily dosage of fenoxaprop-p-ethy exerted a slight vice-influence to the MDA accumulation, the relative permeability of plasma membrane and chlorophyll content.
