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.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
