Abstract
The fatty acids of the major glycerolipids from the leaves of V. faba and H. vulgare plants treated with 3 different concentrations of pyridazinone derivatives were analyzed. These compounds showed multiple effects on the levels of lipids and pigments. At low concentrations, the primary effect of San 9785 was on the level of linolenic acid (18:3) in the galactolipids of V. faba, whereas the effect of San 6706 was primarily on the trans-.DELTA.3-hexadecenoic acid (16:1) content in phosphatidylglycerol. At higher concentrations, the 2 compounds reduced the content of both fatty acids in the leaves. The results appear to indicate a differential effect of these herbicides on fatty acid accumulation and a difference in susceptibility of 2 fatty acids in the species examined. EM studies revealed that 2 herbicides caused different abnormalities in V. faba chloroplast ultrastructure.This publication has 9 references indexed in Scilit:
