Foliar Fatty Acids and Sterols of Soybean Field Fumigated with SO2

摘要: Sixty-day-old soybean plants were exposed in the field to 78.7 parts per one-hundred million of SO(2) an open-air fumigation system for 20 days. Leaves from top one-fourth and bottom analyzed chlorophyll, free fatty acids, acid esters, polar lipid sterols. Fumigated had a lower acid, content, but higher ester content. Of individual linoleic linolenic increased with while palmitic decreased. fumigations only minor effect on leaf In general, lower, more mature leaves showed greater response exposure.
