Abstract
We applied 5 and 2 parts/106 of simazine, atrazine, igraii, GS-14254, propazine, prometryne, prometone, or ametryne to the foliage of 3-week-old seedlings of peas (Pisum sativum L., cv. Perfected Freezer) and sweet corn (Zea mays L.f cv. Iochief) growing under greenhouse conditions on perlite and supplied with complete Hoagland's solution. The results indicated a higher content of protein in the treated leaves than in the leaves of untreated controls. (7 to 35 per cent for pea seedlings and 0 to 50 per cent for corn seedlings.) Treated leaves had significantly less starch and sugars than the controls. The activities of nitrate reductase (NRase) and glutamic-pyruvic transaminase (transaminase) were enhanced, but there was no significant effect on ribonuclease (RNase).Keywords
