Abstract:
The impact of nitrogen source on the response of cucumber (Cucumis sativus) seedlings to sub-toxic concentrations (<10-6m) of metolachlor and EPTC was studied in nutrient solutions. Nitrogen increased the phytotoxicity of low concentrations of both herbicides. The presence of a relatively high ammonium level (5mm) in solution enhanced growth inhibition (up to 50%), increased total nitrogen (20%) and protein content (26%), and resulted in less K+ (50%) and Ca2+ (70%) absorption. Under optimal nitrogen nutrition conditions, metolachlor temporarily inhibited plant growth, and both herbicides decreased the protein content in cucumber leaves. The effect of herbicides at the high ammonium level on plant growth was stronger and more long-lasting compared with control growing conditions. © 1992.
