Greenhouse studies were conducted to determine effects of zinc chloride compounds on foliar and root growth of Marigold (tagetes patula), Zinnia (zinnia elegans) and Vinca (catharanthus roseus). Four different experiments were conducted using zinc chloride compounds applied as a spray on 288 plug trays at rates of 0 (paint only), 3.5, 7, and 14 percent. Experiment I includes examining uptake of zinc into potting media. Experiment II examined plant growth at the various application rates and included a visual survey. Experiment III used microscopic studies to determine effects of zinc compounds on root growth. Experiment IV examined the effect of zinc compound rates on plant survival and if survival was species and treatment rate dependent.
