Field plots of garland chrysanthemum (Chrysanthemum coronarium L.). Kale (Brassica oleracea L.) and spinach ( Spinacia oleracea L.) were exposed to three 0.3mm simulated fog episodes per week at specific acidities from pH 1.6, 2.6, 3.6, 4.6 and 5.6 treatments. For all three vegetables, foliar injury was assessed to determine damage response levels, The most severe injury occurred near pH 1.6, and no injury was observed above appoximately pH 3.6, Decrease of leaf area of kale was also most severe at pH 1.6 but was appoximately 20% less severe than those of spinach and garland chrysanthemum at this acidity. |
