N2 - One selected variety from eight species of ornamental plants was used to determine the range of phytotoxic responses to hydrogen chloride gas. Plants of several ages were exposed to varied concentrations of the gas for periods of 20 min each. Injury on exposed plants was evaluated 24 h after completion of exposure and injury symptoms were numerically rated and described. The selected species of plants included aster (Callistephus chinensis), calendula (Calendula officinalis), cornflower (Centaurea cyanus), cosmos (Cosmos, sp.), marigold, American (Tagetes erecta), marigold, French (Tagetes patula), nasturtium (Tropaeolum, sp.), and zinnia (Zinnia angustifolia). Of these, cosmos and both marigolds appeared to be the most sensitive to HC1. Plant injury estimated at the 10% level was caused by 20 min exposure to 6.5 and 8.7 mg HCl m-3* * mg HCl m-3 = ppm × 1.5..
