THE REACTION AND RELATIVE RESISTANCE OF PLANTS TO CHLORINE
98种园林植物对氯气的反应和抗性的研究

The experiments were carried out in a dynamic perspex fumigating cabinet. 98 species (including 46 trees, 35 shrubs, 13 herbs and 4 vines) were examined by sun light lamps with eight levels of concentration of chlorine (i.e. 0.2, 0.3, 0.5, 1, 2, 4,7,8ppm). Each fumigation lasted 4 hours.Acute injury to the leaves of the dicotyledons caused by chlorine usually occurs first on the abaxial surface of the leaves as needle-shaped stipples or both large and small concave spots. The injury to herbs with isobilater...
