Shasta chrysanthemum (Chrysanthemum morifolium Ramat) showed less SO/sub 2/ induced leaf necrosis than Hurricane. The growth retardant a-cyclopropyl-a-(4-methoxy-phenyl)-5-pyrimidine methanol (ancymidol) at 0.16 and 0.48 mg ai/2.5 cm pot reduced SO/sub 2/ damage on both cultivars. There was positive correlation between stomatal activity (water diffusion resistance) and degree of leaf necrosis from SO/sub 2/.
