以污染区牡丹叶尖枯病的病情指数为依据，测定了１２８个牡丹品种对大气氟污染的抗性。结果表明，不同牡丹品种对大气氟污染的抗性不同，抗性指数的变化范围为２０～１００．抗性差异是由于叶片对氟化物的耐受性不同，而不是吸氟量多少的差异。
Based on the disease index of peony leaf blight in contaminated area, the resistance of 128 peony cultivars to atmospheric fluorine pollution was measured. The results showed that different varieties of peony had different resistance to atmospheric fluorine pollution, and the range of resistance index varied from 20 to 100. The difference in resistance is due to the different resistance of the leaf to fluoride, rather than the difference in the amount of fluoride absorbed.
