摘要
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。
The resistance of 128 peony varieties to air fluoride pollution has been determined according to the disease index of peony leaf tip blight in the region of air fluoride pollution.The results indicate that the resistance of differential varieties to air fluoride pollution is very different,the resistance index of the investigated varieties ranges from 20 to 80.The results of further study show that the difference of the varietise resistance is due to the difference of their tollerance to fluoride in the leaf,there is clearly no difference of absorbing fluoride among the peony varieties of different resistance.
