摘要
本文报道用开顶式熏气装置筛选大气氟监测植物,研究监测植物在氟污染情况下的反应,以确立监测指标和监测定量化。结果表明,梅、唐菖蒲、赤胫散、火炭母、水杉、金荞麦、雪松、苹果等植物是良好的氟监测植物,其中赤胫散、火炭母是国内筛选出来的监测植物,可用来监测大气氟污染。受害浓度(阈值)、症状出现时间、受害叶面积％和叶片含氟量可作为植物的监测指标,生理反应指标作为参考。
In this paper the new monitor plants for fluoride were screened by means of open top field chamber. Some responses of monitor plants to fluoride exposure were investigated and the establishment and quantification on plant monitor index were discussed. The results showed that Prunus mume, Gladiolus gandavensis, Polygonum runcinatum, Polygonum chinense, Metasequoia glyptostroboides, Fagopyeum cymosum, Cedrus deodara and Malus pumila were fine monitoring plants for fluoride. From which the P. runcinatum, P. chinense and P. mume were newly domestically screened to monitor fluoride in atmosphere. The study on fluorde monitor index illustrated that the damage concentration threshold value, symptom appearance time, damaged leaf area (in % ) and leaf fluoride content were four indexes of plant monitor for monitoring fluoride in atmosphere with the physiological index being used for reference.
