摘要：
The effects of exposing plants of Dryopteris filix-mas (L.) Schott, Phyllitis scolopendrium (L.) Newman and Polypodium vulgare L. to 60 nl litre-1 (122 μg m-3) NO2 for 37 weeks were investigated in a closed chamber fumigation system. There was no effect of NO2 on the numbers of fronds produced for any species at any time during the exposure period. However, at the end of the study, there was a lower dry weight yield of green shoots of D. filix-mas and P. scolopendrium and a higher yield of green shoots of P. vulgare for plants in the NO2 treatment as compared to control plants. These differences in shoot dry weights were not accompanied by an effect of NO2 exposure on total plant dry weights. © 1990.
