| Abstract: | Rooted cuttings of two Picea abies-clones were fumigated with O3 and O3+ SO2 for 12 weeks. After 4 and 16 months without fumigation the treated plants showed much higher sensitivity to drought (expressed in osmotic potential of cell sap and in percent survival) than the untreated ones. |
