| Abstract: | With four poplar clones, namely 84-323 (Populus deltoides cv. '84-323'), 84-324 (Populus deltoides cv. '84-324'),79-35 (Populus × euramericana cv. '79-35'), and I-69 (Populus deltoides cv. 'Lux' I-69/55) as a control, researches on cold,drought and salt resistance of the clones were conducted. Electrolyte permeability under a series of low temperatures, relative water loss rate of detached leaves with time series and survival rate and growth performance in salt soil were measured. Thc results showed that 84-323, 84-324 and 79-35 were resistant to cold as same as I-69 (CK) and more resistant to drought and salinity than I-69 (CK). |
