• In vitro cultured shoots of three Chinese poplar species (Populus tomentosa, P. alba cv. Pyramidalis and P. euphratica) and an improved poplar (FS-51), as a control, were exposed to the stress of low osmotic potential, salinity and high pH, and the shoot growth was measured. P. tomentosa and P. euphratica could grow even under the high osmotic stress (0.5 M mannitol; -1.7 MPa). P. euphratica shoots which were previously cultured on the medium containing 0.7 M mannitol (-2.4 MPa) recovered its growth after being transplanted to the medium without mannitol. The shoot growth of P. euphratica was not so reduced even on the medium containing 100 mM NaCl. However, growth of the other poplars markedly reduced with 10 mM NaCl. Medium pH (pH 5.8-10) also did not affect the shoot growth of P. euphratica. These poplars have different tolerance to the stresses in cultured shoot in vitro. P. euphratica was extremely tolerant to the stresses which are possible to damage plants in dry land.
