摘 要：
以薄皮木当年种子为试材,研究了相对含水量、基质、盐胁迫和pH值等因素对其种子萌发的影响,以期为薄皮木引种驯化和开发利用提供理论依据。结果表明:基质含水量为26.67%时,发芽率和发芽势最高,分别达到30%和20%;薄皮木种子具有广泛的土壤适应性,以沙子、蛭石混合物(比例1∶1)作萌发基质最为适宜;当NaCl浓度为0.5mol/L时,种子萌发率最高为43.43%;在pH 3.0～11.0范围内均可萌发。

摘 要：
Taking the new seeds of Leptodernis oblonga Bge.as experiment materials,the relative water content,ground substance,salt stress,pH,which had effect on the seeds were studied.The purpose of the research was to supply theoretical foundation for introduction,domestication and cultivation of Leptodermis oblonga Bge..The results showed that when relative water content was 26.67%,the seed germination rate and germination potential were made up to 30.00% and 20.00%.The seeds had wide adaptability to soil,optimum of sand and vermiculite mixture(1∶1).When the concentration of NaCl was 0.5 mol/L,the germination rate was highest reach to 43.43%.The seed had wide adaptability to solution pH from 3.0 to 11.0.
