摘要：以乌兰布和沙漠绿洲防护林体系新疆杨、毛白杨、银中杨为研究对象,通过测定叶片饱和鲜质量、干质量及叶面积,分析了3种杨树的比叶面积、叶干物质含量的差异,探讨了3种杨树的适应性。结果表明:叶面积、叶宽、叶周长、叶形指数为毛白杨>银中杨>新疆杨,叶长、叶长宽比为银中杨>毛白杨>新疆杨。3种杨树之间的比叶面积(SLA)与叶干物质含量(LDMC)均存在显著差异(P <0.05)。银中杨、毛白杨、新疆杨比叶面积分别为(21.232±2.105)、(19.080±1.826)和(13.347±0.824) m^2·kg^-1,叶干物质含量分别为(249.007±14.743)、(273.814±23.336)和(299.431±6.011) mg·g^-1。比叶面积与叶干物质含量存在显著负相关关系(P <0.05),两者呈幂函数关系(y=ax^-b)。干质量与叶面积存在显著正相关关系(P <0.05),两者呈幂函数关系(y=ax^b)。干质量与比叶面积存在显著负相关关系(P <0.05),两者呈线性函数关系(y=-ax+b)。新疆杨适应性优于毛白杨、银中杨,建议今后该区防护林体系的更新可优先选择新疆杨。
Three poplar species(Populus alba var. pyramidalis Bge., Populus tomentosa and Populus alba × Populus × berolinensis)of oasis protection forest system in Ulan Buh Desert were selected as the research object. The environment adaptation of the three poplar species was discussed with specific leaf area and leaf dry matter content which were analyzed through the measurement of leaf saturated fresh weight, leaf dry weight and leaf area. The result showed that leaf area, leaf width, leaf perimeter, leaf factor was Populus tomentosa> Populus alba × Populus × berolinensis > Populus alba var. pyramidalis Bge., leaf length, leaf length and width ratio was Populus tomentosa > Populus alba × Populus × berolinensis > Populus alba var. pyramidalis Bge.. There were significant differences in specific leaf area and leaf dry matter content(P < 0.05) among the three species. Specific leaf area and leaf dry matter content of Populus alba × Populus × berolinensis, Populus tomentosa and Populus alba var. pyramidalis Bge. were(21.232±2.105) m^2·kg^-1 and(249.007±14.743) mg·g^-1,(19.080±1.826) m^2·kg^-1 and(273.814±23.336)mg·g^-1,(13.347±0.824) m^2·kg^-1 and(299.431±6.011)mg·g^-1, respectively. The specific leaf area was significantly and negatively related to the leaf dry matter content(P < 0.05), its a power function relationship(y=ax^-b). The dry leaf weight was significantly and positively related to the leaf area(P < 0.05), its a power function relationship(y=axb). The dry leaf weight was significantly and negatively related to the specific leaf area(P < 0.05), its a linear function relationship(y=-ax+b). The adaptability of Populus alba var. pyramidalis Bge.was higher than Populus tomentosa and Populus alba × Populus × berolinensis, Populus alba var. pyramidalis Bge. in the restoration of protection forest should be priority selected in Ulan Buh Desert Oasis.
