Abstract:

研究新疆天山野果林建群种新疆野苹果(Malussieversii)光合生理特性,对于该种群保育及其生态功能评价具有重要意义。通过野外测定新疆新源天然野果林中不同径级64株新疆野苹果南向枝条上部叶和下部叶饱和光强下的净光合速率(A)、气孔导度(gs)和比叶面积(SLA)。结果表明随着径级增加,上部叶和下部叶的Aarea、Amass显著增加。gs随径级的增加先增加再降低,在径级Ⅲ(树干0.5m高处直径25~35cm)时达最大。上部叶比下部叶有着高的Aarea、Amass和gs。回归分析表明随着树干直径增加,Aarea和gs呈二次多项式增加,Amass呈线性增加。SLA随径级增加变化不显著,上部叶SLA显著低于下部叶。上部叶的Aarea高于下部叶,但由于SLA显著减小,在Amass上两者差异减小。随gs增加,上部叶Aarea呈幂函数增加,下部叶Aarea呈二次多项式增加。
