摘　　要：以中亚细亚生态群、准葛尔-伊犁生态群、华北生态群杏品种叶片为试材,测定同一生境下不同生态群杏品种的叶面积、叶片长、叶片宽、叶形指数,分析各生态群叶面积的分布规律,建立叶面积估算的数学模型。结果表明:3个生态群杏品种叶面积呈右(左)偏态规律分布,以华北生态群的叶面积平均值最大,中亚细亚生态群最小;各生态群有50%以上的品种叶面积分布在该生态群的某一取值范围内,且取值范围华北生态群>中亚细亚生态群>准葛尔-伊犁生态群;长宽积与叶面积的相关性最高,叶面积随长宽积的增长可用一元二次曲线方程拟合;各生态群叶面积估算数学模型,在取值范围内能较好的估测各生态群品种的叶面积。Taking leaves of Centro-Asiatic,Songarica-Yili,North China ecological groups as materials,leaf area,leaf length,leaf width and leaf index were measured.Then the distribution law and constructed mathematical model of apricot varieties leaf area in 3ecological groups were analyzed.The results showed that its leaf area revealed the law of right,left skewed distribution in 3ecological groups.Mean values of leaf area in North China ecological group was the largest,and Centro-Asiatic ecological group was the smallest.About 50%varieties leaf area in 3ecological groups distributes in a round value range,and the value range of in North China ecological group〉Centro-Asiatic ecological group〉SongaricaYili ecological group.Length by width was the highest correlation factor with leaf area,and its interrelation could be fitted to use quadratic equation.Leaf area of 3ecological groups could be well estimated in their value range use their mathematical models which be constructed.
