- 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。
- Abstract:
- Taking leaves of CentroAsiatic，SongaricaYili,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 3 ecological groups were analyzed.The results showed that its leaf area revealed the law of right,left skewed distribution in 3 ecological groups.Mean values of leaf area in North China ecological group was the largest,and CentroAsiatic ecological group was the smallest.About 50% varieties leaf area in 3 ecological groups distributes in a round value range,and the value range of in North China ecological group>CentroAsiatic 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 3 ecological groups could be well estimated in their value range use their mathematical models which be constructed.
