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。
The leaf area, leaf length, leaf width and leaf index of apricot cultivars in different ecotypes in the same habitat were determined with the Central Asian Minority Ecology Group, the Zhungeer-Ili Ecology Group and the North China Ecology Group as the test materials. Leaf area distribution rules, the establishment of a mathematical model of leaf area estimation. The results showed that the leaf area of the apricot cultivars in the three ecotypes showed a right (left) skewed distribution with the largest mean leaf area in the North China ecotone and the smallest in the Central Asia. The leaf area distribution of more than 50% Within a certain value range of the ecological group, the range of values is North China Ecological Group> Central Asia Minor Ecological Group> Zhunge’er-Ili Ecological Group; the correlation between long and wide products and leaf area is the highest, and the leaf area increases with long and wide product The growth can be fitted by a quadratic curve equation; and the mathematical model of leaf area estimation of each ecological group can better estimate the leaf area of each ecological group within the range of values.
