新疆中亚生态群杏品种果实与叶片形态特征相关性

【目的】研究新疆中亚生态群杏品种果实和叶片的形态特性及相关性,为新品种选育提供理论依据。【方法】以隶属于该生态群的80个新疆杏品种为研究对象,测定其在果实成熟期的叶面积、叶片长、叶片宽、叶周长、单果重、果实纵横侧径,分析这些指标的分布特性和彼此间的相关性。【结果】80个新疆中亚生态群杏品种中,77.5%的杏品种叶面积分布在19.8~30.3 cm²,最大叶面积为44.18 cm²,最小叶面积为12.82 cm²,叶面积整体偏小;86.3%杏品种叶周长分布在16.7~22.7 cm,最大叶周长为24.44 cm,最小叶周长为13.66 cm;63.8%杏品种单果重分布在16.1~32.1 g FW,最大单果重为48.07 g FW,最小单果重为12.13 g FW,果实整体偏小。叶面积与叶片宽之间相关性最高(0.910^**),叶周长与叶片长之间相关性最高(0.870^**),单果重与果实横径之间相关性最高(0.913^**)。【结论】叶面积和叶周长与果实的单果重之间极显著正相关,可作为预测果实单果重的重要指标。

Correlation Analysis between Shape Characteristic Parameters of Apricot Fruit and Leaf from Central Asia Sinusia in Xinjiang

【Objective】 The aim of this project is to reveal the shape characteristic parameters of apricot fruit and leaf from Central Asia sinusia in Xinjiang, and correlation between them in the hope of providing theoretical basis for the study of the apricot population characteristics and new cultivars breeding. 【Method】 80 apricot varieties belonging to Central Asia sinusia were selected as the experimental materials. Their fruit fresh weight, fruit vertical and transect diameter, leaf area, leaf length, leaf width, leaf perimeter were measured at fructescence. Meanwhile, the distribution regularities and correlation coefficients of those indexes' parameters of apricot in Central Asia sinusia were analyzed. 【Result】 The results showed that among 80 apricot varieties in the ecological group of Central Asia in Xinjiang, the largest leaf area was 44.18 cm², the smallest was 12.82 cm², 77.5% apricot varieties leaf area in Central Asia sinusia were distributed in 19.8-30.3 cm², and the leaf area as a whole was relatively small. The leaf perimeter of the 86.3% apricot variety was distributed between 16.7 and 22.7 cm, the largest leaf perimeter was 24.44 cm and the smallest was 13.66 cm.;The largest fruit weight was 48.07 g FW, the smallest was 12.13 g FW, the fruit weight of 63.8% apricot varieties were distribute in 16.1-32.1 g FW, and the fruit as a whole was relatively small. The correlation between leaf area and leaf width was the highest (0.910^**), the correlation between leaf circumference and leaf length was the highest (0.870^**), and the correlation between single fruit weight and fruit transverse diameter was the highest (0.913^**).【Conclusion】 There was a significant positive correlation between leaf area and leaf circumference and single fruit weight, which can be used as an important index for predicting the fruit single-fruit weight.
