‘灰枣’果实外观品质指标相关性分析

Correlation Analysis on Morphological Traits of Ziziphus jujuba‘Huizao’Fruit

    摘要
  • 摘要: 以新疆主栽品种‘灰枣’Ziziphusjujuba‘Huizao’作为供试材料，研究其果实纵径和横径、果核纵径和横径、单果质量、果肉质量、果核质量和可食率等品质指标及其相关性，分析果实纵径、横径与果核纵径、横径之间的线性回归特征参数。结果表明，‘灰枣’果实外观品质指标均有不同程度的变异范围，其中果核质量、果肉质量和单果质量的变异系数均较大（大于20.00%），核形指数和果核纵径、横径的变异系数均在10.00%~20.00%，其余指标的变异系数均小于10.00%，其中果实可食率的变异系数最小（2.96%）。相关性分析结果表明，‘灰枣’果实外观品质指标中，大部分指标间均存在显著相关性，其中果实纵径、横径与果核纵径、横径之间均存在极显著正相关关系（P<0.01），相关性系数（R）分别为0.47、0.49，单果质量与果肉质量和可食率之间也均存在极显著的正相关关系（P<0.01），R分别为0.99、0.58，但果核质量与单果质量和果肉质量之间的相关性均未达到显著水平（P>0.05）。线性回归分析结果表明，果实纵径（y）与果核纵径（x）之间的直线回归方程为y=0.61x+21.34，R2=0.22，回归方程系数（斜度）为0.61，果实横径（??′）与果核横径（??′）之间的直线回归方程为??′=0.96??′+17.14，R2=0.24，回归方程系数（斜度）为0.96，随着果实纵径的增大，果核纵径的增加程度相对较小，而果实横径和果核横径的变化比例基本相同。综上，依据‘灰枣’果核纵径、横径的大小，在一定程度上能够更准确地测算果皮表面已皱褶的果实纵径、横径，从而科学地测量‘灰枣’果实饱满度。

     

    Abstract: On November 2021, fruits of Ziziphus jujuba‘Huizao’ cultivated were collected in orchards at 8 villages of Wenfu county, Xinjiang. Determinations were conducted on vertical and horizontal diameter of fruit and stone, single fruit weight, pulp and stone weight, edible rate. The results showed that the morphological traits of dates had different variation, especially weight of pulp and stone, single fruit had more than 20.00% of coefficient of variation, stone morphological index, stone vertical and horizontal diameter between had10.00%-20.00% , and the other traits had less than 10.00%, with the smallest of fruit edible rate (2.96%). Correlation analysis showed that there was significant correlation among the most of the fruit morphological traits. There was extremely significant positive correlation between vertical and horizontal diameter of fruit, vertical and horizontal diameter of stone, with correlation coefficient of 0.47 and 0.49, as well as between single fruit mass with pulp weight and edible rate (P <
