摘要:

为厘清伊犁河谷早熟苹果果实中不同矿质元素的内在关联,明确这些矿质元素与主要果实品质指标的相互作用,筛选出调控果实品质的关键矿质元素,以期为苹果示范园平衡施肥及提质增效提供理论支撑。以该区域8个早熟苹果品种的果实为试验材料,通过典型相关分析与通径分析,系统分析果实矿质元素与主要品质指标间的相关性及通径系数。典型相关分析表明,可滴定酸含量与Zn含量、固酸比与K含量均呈现显著正相关;单果质量、可滴定酸含量与K含量、可溶性糖含量与Ca含量、固酸比与Fe含量呈显著负相关。通径分析得出,对单果质量的直接影响强度依次为Zn>Ca>Fe>K>Mg;对果实硬度的直接影响强度排序为Zn>K>Mg>Ca>Fe;对可溶性固形物的直接影响强度依次为Mg>Zn>Fe>K>Ca;对可滴定酸的直接影响强度排序为Fe>Zn>K>Mg>Ca;对可溶性糖的直接影响强度依次为Ca>K>Fe>Zn>Mg;对固酸比的直接影响强度依次为Mg>Ca>Fe>Zn>K。

Abstract:

The purpose of this study is to clarify the internal relationship between different mineral elements in early-maturing apple fruits in Ili River Valley, to clear the interaction between these mineral elements and main fruit quality indicators, and to screen out the key mineral elements that regulate fruit quality, providing theoretical support for the formulation of reasonable nutrient fertilization scheme and high-quality and efficient production of apples. In this study, the fruits of 8 early-maturing apple varieties in this area were used as experimental materials, and canonical correlation analysis and path analysis methods were applied to systematically study the correlation and path coefficient between fruit mineral elements and main quality indicators. The results of canonical correlation analysis showed that there were significant positive correlation between titratable acid content and Zn content, solid-acid ratio and K content; the single fruit weight, titratable acid content and K content, soluble sugar content and Ca content, soluble sugar content and Fe content showed significant negative correlation. Path analysis showed that the direct effects on single fruit weight were Zn>Ca>Fe>K>Mg; the order of direct influence on fruit hardness was Zn>K>Ca>Mg>Fe; the strength of direct effect on soluble solids was Mg>Zn>Fe>K>Ca; the order of direct effect on titratable acid was Fe>Zn>K>Mg>Ca; the order of direct effect on soluble sugar was Ca>K>Fe>Zn>Mg; the strength of the direct effect on the solid-acid ratio was Mg>Ca>Fe>Zn>K.
