不同产地长富2号苹果品质差异及其与地理坐标的相关性
Quality differences of ＂Nagafu 2＂ apple from different habitats and its correlation with geographical coordinates
摘要
Abstract
The basic quality indexes of ＂Nagafu 2＂ apple from eight different habitats of China were determined and quality comparison among these apples was made. Correlation analysis of quality indexes and geographical coordinates and correlation analysis of the seven quality indexes were also performed. The results showed that： quality differences between ＂Nagafu 2＂ apple from different habitats were obvious, especially for fruit index, peel color value, total acid content and TSS-Acid ratio. Correlation analysis of quality indexes and geographical coordinates revealed that： fruit index and fruit firmness showed negative correlation with longitude significantly; fruit firmness and total acid content showed positive correlation with altitude extremely significant; TSS-Acid showed negative correlation with altitude significantly. It proved that growing location of the same apple breed affected fruit quality. Correlation analysis of the seven quality indexes revealed that： single fruit weight showed significant positive correlation with fruit index, soluble solids content and total acid content respectively; single fruit weight, fruit firmness and soluble solids content all showed positive correlation with total acid content significantly.关键词
