摘要
选取陕西省6个不同苹果生产基地县为试验地点,比较和分析了不同产地的"富士"、"嘎啦"、"秦冠"和"玉华早富"4个主栽品种的品质差异及其指标间的相关性。结果表明:苹果果形指数与单果重、果皮黄色度值b*与果皮亮度值L*、可滴定酸含量与果皮红色度值a*呈极显著正相关,其相关系数分别为0.785、0.582和0.507;硬度与单果重、硬度与果形指数、果皮红色度值a*与果皮亮度值L*、果皮黄色度值b*与果皮红色度值a*、固酸比与果皮红色度值a*、固酸比与可滴定酸含量呈极显著负相关性,其相关系数分别为-0.487、-0.552、-0.703、-0.728、-0.576和-0.895。表明陕西省不同产地苹果主栽品种基本品质指标间存在着显著差异。
The basic quality indexes of ＇ Fuji ＇, ＇ Gala ＇, ＇ Qinguan＇, ＇ Yuhuazaofu ＇ apple from six different habitats of Shaanxi province were determined and correlation analysis of quality indexes were performed. The results showed that quality differences between four cultivars from six different habitats were obvious. Correlation analysis of quality indexes revealed that, the significant correlation was found between fruit index and single fruit weight,the rind yellowness and the rind brightness,titratable acid content and the rind redness,soluble solid content and single fruit weight,soluble solid content and fruit index,the rind redness and the rind brightness,the rind yellowness and the rind redness,solid acid ratio and the rind redness, solid acid ratio and titratable acid content, and the correlation coefficient were up to 0. 785,0. 582, 0. 507,--0. 487,--0. 552,--0. 703,--0. 728,--0. 576 and --0. 895. It suggested that the main quality indexes of the main apple cultivars from different habitats of Shaanxi had significant difference.
