9个沙地李品种经济性状的综合评价
|
摘要
为给经济性状优良并适宜于川灌区推广的李良种的筛选提供参考依据,以种植于沙地的黑宝石李等9个李品种为研究对象,对其主要经济性状指标(平均单株产量、平均单果质量、最大单果质量、果实中可溶性固形物的含量、果实色泽、成熟期、果实风味、耐贮性)进行了测定与分析,并采用主成分分析法对9个李品种的经济性状表现进行了综合评价。结果表明,9个李品种经济性状的个体差异显著,其经济性状由优到劣依次为:巨王李>黑宝石李>红宝石李>美国蛇李>幸运李>日本早红李>月光李>绥李三号>大石早生,其中,巨王李、黑宝石李、红宝石李和美国蛇李等品种的表现均较优良。
In order to provide some references for selection of plum cultivars with good economic characteristics and suitable for being planted at plain irrigation areas, Friar Plum and eight other cultivars in sandy lands were selected as study subjects, some main economic characteristics(average yield per plant, average single fruit mass, maximum single fruit mass, soluble solid content in fruit, fruit color and luster, harvest period, fruit flavor, storability) of these cultivars were determined and analyzed, and the economic characteristics of the nine plum cultivars were comprehensively evaluated by using principal component analysis(PCA). The results showed that economic characteristics had significant differences among the nine cultivars, and the order of the cultivars based on economic characteristics from fine to inferior was Giant King Plum > Friar Plum > Ruby Plum> American Red Delicious Plum > Lucky Plum > Japanese Early Red Plum > Moonlight Plum > Sui Plum No.3 > Dashi Early Ripening Plum. Among them, Giant King Plum, Friar Plum, Ruby Plum and American Red Delicious Plum had better performance.
