摘　　要：以杏李(Prunus domestica×armeniaca)品种味帝为研究对象,设置双因素试验,研究灌溉时间和灌溉量对果实裂果率与品质的影响。其中,灌溉时间设为转色期、始熟期、成熟期;灌溉量(以小区计)分设为80 m3和120 m3。在果实成熟后,检测裂果率与果实硬度、可溶性固形物含量、维生素C含量、可溶性糖含量、可滴定酸含量、钙含量、钾含量、纤维素含量、果胶含量、游离脯氨酸含量等品质指标。结果表明,转色期灌水80 m3的处理的裂果率最低。相关性分析结果显示,果皮、果肉钙含量与裂果率呈显著(P<0.05)负相关。基于测定的品质指标,运用主成分分析法对不同处理的果实品质进行综合评价,发现以转色期灌水80 m3处理的杏李果实品质最优。In order to investigate the effect of irrigation time and irrigation amount on cracking rate and quality of apricot plum(Prunus domestica×armeniaca)fruit,a two-factor test was conducted.The irrigation time was set at the veraison stage,initial mature stage and mature stage,respectively,and the irrigation amount was set as 80 m 3 and 120 m 3 per plot,respectively.The cracking rate and quality indexes of fruit,including fruit hardness and contents of soluble solids,vitamin C,soluble sugar,titratable acid,calcium,potassium,cellulose,pectin,free proline,were analyzed after fruit ripening.It was shown that the lowest fruit cracking rate was achieved by irrigating 80 m 3 at the veraison stage.The cracking rate of fruit was significantly(P<0.05)negatively correlated with the calcium content in peel and pulp of fruit,which was revealed by the correlation analysis.Given the determined quality indexes of fruit,the best comprehensive quality of apricot plum fruit was found under the treatment of irrigating 80 m 3 at the veraison stage,which was calculated by the principal component analysis.
