【摘要】 以6个不同熟性加工番茄品系为试材,在每个品系的第2穗花开放时做出标记,在开花后的第45天果实定个初红时第1次取样,采用国标法分别测试果实的主要品质指标,每7d取样1次,比较6个品系主要品质性状动态变化情况,用方差分析法对比了各品质最优值与常规测试时间第80天的值,从而得出各品系主要品质最优值的出现时间。结果表明:番茄红素含量最大值出现在第66天,可溶性固形物含量最大值出现在第59天,可滴定酸含量最小值出现在第80天,单果重含量最大值出现在第66天,干物质含量最大值出现在第80天,a/b色差比最大值出现在第66天。在各品质出现峰值时进行测试,以期为不同加工番茄新品种选育的最佳时间提供参考。更多还原

【Abstract】 Six different processing tomato strains were used as materials,marking each strain when the second spike flowering.After flowering 45 days,samples were taken when fruit fruiting,the main quality indexes were determined of every 7days sampling once,dynamic change of main quality traits were compared,the quality of the optimal values compared with conventional test time on the 80 ^th day were conducted by variance analysis,to require the optimal time that emerge the best quality.The results showed that,lycopene content was achieved maximum on 66 ^th day,total soluble solids content was achieved maximum on 59 ^th day,titratable acid content was achieved minimum on 80 ^th day,weight of single fruit achieved maximum on 66 ^th day,dry matter content was achieved maximum on 80 ^th day,a/b color difference was achieved maximum on 66 ^th day.Testing the quality at the peak of emergence time was to provide reference for the best time for breeding processing tomato varieties.更多还原
