摘要:
由于育种目标过度偏向外观与耐贮运性,当前鲜食番茄外观艳丽,但果肉硬、味道淡、营养寡,究其原因是缺乏综合性的品质评价体系。为了更全面科学地评价番茄品质,本文创新性地引入了在临床医学、教育等领域行之有效的评价体系构建策略。首先对鲜食番茄品质的定义及构成进行了系统性综述,基于德尔菲法对国内27名从事番茄育种及品质研究领域的专家,进行了2轮意见征询,形成了1套包含3个品质维度(风味品质、营养品质、商品品质)、15个品质指标的鲜食番茄评价框架。2轮专家函询的积极系数分别为85.2%和86.0%,专家权威系数平均值为0.9,表明了专家们对本研究的高度重视和专业权威性,结合层次分析法对15个品质指标进行了权重分配[酸甜味8.16%、香味5.91%、鲜味6.47%、负面味道7.49%、汁水量6.43%、化渣度6.47%、质地6.41%、可溶性固形物含量6.87%、类胡萝卜素含量6.82%、维生素C(VC)含量6.58%、硬度6.15%、果形7.24%、果面光泽度6.92%、果实着色均匀程度6.59%、萼片有无及大小状态5.49%],为番茄品质育种及研究工作提供参考。
