【摘要】 选取河北省农林科学院经济作物研究所新配置的16个番茄F1组合为试材,以国内生产上应用的中果型硬粉果品种冀番135为对照,利用质构仪研究了上述番茄生长过程中质构硬度的变化.结果表明:不同生长阶段番茄果实硬度差异显著;16个不同番茄F1青果期和红果期果实硬度差异显著;番茄F1红果期果实硬度与青果期果实硬度极显著正相关;番茄F113#在青果期和红果期硬度都最大,并且在采后贮藏期其果实硬度比国内生产上应用的中果型硬粉果品种冀番135的大,耐贮运性能好,是硬粉果番茄选育的理想品种.更多还原

【Abstract】 The hardness of tomato fruit is an important indicator of storability and breeding.In the project,the change of hardness degree in the growth process of the above tomato has been studied with the texture analyzer,with 16 tomato F1 combination newly bred by the Institute of Cash Crops of Hebei Academy of Agriculture and Forestry Sciences as the test materials,with the small-fruited hard powder fruit variety of JF 135 that has been applied in the domestic production as the control.The results show that the tomato fruits in the different growth stages show significant difference in hardness;16 different tomatoes F1 show significant difference in hardness in the green fruit period and the red fruit period;tomato F113# has the greatest hardness in the green fruit period and the red fruit period,it has greater hardness in the post-harvest storage period than that of the small-fruited hard powder fruit variety of JF 135 that has been applied in the domestic production,and it has good storability and transport performance,thus it is the ideal bred variety of hard powder fruit tomato.更多还原
