摘要

尽管番茄红素含量在番茄种质(本地和外来)与番茄花叶病毒(ToMV)分离物进行了比较，使用当地首选的杂交品种，即格兰德河作为对照。利用分光光度法和反相高效液相色谱法测定了番茄抗ToMV基因型中总类胡萝卜素和番茄红素的含量。我们的数据表明，病毒感染显著降低了番茄果实中总类胡萝卜素和番茄红素的含量。在当地栽培的格兰德河杂交品种中，受感染番茄的番茄红素含量明显低于健康番茄。遗传资源GT-47 (CLN-2123-E)的番茄红素含量与健康番茄相比下降了60%。然而，病毒感染对ToMV感染番茄基因型基于dpph的抗氧化潜能的有害影响较小。

Infection with Tomato Mosaic Virus Reduces Lycopene Accumulation in Tomato Fruits

Despite Lycopene content in tomato germplasm (both local and exotic) was evaluated against isolates of tomato mosaic virus (ToMV), using a locally preferred hybrid i.e., Rio Grande as a control. Promising lines with resistance to ToMV were assessed by total carotenoid and lycopene content in virus-challenged tomato genotypes using spectrophotometry and RP-HPLC. Our data showed that virus infection significantly lessens the total carotenoid and lycopene content in tomato fruit. Lycopene content was significantly reduced in infected tomato compared to healthy, in locally cultivated hybrid Rio Grande. The germplasm GT-47 (CLN-2123-E) showed 60% decrease in lycopene content in infected tomato when in comparison to healthy produce. The virus infection, however, exhibited less deleterious effect on DPPH-based anti-oxidant potential of the ToMV infected tomato genotypes.
