(…)选取完全展开叶片的初始荧光与峰值荧光之比（Fo: Fp）作为植物健康状况的指标。低温胁迫诱导了Fo: Fp的增加，这与植物对低温胁迫的敏感性有关。经冷处理的茄类番茄红素和f1杂交种的Fo: Fp值保持在较低水平，几乎没有表现出与冷相关的损害症状，而基本上不耐低温的商品品种的Fo: Fp值大幅增加（…）
(...) The ratio of the initial to the peak fluorescence (Fo : Fp) measured from fully expanded leaves was chosen as an indicator of plant health. Chilling induced an increase in Fo : Fp that was correlated with the sensitivity of the plant to low-temperature stress. Values of Fo : Fp remained low for cold-treated Solanum lycopersicoides and the F 1 hybrid, which showed few symptoms of chilling-related damage, whereas the commercial cultivars, which were essentially intolerant to low temperatures had large increases in Fo : Fp (...)
