西红柿是人类饮食中番茄红素的重要来源。以温室栽培的2个番茄品种为研究对象，研究了温度（15℃~ 24℃）、co2供给量（380 ~ 1000ppm）和营养液电导率（EC, 2 ~ 9ds m -1）对番茄类胡萝卜素（番茄红素、s-胡萝卜素）含量的影响。樱桃番茄品种Supersweet的特点是番茄红素含量高于传统的圆形番茄Counter。结果表明，温度对成熟过程中番茄红素和s-胡萝卜素的生物合成有显著影响。在被调查的品种中，20℃以上的温度似乎是番茄红素生产的最佳温度，而降低到15℃则会降低番茄红素含量。在所调查的条件下，CO 2供应和EC的增加都没有影响类胡萝卜素的含量。
Tomatoes are an important source of lycopene in the human diet. The effect of temperature (15°C - 24°C), CO 2 supply (380 - 1000 ppm) and nutrient concentration measured as electrical conductivity of the nutrient solution (EC, 2 - 9 dS m -1 ) on the content of carotenoids (lycopene, s-carotene) were investigated in two tomato cultivars grown in a greenhouse. The cherry tomato cultivar Supersweet was characterised by higher lycopene contents than the conventional round tomato ‘Counter’. The results indicated that temperature has a significant influence on the biosynthesis of lycopene and s-carotene during ripening. A temperature above 20°C seems to be optimal for lycopene production in the investigated cultivars, whereas a decrease to 15°C diminished the lycopene content. Neither CO 2 supply nor EC increase affected the carotenoid content under the conditions investigated.
