摘要： 从国内外搜集了8个番茄品种，测定其低温雾霾后生理生化及田间抗病性、产量及品质等指标。结果表明：低温雾霾天气期间，日光温室自身的环境条件远远不能满足番茄对温、光、湿度的需求。在逆境条件下，不同品种番茄自身抗病性较强的品种有金鹏8号和粉宴1号，其落果率为2.5%，3.7%；死秧率分别为38.8%，25%；发病率为35.5%，35%，这几个指标与其他品种比较均在较低水平。且金棚8号产量最高，为54 300 kg/hm²，其次为粉宴1号、T1701，产量均在50 000 kg/hm²以上。果实品质，金鹏8号的糖酸比值最大，其口感最好；粉宴1号的硝酸盐含量最低。整个雾霾天气，叶绿素降幅最小的品种为金鹏8号，其次为粉宴1号；生理生化指标，SOD值和POD值较大，可溶性糖和脯氨酸含量积累较多的品种也是金鹏8号、粉宴1号；丙二醛含量在此试验中，品种之间的差异不明显。故在低温寡照条件下，自身调节性，适应性较强的品种有金鹏8号、粉宴1号；生理指标检测结果与田间试验结果相吻合。

Abstract: This experiment consists of eight varieties of tomato were collected from home and abroad,the indexes of physiological and biochemical characteristics,field resistance,yield and quality were determined after the haze.The results showed that:during the weather of low temperature and haze,solar greenhouse's own environmental conditions far could not meet the requirements of the temperature,light and humidity of tomato.Under stress conditions,the varieties with stronger resistance were Jinpeng No.8 and Fenyan No.1,their fruit drop rates were 2.5%,3.7%,dead rates of plant were 38.8% and 25.0%,the diseases incidence rates were 35.5% and 35.0% respectively,These indicators were in the lower level than other varieties.And Jinpeng No.8 had the highest yield,54 300 kg/hm²,followed by Fenyan No.1and T1701,which production were more than 50 000 kg/hm². Fruit quality,the maximum of sugar acid ratio was Jinpeng No.8,and the taste was best;The minimum of the nitrate content was Fenyan No.1.The whole fog and haze,the smallest decrease amplitude of chlorophyll was Jinpeng No.8,Fenyan No.1 wasthe second.Physiological and biochemical indexes,the varieties of accumulated more contents of soluble sugar and proline were Jinpeng No.8,Fenyan NO.1,the value of SOD and POD were also higher,The content of MDA didn't have obvious differences between species in this experiment.Therefore,under low temperature and weak light,the varieties with self-regulation,strong adaptability were Jinpeng No.8,Fenyan NO.1,which results of physiological indexes were consistent with the results of field experiments.
