以国外主推番茄品种好韦斯特（不抗TYLCV）为对照，比较了其与自育高抗TYLCV番茄品种---瓯秀806的叶绿素含量、植物学特性、光合特性等生理特性的差异，结果表明，Chla、Chlb、Chl （a＋b）和Car含量均以瓯秀806较高（P＜0.05）；而Chla /Chlb则以好韦斯特较高（P＜0.05）；2个番茄品种的光合速率均随着CO2浓度的升高而增大，当CO2浓度大于450μmol?mol-1，其光合速率增加不显著（P＞0.05）。在低CO2浓度（350μmol?mol-1）下，好韦斯特的最大光合速率较高（P＜0.05）；较高CO2浓度（450，550和650μmol?mol-1）下，好韦斯特的光饱和点均较低（P＜0.05），分析认为主要由于其较低的叶绿素含量引起。而不同CO2浓度下，2个番茄品种表观量子效率（AQY）、暗呼吸速率（Rn ）和光补偿点（LCP）差异较小。瓯秀806早期产量为1456.8 kg?667 m-2，低于好韦斯特（P＞0.05）；而其总产量则高于好韦斯特，达7245 kg，增产58.2％（P＜0.05），分析其原因主要是由于好韦斯特后期发病率较高。

The content of chlorophyll content , the botany characteristics and photosynthetic characteristic of Ouxiu 806 (variety A) and Haoweisite (variety B) were compared, the results showed that the content of Chla , Chlb and Chl(a+b) of variety A were higher (P<0.05), while the Chla /Chlb ratio was lower (P<0.05).The photosynthetic rate of two varieties increased with increasing CO 2 concentration, and there was no significant difference under higher CO 2 concentrations of 450, 550 and 650 μmol? mol-1 .At low CO2 concentration (350 μmol? mol-1 ), the maximum photosynthetic rate of variety B was higher (P<0.05).At high CO2 concentrations (450, 550 and 650 μmol?mol-1 ), the light saturation point of variety B was lower (P<0.05), which might be caused by the lower content of Chla, Chlb and Chl(a+b) in variety B.There was no significant difference in apparent quantum efficiency (AQE), dark respiration (Rn ) and light compensation point (LCP).The early yield of variety A was 1 456.8 kg?667 m-2 , lower than variety B (P>0.05), but the total yield was significantly higher in variety A , which was 7 245 kg, 58.2%higher than variety B, which could be due to the higher incidence of TYLCV in variety B in the later period .
