| 摘 要： | 以番茄为试验材料,研究番茄黄化曲叶病毒(TYLCV)侵染对植株叶片叶绿素含量、净光合速率、气孔导度、胞间CO2浓度和叶绿体超微结构的影响.结果表明:TYLCV侵染番茄后,叶片叶绿素a、b以及总叶绿素含量分别下降50.2%、24.19%和43.84%,叶片净光合速率和气孔导度分别下降43.28%、27.07%,胞间CO2浓度增加13.04%.与健康叶片相比,叶绿体变形,叶绿体基质片层大部分消解,基粒结构消失,叶绿体外膜和内膜剥离,质壁分离和细胞膜内陷,细胞器消解.研究表明,TYLCV侵染破坏了番茄叶片的叶绿体结构,严重影响番茄叶片的光合作用. |

| Abstract: | The effect of tomato yellow leaf curl virus(TYLCV) on chlorophll content,net photosynthetic rates(Pn),stomatal conductance(Gs),intercellular CO2 concentration(Ci) and chloroplast ultra-structure were studied.The results showed that,compared with the healthy leaves,the chlorophll a,b and a+b of diseased leaves reduced 50.2%,24.19% and 43.84%,the Pn and the Gs of diseased leaves decreased 43.28%,27.07%,but the Ci of diseased leaves increased 13.04%.The ultra-structural analysis showed that the chloroplast in ... |
