摘　　要：为阐明樱桃番茄整枝方式对冠层内光合有效辐射截获和荧光特性及产量的影响,以香妃3号为试验品种,设置4种整枝方式,测定樱桃番茄冠层光截获特性、荧光特性、冠层微环境以及植株生长状态和最终产量。结果显示,针对群体冠层光截获,三杆整枝处理的光合有效辐射(IPAR)和光截获率(CaR)显著(P<0.05)高于其他处理,光透射率(PeR)显著(P<0.05)低于其他处理。针对叶片荧光特性,三杆整枝处理的叶绿素荧光参数F_(v)/F_(m)和qP相对于其他处理均有不同程度的提高。同时,三杆整枝处理的地上部生长形态、冠层微环境和产量均显著优于其他处理。研究表明,三杆整枝最利于形成合理的个体构型和群体空间排布,从而提高樱桃番茄的光能作用、生长状态和产量。To elucidate the effects of prunning patterns on canopy photosynthetically active radiation,chlorophyll fluorescence parameters and yield,Xiangfei No.3 was selected as the experimental material,four levels were set for prunning patterns,canopy light interception characteristics,chlorophyll fluorescence characteristics,canopy microenvironment,growth indices and yield of plants were measured.As a result,in terms of colony canopy photosynthetically active radiation,the photosynthetic effective radiation(IPAR)and light interception rate(CaR)of plants in the three-bar prunning treatment was significantly(P<0.05)higher than other treatments,light transmittance(PeR)was on the contrary.In terms of leaf photosynthetic fluorescence characteristics,chlorophyll fluorescence parameters(F_(v)/F_(m),qP)had different degrees of improvement than other treatments.At the same time,plants growth indices,canopy microenvironment and yield of three-bar prunning treatment was significantly(P<0.05)higher than other treatments.It can be seen that three-bar prunning was the most beneficial to form a reasonable individual configuration and population space arrangement,so as to improve the photosynthesis,growth status and yield of cherry tomato.
