| Abstract: | 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 (Fv/Fm, 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. |
