Abstract The photosynthetic and morphological characteristics, and microstructure of roots and shoots, were studied between columnar apple and standard apple trees derived from the crosses of ‘Fuji’ × ‘Telamon’ and ‘Gala’ × ‘Telamon’. The results showed that chlorophyll A, chlorophyll B, the content of chlorophyll A+B, and leaf area index were higher in columnar apple trees than in standard apple trees. In a day cycle, the net photosynthetic (Pn) and transpiration rates (Tr) were higher in the columnar apple trees than in standard apple trees. The daily variations of Pn and Tr were of a double… More >
