| 摘 要： | 以那翁、斯坦勒和佐藤锦3个樱桃栽培品种为材料,利用CIRAS-2便携式光合测定仪,研究了樱桃不同枝条节位、不同叶幕层和方位上叶片的光合特性.结果表明:樱桃新梢不同节位叶片Pn呈单峰变化,中部5~7节叶片Pn值的最高,梢部叶片Pn值最低.不同叶幕层Pn存在显著差异,3个樱桃品种Pn值均为外层>上层>中层>内层.3个品种不同方位叶片Pn值大小均为南面>东面>西面>北面,南面叶片Pn值最高,与其它方位Pn值差异显著.3个樱桃品种间不同叶位Pn值佐藤锦最高,斯坦勒次之,那翁最低.

| Abstract: | Photosynthetic characteristics of leaves at different shoot nodes,canopy layers and leaf positions of three sweet cherry cultivars,Napoleon Bigarreau,Stella and Sato Nishi,were determined by CIRAS-2 photosynthetic instrument.The results showed that the variation of P_n at different leaf nodes on new shoots appeared a single-peak curves,and the P_n of 5~7 shoot nodes was uhe highest.The environmental factors and the developmental level of leaves were the main reasons for the variation.The P_n in different canopy layers appeared significant difference,and the P_n order of canopy layerw is:outer>upper>middle>interior.The P_n of different leaf directions of the three sweet cherry cultivars showed the same tendancy,that is south>east>west>north.The differences of P_n of all sweet cherry leaf positions were correlated with their ecotypes and photosynthetic capability,and P_n of Sato Nishiki was the highest of the three cultivars. |
