| 摘 要： | 在贵州省遵义市、长顺县及威宁县3个不同海拔示范园,对新嘎啦、富士2001及红王将3个苹果品种的光合特性进行了研究.结果表明:随着海拔的升高,3个品种的光合能力呈现出增强的趋势,相同光强下,威宁的净光合速率(Pn)最高.3个品种在不同海拔示范园的光合能力差异较大,其Pn-PAR响应曲线,除富士2001、红王将在长顺为抛物线外,均为对数函数;Pn-T响应曲线均为抛物线,最适温度在不同海拔存在一定差异,为25.4℃~30.7℃;Pn与气孔导度均呈显著相关,与胞间CO2浓度呈显著负相关,与蒸腾强度在威宁达到显著相关,与相对湿度相关性不显著.高海拔的威宁对3个品种的栽培具有生态优势,而新嘎啦在3个海拔高度的光合能力强于其余二品种.

| Abstract: | To provide the ecological basis for the extension of apple cultivation in Guizhou Province,three apple cultivars,New Gala,Fuji 2001 and Benishogun,grown in Zunyi City,Changshun County and Weining County,were used as experiment materials to investigate the effects of different altitudes on the photosynthetic characters of the apple trees.The results showed that the photosynthetic capacities of the trees tended to increase with the altitude and,with similar light intensity,New Gala in Weining showed the highe... |
