| 摘 要： | 用CIRAS-1 便携式光合作用测定系统研究了豆梨(Pyrus betulaefolia Bunge) 、杜梨(P.calleryana Dcen.) 幼树以及豆梨、杜梨与砂梨(P. pyrifolia Nakai) 品种丰水、新高4 种砧穗组合幼树叶片的光合作用。结果表明, 砧木显著影响栽培品种的光合作用, 杜梨比豆梨以及以杜梨为砧木的丰水、新高幼树比以豆梨为砧木的两品种幼树叶片净光合速率(Pn) 、表观量子产量(Φi) 、羧化效率(CE) 、水分利用效率(WUE) 高。新高的Pn、Φi 、CE 和WUE 值较丰水高, 且在两种砧木上均表现出同样的结果。

| Abstract: | In this paper a comparison of the photosynthetic characteristics among pear rootstock Pyrus betulae folia Bunge and P. calleryana Dcen. , four combinations of two pear varieties Hosui and Niitaka on the above two rootstocks is presented. Results showed that the value of net photosynthetic rate ( Pn) , apparent quantum yield (Φi) , carboxylation efficiency (CE) , and water use efficiency (WUE) of P. calleryana Dcen. , Hosui or Niitaka on P. calleryana Dcen. , Niitaka on either P. calleryana Dcen. or P. betulaefolia Bunge was all higher than that of the above four physiological indices of P. betulaefolia Bunge , Hosui or Niitaka on P. betulaefolia Bunge , Hosui on either P. calleryana Dcen. or P. betulaefolia Bunge respectively. |
