| 摘 要： | 以骏枣为对象,分别测定其上部,中部和下部枣吊叶片的净光合速率和叶绿素含量。结果表明:枣吊不同叶位的净光合速率(Pn)随叶位的增加不断降低,4~7位叶片的Pn值可以反映整个枣吊的光合能力;在冠层分布上,Pn值,上部枣吊>中部枣吊>下部枣吊;枣吊中部位置的叶绿素含量相对稳定,能够反映整个枣吊叶绿素相对含量,且叶绿素相对含量与净光合速率呈正相关。

| 关 键 词： | 叶位 净光合速率 叶绿素相对含量 枣吊 骏枣 |

| Abstract: | Used ’Junzao’Jujube as materials,studied the net photosynthesis rate and chlorophyll content of ’Junzao’Jujube leaves.The results showed that the Pn of lower position was the highest,secondly was in mid-position,the upper-position was the lowest,the Pn of 4～7 position could reflect the photosynthetic capacity of bearing branch,distribution in the canopy,the upper bearing branch had higher Pn than central and lower bearing branch;The chlorophyll content of mid-position was stability;chlorophyll content and photosynthetic rate were positively correlated. |

| Keywords: | leaf position chlorophyll content photosynthesis characteristics bearing branch \'junzao\'jujube |
