以5年生～6年生梨枣、金丝小枣和陕抗2号为试材，研究了枣树枝叶含水量的变化规律和差异。试验结果表明：1）枣树枝条含水量周年变化中表现出各自不同的特点。枣树枝条总含水量和自由水含量表现出先升后降的趋势，峰值出现在6月；束缚水含量变化趋势为先上升后保持平稳。2）枣树叶片在幼叶期总含水量和自由水含量逐渐降低，束缚水含量逐渐增加，进入成熟期后水分含量均保持平稳。叶片束缚水含量在6月期间出现较高值。3）枣树枝条束缚水含量与叶片总含水量和自由水含量呈显著或极显著负相关，与叶片束缚水含量呈极显著正相关。4）不同品种枣树含水量在萌芽期、花期和休眠期，存在不同程度的差异。

Five or six year-old Z. Jujuba cv. Jinsixiaozao, Z. Jujuba cv. Lizao and Z. Jujuba cv. ShankangNo. 2 were a- dopted to study the change of the water content of Z. Jujuba. The main results were as follows : ( 1 ) Water content in branch of Ziziphus jujuba had different characteristics. The TWC and FWC showed a peak in June and the BWC tended up- wards and then kept stable in branch. (2) The TWC and FWC in leaves decreased during young leaves period and BWC gradually increased. At mature stage, the water content remained stable, but the BWC in leaves was relatively high value in June. (3) The BWC in branch was significantly negatively correlated with TWC and FWC in leaves and was significantly positively correlated with BWC in leaves. (4) Water content of different species of Ziziphus jujuba were different at germi- nation, flowering and dormancy stage.
