镁含量最高的是沙拐枣（1.67%），最低的是麻黄和灌木铁线莲，均为0.11%；

Calligonum mongolicum Turcz . had the highest Mg content ( 1.67 % ), Ephedra sinica Stapf and Clematis fruticosa Turcz . had the least one ( 0.11 % );

结果表明，沙拐枣属花粉在形状、大小、沟孔位置及数量、外壁纹饰等方面都十分相似，均为中等大小，3孔沟，穴状纹饰。

It is found that the pollen morphology of Calligonum is rather similar in shape , size , position and number of aperture , and exine sculpture . All of them are medium-sized , 3-colporate ;

沙拐枣幼苗的相对高度生长率和生物量干重对降水量的响应不敏感，但从其幼苗的生长高度和绝对高度生长率来看，沙拐枣幼苗的存活需要较多的水分。

Although the relative height growth rate and biomass of it is not sensitive to water supply , Calligonum mongolicum surviving needs more water supplies , as viewed from growth height and absolute height growth rate .

为了确定沙拐枣植物种子的萌发特性及最优播前预处理方法，在实验室条件下，对10种沙拐枣植物的种子进行了磨砺、硫酸和热水浸泡、冷藏、种子浸出液处理，然后进行发芽实验研究。

In order to determine the optimum seed pre-sowing treatments and patterns of germination , a greenhouse experiment was conducted to study the effects of abrasion , sulphuric acid , boiling water , cold stratification and seed exudate treatments on the germination of ten Calligonum species .
