摘要
对成年银杏花粉特性进行了初步研究。内容包括不同优树间小孢子叶球和花粉的形态变异，短枝直径对小孢子叶球数的影响，不同树冠部位枝条上花粉产量的差异，花粉中有机养分和矿质营养元素含量的变异等。结果表明：（１）树龄和树冠部位对上述指标有明显的影响；（２）不同优树间上述指标有显著差异；（３）一些微量元素明显高于其他一些树种。
The following parameters were investigated:size of catkin,pollen,and short shoot,the number of catkins per short shoot,the amount of pollens per catkin,The paper reported the results about characteristics of mature maidenhair trees pollens,content of organic substances and mineral elements.The results showed that①tree age and crown location had a significant effects on the above values,②there was remarkable difference concerning those parameters,and ③ content of microelements in Ginkgo biloba was much higher than some other tree species.
