测定林木种子生活力,通常采用发芽试验和化学药剂染色的方法。由于需要时间长,用功多,有的还需特殊处理,因而常常不能满足实际工作需要。近几年,我国农、林院校科研部门和部分省市林木种子公司,开始利用软 X 射线摄影检验林木种子。这是目前获得种子内部品质信息、而又不损伤 Determination of tree seed viability, usually using germination test and chemical staining methods. Due to the need for a long time, hard-working, and some need special treatment, which often can not meet the actual needs of the work. In recent years, China’s agricultural and forestry colleges and universities scientific research departments and some provinces and cities forest seed companies, began to use soft X-ray photography tree seed testing. This is the current access to information on the quality of seeds without damage
