2316 samples of weed seeds of Japan were collected and stored in a refrigerator room of -20 degrees of Celsius. They belong to 845 species of 89 families. The samples include most of the weed species of Japan.A wind-operated machine to select ripe seeds is very useful. Number of seeds in a fruit was counted and weight of seeds were measured.After dehumidifying seeds with desiccator, seeds were stored in a refrigerated room of minus twenty degrees of Celsius. Seeds of the most of the species are safely stored by this method. Some seeds of aquatic plant died after drying them. Such a kind of seeds are stored in the water and kept in a refrigerator of four degrees of Celsius.All data measured about seeds are stored as a database in a personal computer.

采集日本杂草种子样品2316份，保存在-20 ℃的冷藏室中。它们隶属于89科845种。这些样本包括日本的大部分杂草物种。选择成熟种子的风力机器非常有用。用干燥器对种子进行除湿后，将种子储存在零下20摄氏度的冷藏室中。大多数物种的种子都是通过这种方法安全储存的。一些水生植物的种子在干燥后死亡。这种种子被储存在水中，并保存在四摄氏度的冰箱中。所有关于种子的测量数据都作为数据库存储在个人电脑中。
