低磁场磁化水对涡虫无性生殖的影响观察

An Observation of the Magnetism Treatment Water Affecting Dugesia Japonica Asexual Reproduction

水经低磁场处理后，其不同磁化时间对涡虫（Ｄｕｇｅｓｉａ ｊａｐｏｎｉｃａ）无性生殖的影响表现为２ｈ、９ｈ有抑制作用，６ｈ促进生殖，４ｈ、１５ｈ影响不明显。促涡虫无性生殖的最佳磁场＞４０ｍＴ，无性生殖的最适温度２５．５℃。

The influence of different time of magnetising water on Dugesia japonica asexual reproduction shows as follows: for 2 or 9 hours, the water restrains the reproduction;for 6 hours, it accelerates the reproduction; for 4 hours or 15 hours, it does not have any obvious influence. The best magnetic field for Dugesia japonica asexual reproduction is larger than 40mT and the most suitable temperature for it is 25.5℃。
