Abstract: Treated lowland and upland rice seed by the two-pole changed magnetic field, the seedling weight, seedling height, root length and seed vitality are higher than that of untreated ones. The content of the chlorophyll a and b in lowland rice treated is higher, and the fluorescent intensity in extracted solution at 650 nm and 680 nm is lower than that in the untreated; Conversely, thechlorophyll a and b in upland rice treated is lower, and the fluorescent intensity is higher compared to that in the untreated. The conductivity in soaked solution of the lowland rice seed after having been treated is the same with that of the untreated, but in the upland rice is lower than that of the untreated.

Key words: chlorophyll, fluorescent intensity, lowland rice, magnetic field, upland rice, vitality

摘要： 用两极交变磁场对水稻和陆稻各4个品种的种子进行处理，处理种子的发芽特性优于未处理种子，其秧苗高度、鲜重及根长均比未处理的提高。种子经处理的水稻秧苗叶绿素a和b含量较未处理的高，650和680 nm荧光强度较低，而陆稻则相反。磁场处理对水稻种子浸泡液的电导率无显著影响，而陆稻则处理的较未处理的为低。
