To study the impacts of nanometer pottery trays （NPTs） on different rice varieties, three rice varieties, Zhongzheyou 1, Jinzao 47 and Xiushui 09, were treated with four NPTs （NPT-A, NPT-B, NPT-C and NPT-D） with different energies, respectively. The results showed that when the same rice variety was treated with different NPTs or different rice varieties were treated with the same NPT, the impacts on seed germination rate, seedling growth, plant height, panicle length and weight, the number of filled grains, seed-setting rate and 1000-grain weight varied between different rice variety-NPT interaction groups. In general, high energy NPT-C and NPT-D treatments obviously enhanced the functions of most examined rice characters. For example, NPT-C and NPT-D treatments improved the germination rate of all the three rice varieties, and promoted the root growth of seedlings, and increased seedling fresh weight, single panicle weight, filled grain number per panicle, seed-setting rate and 1000-grain weight. On the contrary, low energy NPT-A treatment restrained the seed germination rate in Jinzao 47 and Zhongzheyou 1, and decreased the seedling fresh weight in Zhongzheyou 1. NPT-B treatment restrained the seedling growth in Jinzao 47 but increased the panicle length of Zhongzheyou 1. NPT-A and NPT-C treatments obviously decreased the 1000-grain weight in Xiushui 09. Therefore, when treating crop seeds or plants using nanomaterials or nanotechnologies, different types of crops/varieties should select the nanomaterials or nanotechnologies with suitable energies to reduce the negative effects.
