In the first generation, conventional rice cultivars were treated with SPNE and clean water, respectively; in the second generation, conventional rice cultivars were divided into four groups： （1） SPINE spaying in the first-generation and SPNE spaying in the second-generation; （2） clean water spaying in the first-generation and SPNE spaying in the second-generation; （3） SPNE spaying in the first-generation and clean water spaying in the second-generation; （4） clean water spaying in the first-generation and clean water spaying in the second-generation. The results showed that SPNE could improve fresh grain yield and dry grain yield of rice ; especially, dry grain yield of rice was improved more than fresh grain yield. Comparison results of two conventional rice cultivars in four groups confirmed that SPNE has epigenetic effects on rice in the second generation, thus improving the yield traits, chlorophyll content, protein content, amylase activity, peroxidase （POD） activity and superoxide dismutase （SOD） activity compared with control. Both these two conventional rice cultivars exhibited the best results in SPNE treatment. SPNE showed consistent trend of epigenetic effects on different rice cultivars but led to slightly different results.展开更多
