摘　　要：在迟菜心移栽后用特效植物营养素(SPNE)喷施植株,比较不同喷施次数和对照植株的生物产量、商品产量、种子产量及种子后代幼苗的差异。结果表明,用SPNE喷施2次植株的生物产量、商品产量、种子产量超过用SPNE喷施1次的,用SPNE喷施1次的超过对照(喷施清水);用SPNE喷施2次植株的种子后代幼苗优于用SPNE喷施1次的,用SPNE喷施1次的种子后代幼苗优于未用SPNE处理的对照,表现表观遗传效应。SPNE （Special Plant Nutritional Element） was sprayed to the late flowering cabbage after transplanting, to study the difference of biological yield, commodity yield, seeds yield and seedling at next generation. The results showed that the biological yield, commodity yield, seeds yield and seedling at next generation of plants treated by SPNE for two times were better than the plants only treated by SPNE for one time. The above index of plants treated by SPNE for one time were better than the contrast. And it showed epigenetic effects.
