Effect of Selenium Enrichment on the Growth, Photosynthesis and Mineral Nutrition of Broccoli
Broccoli is placed in primary selenium (Se) accumulator group plants, which is considered as an important source of Se for providing human daily need. This experiment used an outdoor hydroponic system to evaluate the effects of Se foliar application at the rates of 0, 10, 50, and 100 μg Se/ml concen...
