摘要
The effect of applying brassinosteroids to seeds on growth, pigment levels and nitrate reductase activity of rice ( Oryza sativa L.) plants grown on saline substratum was investigated. Brassinosteroids reduced the impact of salt stress on growth, considerably restored pigment levels and increased of nitrate reductase activity.
