摘要: Silicon (Si) is a beneficial element for plants and can increase plant resistance. In the present work, a hydroponic experiment was carried out to study the effects of Si on the growth and photosynthesis of rice (Oryza sativa L.) seedlings under simulated acid rain (SAR) stress. The growth, photosynthesis and chloroplast ultrastructure of rice seedlings treated with combined or single weak SAR (pH 4.0) and/or Si (1, 2 or 4 mM) were improved. Spraying with moderate or severe SAR (pH 3.0 or 2.0) significantly inhibited the growth and …
