水杨酸和盐浸种对香稻和非香稻幼苗生理特性的影响
Effects of Pre-soaking with Salicylic Acid and Salt on Some Physiological Characteristics of the Aromatic and Non-aromatic Rice Seedlings
摘要
Abstract
The purpose of this study was to investigate the effects of salicylic acid ( SA) and salt on some phys-iological characteristics of aromatic and non-aromatic rice seedlings .Aromatic rice Nongxiang 18 and non-aromatic rice Huahangsimiao were used as materials ,seed pre-soaking treatments were SA treatment ( Seeds soaked in 0 and 1 mmol/L of SA) and salt treatment(Seeds soaked in 0 and 50 mmol/L of NaCl).The SOD activity,POD activity, soluble protein content ,proline content ,MDA content in leaves and culm and sheath of rice seedling and 2-AP con-tent in leaves and culm and sheath of aromatic rice were studied .The results showed that SA ,NaCl and SA+NaCl treatments significantly increased 2-AP content in aromatic rice seedling .The 1 mmol/L SA +50 mmol/L NaCl treatment significantly increased proline content in aromatic rice seedling ,no significant difference was observed in non-aromatic rice;50 mmol/L NaCl treatment significantly increased POD in culm and sheath of aromatic rice and non-aromatic rice seedling ,and significantly increased SOD increased in aromatic rice seedling;1 mmol/L SA treat-ment significantly increased proline content in leaves of both aromatic rice and non-aromatic rice seedling ,and sig-nificantly increased POD activity in aromatic rice seedlings.These results indicated that the SOD, POD activity and proline content in rice seedlings were the main index respond to pre-soaking by SA and salt .SA relived salt stress and significantly increased 2-AP.关键词
