| 摘 要： | 通过溶液培养，研究了不同浓度融雪剂对水稻幼苗生长及部分生理特性的影响。结果表明：在高浓度的融雪剂胁迫下水稻幼苗苗高和根长变小，植株生长受到抑制，低浓度（质量浓度为0．1g，L）融雪剂处理后叶绿素含量略有增加，高浓度的融雪剂处理后叶绿素的含量大幅度下降。质量浓度高于1g，L的融雪剂处理水稻幼苗，根部可溶性糖的含量急剧上升，叶片膜脂过氧化产物MDA含量增加，同时膜受到损伤膜透性增大。

| Abstract: | Nutrient solution culture experiment was conducted to study the effect of snow-melting agent treatment(0,0.1,0.5,1.0,2.0,4.0 g/L) on plant growth and some physiological characteristics of rice seedlings.The results showed that high concentration snow-melting agent inhibited the increase of plant height;low concentration of snow-melting agent(0.1 g/L) treatment increased chlorophyll content though high concentration of snowmelt agent(1.0g/L) treatment could reduce it.Additionally,snow-melting agent treatment... |
