| 摘 要： | 实验研究了铈的不同施用方法对盐(NaCl)胁迫下玉米幼苗保护酶系统的影响。结果表明:根施20 mg/L铈和喷施30 mg/L铈对盐胁迫下玉米幼苗的防护效应较好,使超氧化物歧化酶(SOD)和过氧化物酶(POD)活性下降,过氧化氢酶(CAT)活性上升。说明稀土元素铈能在一定程度上减轻盐对玉米幼苗造成的伤害。

| Abstract: | This study applied different methods of cerium on maize seed germination and seedling growth under salt stress. The results showed that root 20 mg/L Ce and spray 30 mg/L Ce on maize seedlings under salt stress with the best protective effect, SOD and POD activity decreased, CAT activity increased. The concentration of different maize seedlings will result in varying degrees of damage, and rare-earth element cerium can improve to some extent this phenomenon. |
