以７．８７μｍｏｌ·Ｌ＾－１超氧化的歧化酶模型化合物浸种７２ｈ，并于低温胁迫前２４ｈ喷洒幼苗１次，能有效地提高水稻幼苗对５±１℃低温的抵抗力，促进低温腔迫后在２５／１８℃下的恢复生长。经处理的幼苗存活率提高２１．６％，幼苗高度，根长和根数均高于对照。

Binuclear Copper(Ⅱ)Model Compound of Superoxide Dismutase(SODMC),a complex synthesized according to the structure of active site of natural SOD,has been found to possess excellent SOD activity in vitro.The effects of SODMC on the chilling-resistance of rice seedings is investigated in this paper.The results indicated that the chilling-resistance of rice seedlings was enhanced remarkably by soaking the seeds and spraying the seedlings(when 2cm high)with 7.87 umol·L(-1)SODMC 24h before chilling (5℃±1℃,72h).SODMC also improved the growth of c...
