氯化铈、硝酸稀土对甘蔗过氧化物酶同工酶和酯酶同工酶的影响

甘蔗分蘖中期以１００、３００、６００ｍｇ／Ｌ质量浓度叶面喷施氯化铈和硝酸稀土溶液，以喷清水作对照，分别于处理后第３ｄ和２０ｄ对甘蔗＋１叶片过氧化物酶和酯酶同工酶作电泳分析，结果表明，单质稀土元素铈和混合硝酸稀土对２种酶的同工酶均有影响，但存在一定差异，在不同浓度处理中，以３００ｍｇ／Ｌ处理结果最为明显，表现为多条酶带的染色加深，１００ｍｇ／Ｌ处理次之，６００ｍｇ／Ｌ处理相对影响较小，稀土元素处理后

Effects of Cerium Trichloride and Rare Earth Nitrate on Peroxidase Isozyme and Esterase Isozyme in Sugarcane

The treatment of spraying cerium trichloride and rare earth nitrate on sugarcane with three concentrations (100, 300, 600 mg/L ) were done at middle tillering stage. The isozyme of peroxidase and esterase of leaf was assayed by means of polyacrylamide gel electrophoresis at the 3th day for the treatment of cerium trichloride and at the 20th day for the treatment of rare earth nitrate. The results showed that both types of rare earth had influences on foe isozyme level, but were different from each other. In the treatments of three concentrations, it was found that the effect of 300 mg/L was most distinct with more enzyme bands coloured deeply, 100mg/L secondly and 600 mg/L indistinct. On zymograms of esterase isozyme and peroxidase isozyme treated with cerium trichloride , the enzyme bands were increased or decreased in some zones.
