Effects of Lanthanum and Europium on Rooting of Plantlet Eriobotrya Japonica Lindl. in vitro
The effect of La^3+ and Eu^3+ on the rooting of Eriobotrya japonica Lindl. plantlet in vitro was studied with adding La^3+ and Eu^3+ to the rooted medium. The rooting rate, the number of root and the length of root were studied after transplanting 20 d. The activity of peroxidase, nitrate reductase and fresh weight of roots were determined after transplanting 44 d. The results show that the optimum concentration range of La^3+ ( 1.0 ～ 3.0 μmol· L^-1),Eu^3+ (2.0 ～ 3.0 μmol·L^-1 ) in the rooted medium can increase the rooting rate and the fresh weight of roots, and promote the length of root and raise the activities of peroxidase and nitrate reductase significantly. La^3+ has more effect in improving the rooting rate, root length and the activities of peroxidase and less effect in promoting root fresh weight and the activities of nitrate reductase than Eu^3+.【Effects of Lanthanum and Europium on Rooting of Plantlet Eriobotrya Japonica Lindl. in vitro】完成机构：DepartmentofBiologyScience,CollegeofLifeSciences,SuzhouUniversity,Suzhou215006,China
