We investigated the rooting rate, the number of roots, and the state of growth of loquat(Eriobotrya japonica Lindi) plantlet in medium where La(NO3)3 (0.5–100.O µmol/L) was added 20 d after transplanting. The activity of peroxidase, nitrate reductase, and the fresh weight of roots were determined 44 d after transplanting. The result showed that the optimum concentration of La(NO3)3 (1.0–3.0 µmol/L) in the rooted medium could increase the rate and the fresh weight of rooting, promote the length of root, and increase the activities of peroxidase and nitrate reductase.
