title: Effects of cerium on nitrogen metabolism of peach plantlet in vitro.
abstract: The effect of CeCl3 on the rooting and nitrogen metabolism of the peach plantlet in vitro was studied when the CeCl3 was added to the rooted medium. The results showed that the rooting rate and the fresh weight of roots could be increased and the length of root could be enlarged, and the activities of nitrate reductase, glutamine synthetase, glutamate dehydrogenase in the roots were increased significantly, the transformation of NO(3-) to NH(4+) and protein were promoted, and the nitrogen metabolism was accelerated when the plantlets grew in the optimum rooted medium that contained the concentration 0.3 micromol/L Ce(3+).
