用不同浓度的稀土（ＲＥ）处理马尾松种子，结果表明，ＲＥ能明显地提高种子活力、发芽率和发芽速度，促进根芽的生长；降低过氧化物酶活性和ＩＡＡ氧化酶活性，提高ＩＡＡ含量；各项指标以３００ｍｇ／Ｌ浓度处理效果最好。
Treatment of Pinus massoniana seed with different concentrations of rare earth (RE) showed that RE could obviously improve seed vigor, germination rate and germination rate, and promote the growth of root buds; reduce peroxidase activity and IAA oxidase activity and increase IAA Content; each index to 300mg / L concentration of the best treatment effect.
