摘　　要：用不同浓度的稀土化合物拌种,对玉米种子的萌发和幼苗生理过程进行了研究。结果表明,适当浓度的稀土化合物处理能促进玉米种子的萌发,加速幼苗根、茎、叶的生长,增加叶片的气孔数和根的维管束数,增加幼苗干物质的累积。The effects of different concerntration of rare earth compound on germination of maize seeds and physiological processes of maize seedings were studied.The results showed:when maize seeds were treated by rare earth compound of appropriciate concentration,germination of maize seeds and growing of roots,stems and leaves of maize seedings were improved;the numbers of leaf stomata and root vascular bundles,and the quantitations of dry matter production of roots and shoots increased.
