摘 要 ：本文研究了稀土元素对甜菜的生物效应。结果表明，稀土元素可显著地提高种子萌发率，促进幼苗生长，增加幼苗根系活力、叶片净光合速率与块根产量，并明显地降低了甜菜叶片细胞膜在低温下的透性，即提高了叶片的抗寒力。

Abstract:The paper deals with the physiological effects of rare-earth elements on sugar beet. The experimental results showed:Rare-earth elements increased the rate of germination and promoted seedling growth. The vigour and weight of root and the net photosynthetic rate of the leave were significantly increased. The permeability of sugar beet cells under low temperature in treated plants were lower than that of the control.
