| 摘 要： | 研究了镧、钕、铈3种稀土元素对白桦种子发芽力的影响以及发芽过程中生理生化指标的变化。用氯化镧、氯化钕、氯化铈的饱和溶液浸种8h对种子发芽力有显著效果。同时，用氯化镧浸种8h可明显提高种子内超氧化物歧化酶和过氧化物酶的活性，降低了物质渗出率。其中以体积分数为20％的处理效果最好。

| Abstract: | The effects of lanthanum(La) and heodymium(Nd) and cerium(Ce) on seed germination capacity and the physiological and biochemical indexes were studied. During the germination process,there was significant effects on seed germination when the seeds were soaked in the saturated humidity of La chloride and Nd chloride and Ce chloride for 8 hours. The treatment of 20% has the best effect. |
