| 摘 要： | 以甜菜ST13092、SD13829、25和HI0474为材料,通过盆栽水培研究了不同钠钾比作用下对甜菜幼苗的干物质重、叶面积、总叶绿素含量及光合速率的影响。结果表明,当Na+替代K+50%时,耐盐品种甜菜幼苗的干物质量、叶面积、叶绿素含量和光合速率均有所提高;而耐盐弱品种甜菜幼苗的干物质量、叶面积均有所下降,叶绿素含量和光合速率均有所提高。随着钠钾替代率的增加,所有甜菜幼苗的干物质量、叶面积、叶绿素含量和光合速率均有所下降。研究结果表明:钠钾替代对于耐盐品种的效果要明显优于耐盐弱品种,Na+只能部分替代K+,不能完全替代K+的功能。 |

| Abstract: | Sugarbeet ST13092,SD13829,25 and HI0474 were used to research the effects on dry weight,leaf area,total chlorophyll content and photosynthetic rate of sugarbeet under different rates of potassium and sodium in potted hydroponic culture.The results showed that using Na+ to replace K+ with 50% ratio,the rate of dry weight,leaf area,total chlorophyll content and photosynthetic rate of tolerant salt varieties were totally increased.And the rate of dry weight and leaf area of susceptible salt sugarbeet were reduced when total chlorophyll content and photosynthetic rate were increased.With the increasing substitution ratio of Na for K,the rate of dry weight,leaf area,total chlorophyll content and photosynthetic rate of all the beet seedlings were declined.The result indicated that substitution of Na for K on tolerant salt sugarbeet varieties was more effective than susceptible salt varieties;Na+ can replace K+ partially but not absolutely for beet growth. |
