稀土对甜菜产量及14C同化产物的影响

EFFECT OF RARE EARTH ELEMENTS ON THEYIELD AND ASSIMILATION PRODUCTSOF 14C IN BEET

摘要:

稀土能够促进甜菜根产量和含糖率的提高,其中,以0.05％处理浓度的效果最好,可提高根产量8—15％,增糖0.6度左右。应用¹4CO₂同位素示踪也表明,稀土能提高¹4C同化产物在根及糖的分配和积累。

Abstract:

The rare earth elements Can increase the root yield and sugar content of beet.The optimun concentration of treatment is at 0.05％, and 8-15％ for root yield, 0.6％ of sugar content in beet were increased
The results of rare earth elements to enhance the distribution and the accumulation of assimilation product of 14C in root and sugar of beet were determined By using 14^CO₂, tracer techniques.
