稀土对甜菜光合产物分配影响的研究
A Study on the Effect of Rare-earth Element on the Distribution of Photosynthate in Sugar-Beet
【摘要】 本文利用同位素(14CO2)示踪法研究了稀土对糖用甜菜块根、糖分增长期光合产物分配的影响。结果表明,稀土能够促进甜菜同化CC2.提高根冠比,改善光合产物的分配,有利于光合产物向块根运输。其队,以0.05%浓度处理的效果为最好。
【Abstract】 The effect of rare-earth elements on the distribution of photosynthate in sugar beet by isotepic(14CO2) tracing method were studied in this paper. The experimental results indicated that rare-earth elements stimulation CO2 assimilation, increase the ratio of root and tops, improve distribution of photosynthate and ctimulate transport of organic matter from leaves to roots. The treatment con-sentration with 0.05% is the most significant among all treatments with earth elements.
