摘要
本文分析了我国部分甜菜品种资源的蔗糖、钾、钠、α-氮含量及分布趋势。结果表明蔗糖平均含量为15.56±2.17%,部分材料的含量主要集中在15~18.9%之间,占分析材料的58.5%;钾平均含量为3.68±152meq/100g,多数材料含量集中在2-4meq/100g之间,约占67%;钠平均含量为4.48±2.11meq/100g,含量集中在4-7meq/100g之间的材料占50%;α-氮平均含量为2.4±2.15meq/100g,多数材料的含量低于2meq/100g,约占55%。在三大生态区的甜菜资源材料中,东北生态区材料蔗糖平均含量最高,钾和钠平均含量最低,α-氮平均含量属于中等水平。同时筛选出一批优质材料。
An analysis on the quality of 564 materials of sugarbeet variety resources was conducted in 1987-1990. In the materials, 376 ones came from Northeast China, 93 ones from North China and 95 ones from Northwest China. The content of sucrose' potassium, sodium and α-nitrogen of the materials was analysed. The distribution tendency of the four contents in the materials was described.
