摘　　要：在黑龙江省西部干旱地区,以＂克新13＂马铃薯为材料,利用不同浓度的硼砂浸种处理,进行盆栽试验,通过测定马铃薯幼苗形态建成、物质积累、糖代谢及相关酶活性,研究硼砂对马铃薯幼苗质量的作用效应。结果表明：适宜浓度硼砂（0.5～2.0 mg·L^-1）浸种处理能有效地提高马铃薯株高和茎粗,改善地上部和地下部干物质积累,促进叶片中的糖代谢及相关酶活性,从而提高幼苗质量;当硼砂浓度达到5.0 mg·L^-1,则抑制了马铃薯幼苗的正常生长,从而影响了幼苗质量。In the experiment,seeds of potato（ Kexin No. 13） soaked with different concentration of borax was used in pot culture to study the effect of borax on the potato seedling quality through measuring potato seedling morphogenesis,matter accumulation,sugar metabolism and related enzymatic activity in dry areas of west Heilongjiang field. The results showed that appropriate concentrations of borax（ 0. 5 ～ 2. 0 mg·L^-1） improved seedling quality through effectively increasing the potato plant height and stem diameter,improving aerial and subterranean dry matter accumulation,promoting sugar metabolism and related enzymatic activity of potato leaf. When borax concentration was more than 5. 0 mg·L- 1,the normal growth of potato seedlings was restricted,and quality of potato seedling was affected.
