Chinese. 采用盆栽试验探讨了土壤硼水平对大蒜生理生化及产量和品质的影响。结果表明，当土壤有效硼浓度为0.85 andmicro;g/g时，大蒜叶片POD、SOD活性、可溶性蛋白质含量、光合色素含量及光合参数均达最高；硝酸还原酶及CAT活性随土壤施硼浓度的提高而增强。同时，当土壤有效硼浓度达0.85 andmicro;g/g时，大蒜鳞茎单重和单薹重分别比对照高23.58%和31.31%。当土壤有效硼浓度达1.29 andmicro;g/g时，大蒜鳞茎中大蒜素、可溶性蛋白质、Vc含量分别提高30.84%、33.28%和232.22%，显著高于对照。而且在此浓度下，蒜薹中游离氨基酸和可溶性蛋白质含量也分别比对照提高20.79%和13.82%。蒜薹中可溶性糖和Vc含量却在土壤硼浓度达0.62 andmicro;g/g时最高。

The results showed that the activity of POD and SOD, soluble protein content, photosynthetic pigment content and photosynthetic parameter in garlic（Allium sativum L.）leaf all reached maximum while boron in soil was 0.85 andmicro;g/g. Meanwhile , the average weight of single bulb and bolt was 23.58% and 31.31% higher than that of CK, respectively.The activity of NR and CAT increased with the increase of concentration of boron in soil. The content of allicin, soluble protein and Vc in bulb increased, respectively, by 30.84%, 33.28%, and 232.22% when boron in soil was 1.29 andmicro;g/g. And on this concentration, the content of free amino acid and soluble protein in bolt improved by 20.79% and 13.82%, respectively. The content of soluble sugar and Vc in bolt were the highest when boron in soil was 0.62 andmicro;g/g.
