title: [Effects of sulfur on physiological and biochemical indices and nutrition quality of garlic].
abstract: The study on the effects of sulfur on physiological and biochemical indices and nutrition quality of garlic showed that when soil sulfur content was 8.41 mg kg(-1), the NR and POD activities, photosynthetic pigment content and photosynthetic parameter (Pn, Gs, E) in garlic leaves were higher. The soluble protein content and CAT activity reached maximum when soil sulfur content was 7.92 mg x kg(-1), while the SOD activity was higher when soil sulfur content was 6.45 mg x kg(-1). When soil sulfur content was 8.41 mg x kg(-1), the allicin, soluble sugar and Vc contents in bulb and the allicin, soluble sugar and soluble protein contents in bolt were increased by 33.67%, 23.75%, 68.82%, 40.95%, 3.45% and 7.45%, respectively. Higher content of soil sulfur (9.48 mg x kg(-1)) increased the contents of Vc and free amino acid in bolt and those of free amino acid and soluble protein in bulb by 15.17%, 20.93%, 6.49% and 8.07%, respectively.
