摘要:

通过霍格兰氏完全营养液栽培大蒜研究了不同供硫水平对大蒜营养品质及鲜重的影响。结果显示:硫可显著提高大蒜的品质指标,当营养液硫浓度为2.25 mmol?L-1时,金乡紫皮蒜和金乡白皮蒜鳞茎中大蒜素、可溶性糖、游离氨基酸含量最高,比不施硫处理分别提高48.78%、176.90%、87.80%、44.82%、127.92 %和63.58%,在此浓度下,蒜薹中的大蒜素、维生素C、可溶性糖和游离氨基酸含量也较高。当营养液硫浓度为1.50 mmol?L-1时,两个品种蒜薹可溶性蛋白质含量最高,而鳞茎中蛋白质含量则以高硫浓度(3.75 mmol?L-1)时最高。同时,硫可显著增加大蒜鳞茎和蒜薹的鲜重,至硫浓度为2.25 mmol?L-1时达最大。

Abstract:

Effects of different sulfur content on garlic nutrition quality and fresh weight were studied by Hoagland nutrient solution. The main results are as follows: Sulfur could obviously increase quality indices, when sulfur content was 2.25mmol?L-1, the allicin, soluble sugar, free amino acid contents in bulb of two garlic cultivars were higher, which were increased by 48.78%, 176.90%, 87.80%, 44.82%, 127.92 % and 63.58%, respectively, and the allicin, soluble sugar, vitamin C, free amino acid contents in bolt were higher. When sulfur content was 1.50 mmol?L-1, the soluble protein contents in bolt reached maximum, Higher content of sulfur (3.75 mmol?L-1) increased the contents of soluble protein in bulb. With sulfur content increased, the fresh weight of garlic of the two cultivars was increased, when sulfur treatment content was 2.25mmol?L-1, the fresh weight reached maximum.
