The influence of the sulphur nutrition conduction upon sulphoxides accumulation in the garlic bulbs was studied. It was found that application of sulphur as ammonium sulphate in quantity up to 75-100 kg S/ha induced proportional increase of sulphoxides in bulbs from 3.03 up to 4.57 mg/g. Subsequent increasing of the sulphur doses applied did not induce any trustworthy changes. When potassium sulphate was used for feeding similar results were obtained. The potassium and nitrogen increase equivalent to the amounts of them applied together with sulphur did not induce any trustworthy changes too. Also it was registered the garlic variety sulphur nutrition specificity, that was closely connected with degree of the floral spear development. So, in the bulbs of non-spear-forming variety (Ukrainian white) the maximal increasing of the sulphoxide content was 78.6% against control whereas for Boguslavsky 10, the variety with most advanced floral spear (with height up to 125 cm), the increasing of sulphoxides was only 43.6%.
研究了硫营养传导对大蒜鳞茎中硫氧化物积累的影响。发现以硫酸铵形式施硫量达75 - 100千克硫/公顷时，鳞茎中硫氧化物比例从3.03毫克/克增至4.57毫克/克。随后增加硫施用量未引起任何显著变化。使用硫酸钾施肥也得到类似结果。与硫一起施用的钾和氮的增加量与其施用量相当，同样未引起任何显著变化。还记录了大蒜品种硫营养特异性，这与花薹发育程度密切相关。因此，在不形成花薹的品种（乌克兰白蒜）的鳞茎中，硫氧化物含量相对于对照的最大增幅为78.6%，而对于花薹最发达（高达125厘米）的品种博古斯拉夫斯基10，硫氧化物的增幅仅为43.6%。
