Abstract
reezing of winter oilseed rape, because of severe winters, in the last few years in Poland, caused increase of interest in spring oilseed rape cultivation. The aim of research was to define the relationship between fertilisation with sulphur and glucosinolate content and pathogenic fungi occurrence on seeds of spring oilseed rape ‘Star’. Sulphur was applied as ionic and elementary in three different doses: 0, 20, 60 kg ××ha-1. The results showed that sulphur fertilisation modified the glucosinolate level. Total alkenyl glucosinolate content depended mainly on the way of sulphur application and its form. The doses of sulphur applied were the main factor influencing on indole glucosinolate content Alternaria brassicae was an only pathogenic fungus frequently occurring on investigated seeds. Sulphur fertilisation resulted partially in decrease of intensity of disease. Negative correlation between indole glucosinalate content in seeds and the occurrence of Alternaria brassicae on them was found.
