N2 - Rapeseed contains high levels of glucosinolates (GSLs), playing pivotal roles in defense against herbivores and pests. As their presence in rapeseed reduces the value of the meal for animal feeding, intensive efforts to reduce them produced low-seed GSL cultivars. However, there is no such variety suitable for the south part of Japan. Here, we tested the effects of cold oxygen plasma (oxygen CP) on seed germination and GSL and lipid content, in 3 rapeseed cultivars. According to the cultivars, oxygen CP slightly stimulated seed germination and modified the GSL levels, and decreased GSL levels in Kizakinonatane but increased those in Nanashikibu. In contrast, it negligibly affected the lipid content and composition in the 3 cultivars. Thus, oxygen CP modulated seed GSL levels without affecting seed viability and lipid content. Future optimization of this technique may help optimize rapeseed GSL content without plant breeding.
