Drought stress can delay the start of germination, reduce the percentage of germination and reduce seedling emergence, which can later have certain negative effects on plant growth and the final crop yield. In this research, carried out in laboratory conditions, the germination of two alternative oilseeds were analyzed and determined; camellia (Camelina sativa L.) and mustard (Sinapis alba L.) at different levels of osmotic potential to determine the effect of reduced osmotic potential on total seed germination, germination rate index, time to 50% seed germination and germination index. In addition to the above, two alternative oilseeds were examined in relation to rapeseed, which is most often used in agricultural practice. In both alternative oilseeds, better germination parameters were determined in drought conditions than in rapeseed. The highest percentage of germination at a reduced osmotic potential of -0.6 MPa (weak drought intensity) was found in mustard, while at a reduced osmotic potential of -1 MPa and -1.4 MPa (medium and strong drought intensity), it was found in camelina. The previously mentioned alternative oilseeds could serve as a substitute in the production of significant oilseeds, due to better adaptation to drought stress during germination.
