Sunflower seed oil content depending on the seedling type

The problem of the appearance of abnormal seedlings is often manifested in sunflower seed germination testing. Abnormality is most often caused by a lack of primary root. However, when sown in a field, abnormal seedlings develop into normal yielding plants. The aim of study was to determine whether the seedling type causes a significant decrease in sunflower seeds oil content. The trial was carried out during the two growing seasons, at the Experimental fields of Institute of Field and Vegetable Crops and Zrenjanin Agricultural Advisory Services, according to split-plot model design in three repetitions. A seed lot of hybrid NS-H-111, which had a higher percentage of abnormal seedlings in the preliminary germination test, was selected for the research. Seeds were germinated, and then seedlings were analyzed and separated normal and abnormal. After that, the seedlings were planted into seedling trays first, and when the plants reached the stage of a well-developed first pair of leaves they were planted on the field
