EFFECTS OF DIFFERENT STORAGE PERIOD ON GERMINATION AND SOME QUALITY PROPERTIES OF SAFFLOWER SEEDS (Carthamus tinctorius L.)

摘要

In this study, effects of the storage periods (12, 24, 36, 48 and 60 months) on germination and some quality traits of different safflower (Carthamus tinctorius L.) cultivars (Din?er, Balc?, Yenice and Remzibey), one of the alternative raw materials in the vegetable oil industry, have been investigated. For this purpose, seeds from the 2014, 2015, 2016, 2017 and 2018 growing season were stored at + 4 ° C. In the study germination percentage, days to germination, oil content, protein content, linoleic and oleic acid content were investigated. According to the study result, all characters were found to be significant statistically (P0.05) in terms of storage period. It was determined that as the storage period increased, the germination percentage of safflower seeds decreased and the highest germination percentage was obtained from the 12 months storage period (93.33%). Balc? cultivar has showed the highest oil content (34.54 %) 24 months of storage period. When this study is examined as a whole, it is conclusioned that safflower seeds must be processed in a short time after the harvest; otherwise, there will be losses in germination power and quality of seeds as the storage period increases.
