Morphological Characters and Total Phenolic Contents(TPC) of Safflower (Carthamus tinctorius L.) Germplasm

다국어 초록 (Multilingual Abstract)

Safflower (Carthamus tinctorius L.) is known as an oil seed crop originated from southern Asia. Chemical components of safflower have been reported such as phenolic acids, flavonoids, quinochalcones and others. It is vastly utilized in various medical conditions and used for flavoring and coloring purpose. Thus, we examined the amount of total phenolic contents (TPC) and investigated the relation between morphological characters with the TPC in 210 accessions from RDA genebank, Korea. TPC was estimated with Folin-Ciocalteu colorimetric assay. Variations in TPC were evaluated from 21.9 to 147 ㎍ GAE/mg dried extract (DE). Correlation showed there were significant inverse correlations of TPC with leaf width and length while others were not related with TPC. The red color of flower had the lowest range of TPC. The maximum and minimum of TPC was all in the yellow color of flower. Biplot analysis revealed that the positive contributors of Dim1 were leaf width, length, flowering and weight of 100 seeds. Meanwhile, Dim2 was mostly contributed by ripening stage. Accessions K185021 containing high TPC could be used for further research in developing new varieties and functional products.
