초록

Mulberry exhibits unique characteristics and functionalities across various components, including the roots, branches, leaves, and fruits. However, despite numerous studies on mulberry, research on this plant at the seedling stage is insufficient. Therefore, this study aimed to compare the suitability for seedling cultivation and antioxidant effects of four Korean mulberry cultivars, namely, Daesim, Suhong, Simgang, and Cheongsu. In terms of seed weight, germination rate, and growth rate, Daesim was the most suitable cultivar for seedling production. Polyphenol and flavonoid content analysis showed that all cultivars, except for Cheongsu, showed the highest phenolic content at the 2-week seedling stage. Similarly, antioxidant assays using 2,2'-azino-di-3-ethylbenzthiazoline sulfonic acid (ABTS) and 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radicals revealed that the antioxidant effect of all cultivars, except for Cheongsu, increased with cultivation at 2- 4- and 6-week. However, mulberry seedlings had a slower reaction rate against DPPH radical removal than mulberry leaves. In addition, ABTS radical scavenging activity showed a different correlation with polyphenol content. This phenomenon may be due to the different polyphenol compositions between mulberry leaves and seedlings. The results of this study suggest that mulberry seedlings exhibit different bioactivities from mulberry leaves, and component analysis is required in further research.

Abstract

Mulberry exhibits unique characteristics and functionalities across various components, including the roots, branches, leaves, and fruits. However, despite numerous studies on mulberry, research on this plant at the seedling stage is insufficient. Therefore, this study aimed to compare the suitability for seedling cultivation and antioxidant effects of four Korean mulberry cultivars, namely, Daesim, Suhong, Simgang, and Cheongsu. In terms of seed weight, germination rate, and growth rate, Daesim was the most suitable cultivar for seedling production. Polyphenol and flavonoid content analysis showed that all cultivars, except for Cheongsu, showed the highest phenolic content at the 2-week seedling stage. Similarly, antioxidant assays using 2,2'-azino-di-3-ethylbenzthiazoline sulfonic acid (ABTS) and 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radicals revealed that the antioxidant effect of all cultivars, except for Cheongsu, increased with cultivation at 2- 4- and 6-week. However, mulberry seedlings had a slower reaction rate against DPPH radical removal than mulberry leaves. In addition, ABTS radical scavenging activity showed a different correlation with polyphenol content. This phenomenon may be due to the different polyphenol compositions between mulberry leaves and seedlings. The results of this study suggest that mulberry seedlings exhibit different bioactivities from mulberry leaves, and component analysis is required in further research.
