Effect of Shading Level on Growth and Morphological Characteristics of Ligularia fischeri Seedling

Abstract

This study was carried out to survey the early growth characteristics of Ligularia fischeri, plants of halfshaded grounds, primarily used as functional wild edible greens and examine its shading treatment to transplant seedling. The shading treatment was regulated with the shading level(full sunlight, 35%, 50%, 75%, and 95% of full sunlight). According to the experiment, the height was the highest under 75% of shading (17.3 cm), and root diameter was the highest under full sunlight (2.13 mm). It was found that fresh weight (leaf, shoot, root and whole) was the highest (1.784 g, 1.330 g, 0.791 g, 3.905 g respectively ) under 50% of shading. In case of dry weight, leaf, shoot and whole dry weight were surveyed the highest under 35% of shading, and root dry weight was the highest under full sunlight. It was found that S/R ratio and moisture contents (leaf, shoot, root and whole) were the highest under 95% of shading. Leaf area was the highest under 50% of shading (39.3 cm 2 ) and the higher shading level, the higher SLA and LAR. It was surveyed that the higher shading level, the thinner leaf thickness. In case of root characteristics, it was showed that the relatively high height growth under 35%~75% of shading, excepting 95% of shading. As a result of surveying the whole experiment, it is concluded that the early growth of L. fischeri is more effective in producing it under 50% of shading.

“…In Korea, this plant has been used as a wild edible herbal plant and is mainly distributed in damp shady regions of high altitudes more than at least 600 m in the eastern part of Korea Shang et al 2010;Song et al 2014). In addition, the leaves of this species have been used in Korea for medicinal purposes such as treatment of jaundice, scarlet fever, rheumatoid arthritis and hepatic function failure, owing to their antioxidant compounds, like Korean ginseng (Jeong et al 1998;Lee et al 2002Lee et al , 2015Bae et al 2009).…”

Nevertheless, large cultivation of L. fischeri in farm field is difficult, due to the limitation of cultivatable regions (Song et al 2014). In this study, we characterized the complete chloroplast genome sequence of L. fischeri to contribute to further physiological, molecular and phylogenetical studies of this plant.…”
