Abstract


Background: High temperature damage in ginseng is influenced by shading materials related not only to temperature, but also to light intensity and light quality. To address, this green-colored khaki shading sheet is widely used. As they are recently, developed, there is limited research information about their attributes and use.

Methods and Results: The four-layered shading net (FLSN), blue-colored shading sheet (BCSS), aluminum-coated shading board (ACSB), and green-colored shading sheet (GCSS) were installed in the wooden A type of sun-block facilities. Two layered black, shading net was additionally used to cover the facilities since the beginning of June. The average temperature at the facility where different shades were tested was in the order of BCSS (28.9℃) > FLSN (27.7℃) > GCSS (27.6℃) > ACSB (27.1℃). However, high temperature injury rates were in order: FLSN > ACSB > GCSS > BCSS. Root weight vaired and was in the order: ACSB > GCSS > BCSS > FLSN.

Conclusions: High temperature damage is possible not only because of temperature increase, but also due to various environmental light factors. Ginseng high temperature injury was minimal when BCSS or GCSS were used by difference of light quality. Although the root weight was higher in ACSB, it could be vulnerable to high temperature damage. Therefore, we propose using GCSS for ginseng shading.
