“…Light intensity is one of the most important light components that significantly affects plant photosynthesis and dictates the ginseng production capacity [8,17,25]. It is widely recognized that the ginseng responses to various light regimes (radiations and intensities) depend on the ginseng ages and cultivars, as well as on environmental factors [14,[26][27][28].…”

“…The responses of PGSs regarding the physiology, morphology, and photosynthesis aspects to the light intensity are still speculative. Also, the light intensity at approximately 30 PPFD has been extensively adopted in practical ginseng productions, while Jang showed that the range of 75-100 PPFD was the most effective method for the growth and photosynthetic ability of ginseng seedlings [17,21]. Therefore, this study investigated the influences of the light intensity (30-280 PPFD) on the growth and photosynthesis of PGSs, concomitantly determining the correlations among the studied parameters, thereby delivering basic guidelines and knowledge for the culture of PGSs under different light intensity environments.…”

“…Also, plants have developed sophisticated mechanisms to react to various light regimes, such as light acclimation, which have rendered plant biochemical and morphological traits adapted for the prevailing light environments [16]. Because ginseng is a shade-loving herb that is readily vulnerable to photoinhibition, photobleaching, and chlorosis, shading installation is required during the cultivation period [8,17,18]. The suitable light intensity, therefore, is of great importance for the growth and production of the health-promoting phytochemicals in ginseng.…”

“…For instance, approximately 500 PPFD (75% shade from full sunlight) is considered as a safe point for growing ginseng according to Miskell's report [20]. Jang showed that the range of 75-100 PPFD is effective for the growth and development of ginseng seedlings, while no more than 30 PPFD is widely adopted for the large-scale commercial culture of PGSs in Korea [17,21]. Nonetheless, how different light intensities supplied by PFALs affect the growth, morphology, and photosynthetic ability of PGSs needs to be determined.…”

Compared to the traditional production of ginseng roots, Panax ginseng sprouts (PGSs) are currently regarded as a substitute due to the relatively short-term culture but still high nutrition. However, the optimal light intensity for the growth ability of PGSs and the characterizations of the responses of PGSs to the light intensity have been largely neglected. This study aimed to determine the influences of the light intensity on the growth, morphogenesis, and photosynthetic responses in PGSs. To this end, two-year-old ginseng rootlets were subjected to one of six light intensities (from 30 to 280 PPFD with 50 PPFD intervals) in a plant factory with artificial lighting (PFAL) via LED light for 10 weeks. On the whole, the recorded parameters of the PGSs showed gradually decreasing trends in response to the increasing light intensities. However, the 80 PPFD-treated PGSs possessed similar or greater root dry weights, leaf areas, carotenoids levels, and photosynthesis (the maximal PSII quantum yield) compared to those in the 30 PPFD regime. Additionally, photoinhibition symptoms as evidenced by chlorosis, necrosis, and stunted growth were observed as the light intensity attained 180 PPFD. Thus, 130 PPFD could be considered a safe point for the appearance of photoinhibition in PGSs. Taken together, we show that the light intensity range of 30–80 PPFD is suitable for maximizing the production of PGSs in PFALs.

Ginseng ( Panax ginseng ) has been used as a valuable medicinal plant in Asia, and the demand for ginseng production for health functional food is increasing worldwide after the COVID-19 crisis. Although a number of cultivars have been developed to increase ginseng production, none of them were widely cultivated in Korea because they could not resist various environmental stresses while being grown in one place for at least 4 years. To address this, Sunhong was developed as a ginseng cultivar with high yield and multiple stress tolerance by pure line selection. Sunhong showed high yield and heat tolerance comparable to Yunpoong, a representative high-yielding cultivar, and exhibited 1.4 times lower prevalence of rusty roots than Yunpoong, suggesting that Sunhong can keep its high yield and quality during long-term cultivation. In addition, distinct color and lodging resistance were expected to increase the convenience of cultivation. To supply pure seeds to farmers, we also established a reliable high-throughput authentication system for Sunhong and seven ginseng cultivars through genotyping-by-sequencing (GBS) analysis. The GBS approach enabled to identify a sufficient number of informative SNPs in ginseng, a heterozygous and polyploid species. These results contribute to the improvement of yield, quality, and homogeneity, and therefore promote the ginseng industry.
