“…Growing ginseng in greenhouses on account of incidence inhibition by rainproof cultivation and improving cultivation efficiency have become an affordable alternative solution to this comprehensive problem [8] . The data for cultivating ginseng in the greenhouses, however, are scarce, and little is known about the optimum LTR in shaded greenhouses because the majority of previous studies on the growth of ginseng have been based on analyses undertaken in slanted shading where the LTR is subject to changes in solar altitude.…”

BackgroundGinseng is a semishade perennial plant cultivated in sloping, sun-shaded areas in Korea. Recently, owing to air-environmental stress and various fungal diseases, greenhouse cultivation has been suggested as an alternative. However, the optimal light transmission rate (LTR) in the greenhouse has not been established.MethodsThe effect of LTR on photosynthesis rate, growth, and ginsenoside content of ginseng was examined by growing ginseng at the greenhouse under 6%, 9%, 13%, and 17% of LTR.ResultsThe light-saturated net photosynthesis rate (Asat) and stomatal conductance (gs) of ginseng increased until the LTR reached 17% in the early stage of growth, whereas they dropped sharply owing to excessive leaf chlorosis at 17% LTR during the hottest summer period in August. Overall, 6–17% of LTR had no effect on the aerial part of plant length or diameter, whereas 17% and 13% of LRT induced the largest leaf area and the highest root weight, respectively. The total ginsenoside content of the ginseng leaves increased as the LTR increased, and the overall content of protopanaxatriol line ginsenosides was higher than that of protopanaxadiol line ginsenosides. The ginsenoside content of the ginseng roots also increased as the LTR increased, and the total ginsenoside content of ginseng grown at 17% LTR increased by 49.7% and 68.3% more than the ginseng grown at 6% LTR in August and final harvest, respectively.ConclusionThese results indicate that 13–17% of LTR should be recommended for greenhouse cultivation of ginseng.

Background and objective: The objective of this study was to produce Asiatic hybrid lily with more than two flowers in one year starting from bulbils. This study was to force 'Beni no Mai' bulbils influenced by harvesting date, flower bud removal, and temperature manipulation and to evaluate dormancy and maturity by nuclear magnetic resonance imaging (NMRI) and carbohydrates analysis.Methods: In experiment 1, bulbils were harvested at 0-30 days after anthesis (DAA), and were divided into 7 stages. And, soluble monosaccharides and monosaccharide constituents of bulbils were analyzed. In experiment 2, flower buds of plants that flowered on 21 April were not removed or removed on 1, 13, and 25 April. Bulbils harvested were divided into four groups and planted after cold treatment. In experiment 3, bulbils received a sequential temperature (SEQ CD) treatments for three weeks at 2.5, 5.0, and 7.5°C, 1 week at 10, 12.5, and 15°C, and 3 weeks at 2.5, 5.0, and 7.5°C. In experiment 4, bulbils were harvested 0-70 DAA, and were subjected to spin-spin lattice relaxation time by NMRI.Results: The bulbils harvested at 30 DAA produced two flowers within 282 days, and were better in growth. The bulbils harvested at 30 DAA showed higher concentration of soluble glucose and lower concentration of non-cellulosic neutral glucose. Growth of bulbils removed flower buds before flowering were better than those of bulbils that flower bud was removed at anthesis and 13 Apr. However, the number of flowers of bulbils harvested from plants removed flower buds on 1 Apr. were less than 2. The SEQ CD treatment of 7.5°C/3W-15°C/1W-5°C/3W in bulbils could produce the plants with 2.2 flowers within 300 days after planting. When bulbils were harvested at 0-28 DAA, yellow color corresponding to T2 relaxation time of 15-20 ms was dominant, and bulbils harvested at 56-70 DAA showed T2 relaxation time of 35-50 ms and 50-100 ms.Conclusion: Considering the results of soluble carbohydrate content and T2 relaxation time of bulbils, it was found that the bulbils had a shallower dormancy and were more mature at 30-42 DAA than before 28 DAA. Also, when these bulbils were planted after SEQ CD treatment at 7.5°C/3W-15°C/1W-5°C/3W, plants with two or more flowers could be produced within one year.

: This study was performed to investigate the effects of sowing density and number of seeds sown on the emergence rate and growth characters of Panax ginseng C. A. Meyer under direct sowing cultivation in a blue plastic greenhouse. Ginseng seedlings, derived from seeds sown directly at different densities (90, 108, 135, and 162 seeds per 1.62 ㎡), were cultivated in sandy loam soil within a blue plastic greenhouse. In contrast to the emergence rate, which decreased with an increase of sowing density, number of survival plant showed an increasing trend. Interestingly, the emergence and number of survival plant were significantly enhanced when 2 or 3 seeds were sown per hole compared with when one seed was sown per hole. Growth of the aerial parts of ginseng were not markedly influenced by sowing density or the number of seeds sown. However, chlorophyll content (SPAD values) increased with an increase in sowing density. Root parameters, such as root length, diameter, and weight, and the number of lateral roots decreased with an increase in sowing density, but were not noticeably influenced by the number of seeds sown. Total saponin content was the highest in the treatment plot containing 135 seeds. Similarly, the content of each ginsenoside was also tended to be higher in this treatment than in other treatment plots. On the basis of the results obtained in this study, it was possible to determine the optimal sowing density and seed number for the direct sowing cultivation of ginseng in blue plastic greenhouse.
