In similar studies, the leaf length and width of P. insularis, leaf width of P. americana (Kim and You 2010b), shoot height and number of leaves of Panax ginseng (Lee et al 2012), and number of tillers of Cicuta virosa (Park et al 2014b) increased when the environment's CO 2 concentration and temperature increased.…”

“…Therefore, the fruits of S. capitata may be ripened 10 days earlier under global warming condition than control. In the other studies of fruit ripening time, the fruit formation is advanced in Phytolocca insularis (Shin and You 2012), Phytolacca americana (Kim and You 2010b), and Cicuta virosa (Park et al 2014b) when environment CO 2 concentration and temperature increased. The shift of fruit ripening time is thought because of phenological plasticity on environmental change (Haggerty and Galloway 2011).…”

“…In addition, accelerated plant phenology, due to raised annual temperature and precipitation caused by climate change, has been reported (Ministry of Environment 2018). Therefore, several studies on climate change and plant phenological responses have been published in Korea (Kim and You 2010b;Han et al 2012;Lee et al 2012;Shin and You 2012;Choi and Jung 2014;Park et al 2014a;Park et al 2014b).…”

Background: This research aims to study the effect of climate change on the phenology, growth, and physiological traits of Silene capitata Kom., a Korean endangered species II. This study increased CO 2 concentration in a closed glass greenhouse, with the daily mean temperature and CO 2 concentration respectively being 4.61°C and 93.63 ppm higher than the outside temperature (ambient conditions, control). The seeds of S. capitata were sown in control and treatment environments in March 2013 while seedlings were transplanted into individual pots in May 2013. To research phenological changes, the first day of the flowering and ripening of the plants transplanted in 2013 and first day of leafing in 2014 were observed. The growth and physiological responses of mature leaves were also studied in 2013. Results: There was no difference in the first day of flowering, but the first day of ripening was earlier in the treatment group than the control group. There was no difference in the number of rosette leaves between the two groups, but leaf area was wider in the treatment group than the control group. Transpiration rate and stomatal conductance were higher in the treatment group than the control group, chlorophyll content decreased, and photosynthetic rate and water use efficiency were the same for both groups. As a result of simple regression analysis among the transpiration rate, stomatal conductance, photosynthetic rate, and water use efficiency, stomatal conductance increased when transpiration rate increased. Stomatal conductance increased with photosynthetic rate in the control unlike in the treatment group. The photosynthetic rate and water use efficiency increased with transpiration rate in the control group unlike in the treatment group. Furthermore, water use efficiency increased as photosynthetic rate increased in both groups. Conclusion: Due to high CO 2 concentration, the photosynthetic rate was no longer controlled by the stomata, which appeared to suppress the excessive production of photosynthetic products by reducing chlorophyll content. It is believed that the phenological responses of S. capitata under climate change conditions will advance and that stable growth will be difficult in regions lacking moisture due to the high transpiration rate.

Background: In this study, the growth and reproductive response of seedlings, grown in plastic pots with sand, to moisture and nutrients were analyzed in order to study the environmental conditions required to create an alternative habitat for Epilobium hirsutum L., an endangered plant. Results: Vegetative and reproductive growths of Epilobium hirsutum L. are accelerated with increase in moisture and organic matter content in the soil. Among vegetative organs, the number of runners related to asexual reproduction was the highest when the moisture content was over 25% and nutrient content between 7 and 14% in the soil. But the number of flowers related to flowering responses, among reproductive organs, was the highest when the moisture content was maintained at 75% and when nutrient content was 21% in the soil. The number of seeds, related to sexual reproduction, was the highest when the moisture content was over 25% and nutrient content between 14 and 21%. Conclusions: The study results show that a place with high moisture and nutrient content in the soil is advantageous to asexual and sexual reproduction of Epilobium hirsutum L. Therefore, we must serve periodically nutrient and seeds to sustain population in in situ conservation. Furthermore, it is advisable to create in riverside where abundant nutrient content have, making alternative habitat of Epilobium hirsutum L. Also, we must find species that have high contribution degree index through vegetation survey.
