dc.description.abstract | This study was conducted to investigate physiological responses and mortality of P. koraiensis seedlings under warming and drought treatments. In May 2016, 90 P. koraiensis seedlings (aged 2 years) were planted in each plot (n = 20), and exposed to a combination of + 3 degrees C warming and - 30% drought, with 5 replicates. Net photosynthetic rate (A), stomatal conductance (g(s)), transpiration (E), and maximal photochemical efficiency of photosystem II (F-v/F-m) were measured from April 2017 to December 2018. Seedling mortality was measured eight times during the study period at irregular intervals. A, g(s), and E decreased by - 21.99%, - 34.58%, and - 33.6% under the warming treatment, and by - 5.82%, - 11.03%, and - 8.56% under the drought treatment, respectively, in response to decreasing soil water content and increasing soil and leaf temperature. There was no significant difference in the overall F-v/F-m by the warming and drought treatments. The long-term reduction in photosynthesis by the warming treatment might cause carbon starvation, resulting in a 7.43-fold increase in seedling mortality. Moreover, under the drought treatment, seedling mortality was unaffected since its effects on A were occasional and small as compared to the warming treatment. Due to the unusually high temperature in summer of 2018, leaf temperature was 38.28 degrees C and seedlings were exposed to temperature above 45 degrees C for 10.7 h under the warming treatment. F-v/F-m in August 2018 decreased sharply by - 11.79% and seedling mortality increased by 15.31-fold during summer, under the warming treatment. Thus, leaf damage by severe heat stress may have triggered a rapid increase in seedling mortality. | - |
