tailieunhanh - Species-specific growth and photosynthetic responses of first-year seedlings of four coniferous species to open-field experimental warming
Temperature increase due to climate change may affect the growth and physiological traits of trees. To cope with climate change, it is important to understand the responses of trees to these changes, as well as how these responses vary among species, functional groups, and biomes. | Turkish Journal of Agriculture and Forestry Turk J Agric For (2015) 39: 342-349 © TÜBİTAK doi: Research Article Species-specific growth and photosynthetic responses of first-year seedlings of four coniferous species to open-field experimental warming 1 2 1 1 1 1 3 Saerom HAN , Sun Jeoung LEE , Tae Kyung YOON , Seung Hyun HAN , Jongyeol LEE , Seongjun KIM , Jaehong HWANG , 3 1,4, Min Seok CHO , Yowhan SON * 1 Department of Environmental Science and Ecological Engineering, Korea University, Seoul, Korea 2 Center for Forest and Climate Change, Korea Forest Research Institute, Seoul, Korea 3 Forest Practice Research Center, Korea Forest Research Institute, Pocheon, Korea 4 Department of Biological and Environmental Sciences, Qatar University, Doha, Qatar Received: Accepted: Published Online: Printed: Abstract: Temperature increase due to climate change may affect the growth and physiological traits of trees. To cope with climate change, it is important to understand the responses of trees to these changes, as well as how these responses vary among species, functional groups, and biomes. In this study, we aimed to examine the species-specific growth and photosynthetic responses of firstyear seedlings of 4 coniferous species to future temperature increase by conducting an open-field experimental warming study. The air temperature in the warmed plots was maintained at °C higher than that in the control plots with an open-field experimental warming system. The seeds of Pinus densiflora, Pinus koraiensis, Abies holophylla, and Abies koreana were planted in 2012, and the effects on growth, biomass allocation, leaf area, net photosynthetic rate, and chlorophyll contents of first-year seedlings were measured. Compared to the other species, P. densiflora showed pronounced responses to warming after the growing period, including increase in root collar
