Characteristics of Korean pine (Pinus koraiensis) radial growth at different heights and its response to climate change on Changbai Mountain

Abstract

Understanding the relationship between climate and growth at different heights gives insight into the mechanisms by which trees respond to climate change. In this paper, tree鄄ring data at different heights (0.3, 1.3, 4, 10, 15, 20, and 25 m,) on the north side of Korean pine (Pinus koraiensis) trees on Changbai Mountain were collected from 155 cores, taken from 25 Korean pine trees. Dendrochronology and a multiple comparison method (LSD) were used to analyze the radial growth characteristic and the climate鄄growth relationship. The results show that the trends in annual radial growth of Korean pine at different heights were essentially identical. Apart from an abnormal increase in the annual radial growth at a height of 20 m around 1980, the annual radial growths at other heights showed a downward trend. The most obvious variations were found at the base (0.3 m and 1.3 m) and crown (20 m) of Korean pines. With increasing tree height, the annual growth rates at different heights were all reduced. The maximum growth rate was observed at a height of 0.3 m, which

Early Summer Temperature Variation Recorded by Earlywood Width in the Northern Boundary of Pinus taiwanensis Hayata in Central China and Its Linkages to the Indian and Pacific Oceans

“…In addition to the traditional tree-ring studies in the Tibet Plateau and the northwestern arid area in China [ 7 ], tree-ring research in the eastern humid area in China has consecutively developed rapidly. For example, the studies include the response of tree-ring radial growth to climate change [ 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 ], and the reconstruction of climate factors [ 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 ] was from the Greater Khingan Mountain, Mt. Changbai, Mt.…”

Directional Variability in Response of Pinus koraiensis Radial Growth to Climate Change

“…Few researchers have examined intra-individual growth variability. Recently, several studies considering the response of radial growth to climate variables found evidence of height effects [18][19][20][21] and some studies document the growing evidence of direction-specific radial growth for several shrub species [22][23][24]. Fang et al (2015) [25] examined directional growth of trees (Pinus tabuliformis and Picea purpurea) near summits and cliffs within the semi-arid Chinese Loess Plateau, finding that tree cores taken from the south showed greater sensitivity to drought.…”
