“…SWC at 40 cm is significantly negatively related to SRI, which is clearly different from Jiang et al [66], as they found the SRI of Platycladus orientalis (L.) Franco was significantly positively related to SWC. We consider that the result may be caused by the soil conditions.…”

“…In recent years, there have been many researchers focused on the relationship between SRI and environmental factors [20,29,30,46,61,66]; however, these previous studies did not take into account the effects of many environmental factors together on SRI. Duchesne and Houle [73] built a model with data from three growing seasons that included SR, RH, T, and P that explained 84% of the variance in day-to-day stem diameter variations from June to September.…”

Picea crassifolia Komarov (Qinghai spruce) is an endemic tree species in China and is widespread in the Qilian Mountains, in northwestern China. High temporal resolution changes of Qinghai spruce tree stem growth remain poorly investigated and the relationships between the species growth and climate are still not completely understood. In this study, we assessed the daily and seasonal stem radial variations, and analyzed the relationships between stem radial increment of Qinghai spruce and environmental factors during the main growing period (June-August). We have found that the stem radial variations of Qinghai spruce can be divided into three phases according to the air temperature and that Qinghai spruce has two diurnal cycle patterns. The main growing period of Qinghai spruce is 30 May-31 August according to micro-core measurements, in conformity with the daily mean air temperature keeping above 5 • C. Precipitation and relative humidity have positive effects on the growth of Qinghai spruce, and we develop a multiple linear regression model that can explain 63% of the stem radial increment over the main growing period.

“…Radial growth of tree could be impaired by heat-induced drought stress , Jiang et al 2015. Droughts have been caused not only by low precipitation but also by high temperature because high temperature leads to increased evapotranspiration and reduced available soil moisture (Liang et al 2006).…”

Key message The radial growth of Larix sibirica has exhibited divergent responses to temperatures in the growing season due to the temperature-driven drought stress in the eastern Tianshan Mountains of Northwest China. Abstract The warming of the continental interior of the Northern Hemisphere in the latter half of the twentieth century has led to divergent responses between trees growth and climate factors at high latitudes. This study explored the variability in the responses of radial growth to climate factors and the temporal stability of growth-climate relationships under climate change for Siberia larch (Larix sibirica Ledeb.) in the mid-latitude area of the eastern Tianshan Mountains. The results indicated as follows: (1) Analysis of the relationships between tree-ring width chronology and climate factors before and after the abrupt increases in temperature demonstrated that divergent responses of radial growth occurred in the eastern Tianshan Mountains, suggesting that correlation coefficients with temperature varied significantly in the growing season.(2) Examination of variations in the climate factors limiting radial growth in the two time periods demonstrated that the minimum temperature played a key role from 1989 to 2012. (3) Assessment of the temporal stability of growth-climate relationships by a moving correlation function demonstrated that the positive sensitivity of Siberia larch to temperature during the growing season decreased. The reasons for this 'divergence problem' were the increased drought stress and changes in the physiological responses of trees. (4) Simulation of the trend of basal area increment by linear regression showed that the growth rate of Siberia larch first increased and then decreased. The future effects of increasing temperature may cause significant alterations in forest ecosystems, with greater effects on forests in arid and semi-arid areas.

On a diurnal basis, although the stem radius maintained the diurnal pattern of daytime contraction and nighttime swelling in this stage, this daily fluctuation was mainly controlled by the variation of stem internal water content caused by meteorological factors because of the lowered daily radius increment.…”

Abstract:Fine-resolution studies on the stem radius variation at short timescale can provide useful information about the tree growth process and the major environmental variables that trigger and drive stem radius variation. This study investigated the stem radius variation of Larix principis-rupprechtii Mayr growing in the semi-humid Liupan Mountains of Northwest China at daily and seasonal scales using high-resolution automatic band dendrometers from May to October in 2015. The results showed that the stem radius variation of Larix principis-rupprechtii has a clear diurnal pattern which can be divided into contraction, recovery, and increment phases; and also a seasonal pattern which can be divided into three stages: (1) the rapid growth stage in spring (stage 1) with the radius increment of 94.0% of the total in the entire growing period; (2) the persistent shrinkage stage in the dry summer (stage 2) with a negative diurnal radius increment for most days, and a significantly larger amplitude of stem contraction and recovery than other stages; (3) the minimal growth stage in autumn (stage 3), mainly caused by the lowering temperature and leaf area. The amplitude of stem contraction was significantly correlated with air temperature (both the mean and highest value) in all three stages: vapor pressure deficit (VPD) in stage 1; relative humidity (RH), VPD and soil moisture (M s ) in stage 2; and soil temperature (T s ) in stage 3. This indicates that the stem radius contraction was mainly controlled by the factors influencing tree transpiration rate in spring and autumn stages, but jointly controlled by the factors influencing both the tree transpiration rate and the soil moisture availability in the dry summer stage. The factors controlling the stem radius recovery was similar to the stem contraction. The amplitude of stem increment was significantly correlated with the rainfall amount and air temperature (both the mean and highest value) in stage 1 and 3, M s in stage 2, and the lowest air temperature and T s in stage 3. This indicates that temperature and precipitation were the key factors controlling the stem radius increment in the spring and autumn stages, and soil moisture was the main factor limiting the stem radius increment in the dry summer stage at the study site with semi-humid climate in Northwest China.
