“…This result was consistent with that of Balandier et al [27] and Lusk [48]. However, Sinz et al [18] found that Fraxinus pennsylvanica regeneration maintains a xed morphology relative to size through seedling and sapling development. In this paper, P/NP of Q. acutissima seedlings decreased as tree size increased, which was in good agreement with the results reported by Balandier et al [27] and Gaucher et al [25].…”

“…Kunstler et al [31]considered that strong morphological adaptation was an important reason for long-term survival of Fagus sylvatica seedlings under forest. However, Sinz et al [18] suggested the establishment and persistence of Fraxinus pennsylvanica seedlings beneath closed canopies showed no signi cant relationships with their morphological adaptation. Soto et al [32] thought light and nitrogen interact to in uence regeneration in old-growth Nothofagus-dominated forests in south-central Chile.…”

“…Su cient seedling bank is the foundation to the success of natural forest regeneration [16,17,18,19]. The structure and composition of natural tree regeneration is closely related to stand density [17], canopy opening [15,20], seedling adaptability of tree species [16,18,19,21] and forest management [14].…”

Background: Natural regeneration is critically important for the sustainable management of artificial forests. Studies have been investigated for the effects of seedlings height distribution and ontogenetic adaptability in a 60-year-old Quercus acutissima artificial pure forest in Mount Tai. Results: The results showed that the height distribution of seedlings under the forest was pyramidal-shape from the year 2010 to 2017. In 2017, the density of seedlings under the forest was only 61.63% of that in 2010, and the number of individuals at each height class was lower than that in 2010, especially the individuals at 20-40cm height class only 32% of that in 2010. With the increase of seedling height under the forest, seedling biomass (SB), ground diameter (GD), root mass ratio (RMR), total root length (TRL), root volume (RV), root average diameter (RAD) and nonstructural carbohydrates (NSC) increased significantly, but leaf mass ratio (LMR), leaf area ratio (LAR), photosynthetic/non-photosynthetic tissue ratio (P/NP), specific root length (SRL) and specific root surface area (SRA) decreased significantly. Correlation analysis showed that SB was negatively correlated with LMR, LAR, P/NP, SRL and SRA, and positively correlated with RMR, TRL, RV, RAD and NSC. NSC was negatively correlated with LMR, LAR, P/NP, SRL and SRA. Conclusions: Therefore, with the increase of seedlings height, the increased carbon storage was helpful for the seedlings of Q. acutissima to survive under the forest for a long time, but the reduced ability of light interception, photosynthetic tissue ratio, water and nutrient absorption capacity contributed to their low survival ratio under the forest.

“…To test the response of the annual ground diameter growth, each of 3 standard regenerated pines were located and marked for REAG and REBG in each gap, respectively. These pines were (i) approximately the average height and ground diameter of each regeneration category, (ii) single stemmed and free of significant disease or herbivore damage, and (iii) not overtopped by nearby regeneration or herbs 45 , 46 . A cross-section of the stem tissue above the apparent ground diameter was collected from each of the 90 regenerated pines and then dried and polished with sand paper for ring analysis 45 , 47 .…”

Understanding the influence of gaps in promoting canopy recruitment will help to maintain structural stability and achieve continuous forest cover. We established three control plots and experimental plots with three replications each (gap sizes L-I, L-II, L-III, and L-IV) in a Chinese pine (Pinus tabulaeformis Carr.) plantation to test the short-term effects of gap size on the age distribution, density and growth, and annual height and ground diameter growth for regeneration established before (REBG) and after (REAG) gap creation. Age distribution exhibited an approximately normal distribution, with the numbers of REBG and REAG decreasing and increasing, respectively, as the age increased. Although there was no difference in density among gap size classes, regeneration growth positively responded to gap size, with maximum values observed in class L-III. Annual average height growth after (AAH-A) gap creation was significantly greater than that before (AAH-B) gap creation for REBG among gap sizes, suggesting that gaps promote the rapid growth of regeneration. However, the responses of height and ground diameter growth in REBG to gap size were not immediate and exhibited a response delay of 2–4 years. Similarly, for the height and ground diameter growth of REAG, significant differences were first observed within years 2–4 after germination in the same growing season for all gap size classes.

“…where key environmental factors such as air temperature, humidity and associated soil properties (pH, temperature, soil depth) affect plant growth and tree distribution, that change significantly within a limited range (Gong et al 2020, Sundqvist et al 2013). The enough seedling composition is underpinning for the successful regeneration of natural forest (Nagel et al 2010, Sinz et al 2011). In addition, low moisture (Rodríguez-García et al 2010), low temperature (Pardos et al 2007) and drought (Padilla and Pugnaire 2007) are not much favorable for the development of seedlings.…”

This study has attempted to estimate above and below ground biomass along altitudinal gradient and examined the relation between carbon stock and diversity indices. The study area was categorized into three sections based on the elevation interval of 200m ranging from 1300m to 1900m. Vegetation sampling was performed in 33 circular plots, each of 500m2 and was selected based on systematic random sampling. Phyto-sociological parameters and above and below ground biomass and total carbon stock were calculated for each section of the study area. Carbon stock showed negative and insignificant relation with species evenness (r=-0.24, P= 0.17) and positive but insignificant relation with species richness (r=0.17, p=0.34) and Simpson’s index of dominance (r=0.18, P=0.31). However, humped shaped and statistically insignificant (P=0.93) relationship was observed between Shannon diversity index and carbon stock. This research results provide baseline information for the management of Hasantar community forest.
