“…However, in young and middle-aged forests, which are in vigorous growth stages with active physiological metabolism, resin tapping significantly affects their growth as it requires the consumption of substantial organic material (Chen Guangcai et al, 2016;Yang Zhangqi, 2014). Currently, research on the biomass allocation of Pinus massoniana plantations mainly focuses on biomass and productivity allocation characteristics at different growth stages (Ali et al, 2019a), site conditions and plantation productivity( Ding Guijie, 2000)， planting density and biomass (Ali et al, 2019b), mixed planting measures and biomass (You et al, 2018)， thinning measures and productivity (Deng et al, 2020), and fertilization measures and productivity (Wang et al, 2022), However, studies on the impact of resin tapping on biomass allocation and height-diameter allometric growth dynamics of Pinus massoniana are unclear and limited to aboveground parts. Few studies focus on the changes in biomass allocation of roots, stems, and leaves, and there is a lack of comparative studies on the allometric growth processes between aboveground and belowground parts and among different organs.…”

China has long been the world's largest producer of pine resin. Pinus massoniana Lamb. It is a significant afforestation and timber species in southern China, accounting for more than half of the forest stock in southern China， It proliferates, with high resin yield, making it an essential component of forestry operations south of mountainous areas and a pillar industry in forestry. However, studies on the impact of resin tapping on biomass allocation and height-diameter allometric growth dynamics of Pinus massoniana are unclear. This study focused on Pinus massoniana plantations in the South Subtropical Region of Guangxi to explore the effects of resin tapping on biomass allocation patterns and allometric growth relationships. Whole-tree harvesting was used to collect samples, with diameter at breast height, tree height, and ground diameter as essential variables to construct allometric biomass models suitable for Pinus massoniana forests under resin tapping disturbance. We constructed allometric growth models for aboveground and belowground parts and between organs to reveal the best biomass models and predictive variables. The results showed that resin tapping disturbance significantly reduced the biomass of various organs in Pinus massoniana, with reductions in stem, bark, root, aboveground, and total biomass statistically significant (P<0.05). However, the changes in leaf and branch biomass were insignificant (P>0.05), indicating that the impact of resin tapping is selective among different organs. The goodness-of-fit of allometric growth models showed that models for resin-tapped Pinus massoniana had better fit than those for non-resin-tapped trees. In the developed and tested regression models, except for leaf biomass and root biomass models, the remaining models achieved acceptable performance statistics. Models for stem, bark, and aboveground biomass performed best (models 4, 4, and 7). These models have critical applications in forestry management, providing scientific evidence for biomass estimation and management of Pinus massonianaplantations under resin tapping disturbance.

“…The growth of trees, especially young trees, is affected by various environmental factors, including interspecific competition, slope direction, soil moisture content, and nutrient limitation [ 8 – 10 ]. Among these, nutrient availability is one of the most critical factors that influences tree survival, productivity, and yield.…”

“…Among these, nutrient availability is one of the most critical factors that influences tree survival, productivity, and yield. Based on the differences in soil nutrient status, the appropriate nutrient ratios and amounts of additions required are selected to alleviate nutrient limitation [ 8 , 10 , 11 ]. Previous studies on the effects of nutrient treatments on trees have been focused on simulated nitrogen (N) deposition, phosphorous (P) addition, and mixed N and P addition [ 10 – 13 ].…”

Background Wild apple (Malus sieversii) is under second-class national protection in China and one of the lineal ancestors of cultivated apples worldwide. In recent decades, the natural habitation area of wild apple trees has been seriously declining, resulting in a lack of saplings and difficulty in population regeneration. Artificial near-natural breeding is crucial for protecting and restoring wild apple populations, and adding nitrogen (N) and phosphorous (P) is one of the important measures to improve the growth performance of saplings. In this study, field experiments using N (CK, N1, N2, and N3: 0, 10, 20, and 40 g m− 2 yr− 1, respectively), P (CK, P1, P2, and P3: 0, 2, 4, and 8 g m− 2 yr− 1, respectively), N20Px (CK, N2P1, N2P2, and N2P3: N20P2, N20P4 and N20P8 g m− 2 yr− 1, respectively), and NxP4 (CK, N1P2, N2P2, and N3P2: N10P4, N20P4, and N40P4 g m− 2 yr− 1, respectively) treatments (totaling 12 levels, including one CK) were conducted in four consecutive years. The twig traits (including four current-year stem, 10 leaf, and three ratio traits) and comprehensive growth performance of wild apple saplings were analyzed under different nutrient treatments. Results N addition had a significantly positive effect on stem length, basal diameter, leaf area, and leaf dry mass, whereas P addition had a significantly positive effect on stem length and basal diameter only. The combination of N and P (NxP4 and N20Px) treatments evidently promoted stem growth at moderate concentrations; however, the N20Px treatment showed a markedly negative effect at low concentrations and a positive effect at moderate and high concentrations. The ratio traits (leaf intensity, leaf area ratio, and leaf to stem mass ratio) decreased with the increase in nutrient concentration under each treatment. In the plant trait network, basal diameter, stem mass, and twig mass were tightly connected to other traits after nutrient treatments, indicating that stem traits play an important role in twig growth. The membership function revealed that the greatest comprehensive growth performance of saplings was achieved after N addition alone, followed by that under the NxP4 treatment (except for N40P4). Conclusions Consequently, artificial nutrient treatments for four years significantly but differentially altered the growth status of wild apple saplings, and the use of appropriate N fertilizer promoted sapling growth. These results can provide scientific basis for the conservation and management of wild apple populations.
