Background The prevalence of understory removal and anthropogenic nitrogen(N) deposition has significantly altered the ecological processes of forest ecosystems at both regional and global scales. However, it remains a pressing challenge to understand how N deposition and understory removal affect leaf nutrient dynamics, nutrient resorption, litter decomposition, and their linkages for better managing forest ecosystems under nutrient imbalances induced by N enrichment. To address this research gap, a field manipulation experiment was carried out in a subtropical Cunninghamia lanceolata plantation with four treatments including: control(CK), canopy N addition(CN), understory removal(UR), and canopy N addition plus understory removal(CN × UR). Green and senesced leaf N and phosphorus(P) concentrations, N and P resorption efficiencies, litter decomposition, and their correlations were *** The results revealed that the average N concentrations of green early and late leaves in UR were increased by 6.61 and 18.89% compared to CK. UR had the highest whereas CN had the lowest P concentrations in green leaves across the two sampling seasons. Following this, UR, leaf type, season, and their interactions significantly affected leaf N, P, and N:P(P < 0.05). The highest leaf N resorption(32.68%) and P resorption efficiencies(63.96%) were recorded in UR. Litter decomposition was significantly retarded in UR(P < 0.01) relative to CN. The regression analysis demonstrated that leaf nutrient status was significantly interconnected with leaf nutrient resorption efficiencies. In addition, leaf nutrient dynamics were strongly correlated with litter nutrients, indicating that both were *** These findings can deepen our knowledge of biogeochemical cycling and reveal contrasting nutrientacquisition strategies on N and P limitation in response to UR and CN. Considering the P limitation, it is important to note that P was resorbed more efficiently, illustrating a

开采深部煤炭时,煤层与顶底板相互作用更加明显,影响工作面安全生产。针对此问题,基于离散元方法,采用PFC2D建立了煤岩组合体试样,分析了不同界面倾角下煤岩组合体强度及破坏特征。结果表明,随着煤岩界面倾角的增加,煤岩组合体试样的峰值强度近似线性减小,弹性模量非线性增加,起裂应力和峰值应变规律性较差,AE计数的峰值逐渐降低,且AE事件出现阶段提前,试样破坏形态逐渐由“V”字形向沿界面倾角破坏转变,且裂纹具有更强的贯穿能力。

为探讨不同种源树木对干旱-复水的生理生态响应,该研究以广东与福建种源木荷为对象,通过盆栽控水方式模拟干旱及复水条件,研究两个种源木荷的水力及碳生理特征、脯氨酸(Pro)及超氧化物歧化酶(SOD)对干旱-复水的响应。结果表明:(1)对照情况下,广东种源木荷的茎木质部水势(Ψ_(xylem))、叶片相对含水量(RWC)、光合速率(A_(sat))与气孔导度(G s)均低于福建种源木荷的。(2)两个种源木荷的水力特征、Pro与SOD对干旱-复水的响应呈一致趋势,其中Ψ_(xylem)、RWC与Pro均能较快恢复至对照水平,而茎木质部栓塞程度与SOD未恢复至对照水平。(3)福建种源木荷叶片的A_(sat)对干旱的敏感性较广东种源的高且复水后恢复至对照水平需要更长时间。(4)复水后福建种源木荷非结构性碳水化合物(NSC)的恢复速率高于广东种源木荷。综上认为,福建与广东两个种源木荷均不能通过短期复水(30 d)来修复被栓塞的木质部。尽管广东种源木荷的光合速率能够更快地恢复至对照水平,但其光合速率低于福建种源木荷,并且其NSC的恢复能力较福建种源荷的低。因此,在未来干旱加剧背景下,广东种源木荷的生长及存活可能受到更大威胁。该研究结果有助于了解种源地气候条件对树木抗旱性的影响,为未来森林的经营与管理提供了理论参考。

气候变化将改变降雨格局,从而导致极端干旱事件增多。然而,树木如何协调生理和生化响应来应对干旱-恢复的机制仍不清楚。本研究探讨了干旱-恢复过程中树木生理与生化特征的耦联关系。我们首先将香樟(Cinnamomum camphora)盆栽幼苗种植在水分充足的条件下,然后通过停止浇水以达到干旱处理的目的。当幼苗胁迫至轻度干旱(气孔关闭)和中度干旱(ψxylem=−1.5 MPa)时,分别对其进行复水处理。在干旱及复水4天过程中,我们测定了香樟叶片水势、气体交换、脱落酸以及非结构性碳水化合物的变化规律。我们发现干旱强度在很大程度上决定了香樟的生理与生化响应,并影响其干旱后恢复。轻度干旱导致气孔关闭,并引起叶片脱落酸累积和水势下降,而中度干旱可进一步引起叶片脯氨酸累积和非结构性碳水化合物的变化。干旱强度的增加会导致气体交换恢复滞后,但对水势的恢复无显著影响。另外,干旱与复水过程中水势与气体交换之间的关系存在较大差异:即干旱过程中水势与气体交换存在很强的耦联关系,而这种耦联关系在复水过程中并不存在,其主要原因是由于叶片脱落酸累积,从而延缓了气孔导度的恢复。综上,本研究结果表明,脱落酸可能是导致香樟旱后气孔导度恢复滞后的主要影响因素。此外,干旱强度对树木生理和生化的恢复具有显著影响。

本文通过研究不同干旱梯度下马尾松(Pinus massoniana)的水力特征及解剖特性,以期全面了解马尾松对干旱的适应机制。以17个月苗龄马尾松苗为材料,设置正常浇水(CK)、中度干旱(MD)和重度干旱(HD)3个水平(分别占田间持水量的75%~80%、35%~40%、25%~30%),分析了不同处理对马尾松水势、含水量、木质部栓塞程度(PLC)、管胞直径、木质部和韧皮部面积等的影响。结果显示:在不同干旱程度下,各项指标均有明显的变化。马尾松苗木茎和叶水势在不同干旱程度下变化不同,根对干旱最敏感。苗木会通过改变光合碳同化与蒸腾速率以及干物质量与耗水量的比例,提高水分利用效率。随着干旱程度的加重,木质部栓塞程度也加重,苗木针叶和茎的结构发生明显的变化。干旱胁迫下,苗木通过主动调整内部结构来增加水分运输效率和数量,从而更好地适应干旱;严重干旱下,内部结构变形,水分运输受阻,但叶片会维持较高的韧皮部面积来提供更高的碳运输效率,降低叶片的碳饥饿风险,防止苗木因在水分状况较差的情况下出现碳耗竭而快速死亡。

【目的】加速贵州省花椒栽培良种化进程,改进花椒栽培管理技术,进而提升贵州省花椒产业的效益。【方法】以贵州省本土花椒品种顶坛花椒和引进花椒品种天珠椒为材料,用Li-6400光合测定仪,在自然条件下测定2种花椒不同成熟度叶片(嫩叶、成熟叶、老叶)的净光合速率、气孔导度、蒸腾速率等光合生理指标,在一定的光照辐射强度梯度和CO_(2)浓度梯度条件下测定净光合速率,并绘制光合-光响应曲线和光合-CO_(2)响应曲线。【结果】2种花椒3种成熟度叶片的净光合速率日平均值由大到小依次为天珠椒成熟叶、顶坛花椒成熟叶、天珠椒老叶、顶坛花椒老叶、天珠椒嫩叶、顶坛花椒嫩叶,其中天珠椒成熟叶的净光合速率日变化呈双峰形,有“午休”现象,老叶和嫩叶呈单峰形,无“午休”现象,顶坛花椒与天珠椒相反。2种花椒叶片的气孔导度日变化曲线基本呈现单峰形,不同成熟度叶片的气孔导度由大到小依次为成熟叶、嫩叶、老叶。2种花椒叶片胞间CO_(2)浓度日变化均呈现先缓慢降低、后逐渐增加的“V”字形曲线。2种花椒叶片蒸腾速率日变化与净光合速率曲线基本一致,即天珠椒叶片呈双峰形,有“午休”现象,顶坛花椒呈单峰形,无“午休”现象。【结论】2种花椒的光合特性具有明显差异,其中天珠椒光合日变化曲线和气孔导度曲线均为双峰,且数值高于本土品种顶坛花椒,说明其适应能力和光合同化能力更强,可作为引进品种在贵州省发展。
