Abstract :
Introduction Paris polyphylla var. chinensis (Franch.) Hara (P. polyphylla) is a perennial medicinal plant with a reputation for therapeutic properties. It is imperative to study the photochemical processes of P. polyphylla in order to determine the optimal levels of shading and moisture management for its cultivation in artificial environments.Methods In this study, six shading levels (no shading, 30%, 50%, 70%, 80% and 90% shading) and three soil water contents (20%, 40% and 60% of the soil water saturation capacity) were established to determine the appropriate shade intensity and soil moisture content for the growth of P. polyphylla.Results The results showed that only the low shade groups (no shade and 30% shade) showed irreversible damage to the daily photosynthetic dynamics of the plant over the course of a day. It is important to note that excessive light can damage not only the quantum yield for electron transport (phi Do) and PSII light quantum yield (Fv/Fm), but also various physiological mechanisms that can lead to overall plant damage and a decline in organic matter. A comparison of Fv/Fm during the midday period showed that the optimum shade intensity is between 50% and 70%. Low shading can significantly increase light use efficiency (LUE), but also reduces net photosynthetic rate (Pn) and transpiration (Tr), indicating the negative effect on P. polyphylla growth. Considering the balance between growth rate and damage incidence, 50% shade should be the optimal treatment for P. polyphylla, followed by 30% and 70% shade. It was also observed that treatment with low soil water content (20%) significantly reduced Pn and LUE, while increasing stomatal conductance (gs) and water use efficiency (WUE). This is associated with a decrease in the light response curve, indicating that low soil moisture inhibits the growth of P. polyphylla and increases the likelihood of irreversible light damage, so the optimum soil moisture content for P. polyphylla should be above 20%.Discussion Considering the economic benefits and the growth and health of P. polyphylla in artificial cultivation, it is recommended that shade be controlled at around 50% while maintaining soil moisture between 40% and 60% of water content.

Abstract :
This study investigates how exogenous volatile organic compounds (VOCs) influence the root responses of Cunninghamia lanceolata under nutrient limitations. Specifically, we assessed the differential effects of syringic acid and 1-butene on root morphology, phosphorus acquisition, and stress resilience. Clonal Chinese fir seedlings were utilized to test the effects of treatment with these two exogenous VOCs under both phosphorus supply (1.0 mM KH2PO4) and no phosphorus supply (0 mM KH2PO4) treatments in a controlled pot experiment. Compared to syringic acid, 1-butene significantly enhanced root morphological traits, including root length, specific surface area, and root volume. These morphological changes enhanced the root's ability to acquire phosphorus. Moreover, the addition of 1-butene increased the underground phosphorus use efficiency (PUE) by 25.6% compared to the addition of syringic acid. Furthermore, the addition of 1-butene stimulated higher activity of antioxidant enzymes such as superoxide dismutase (SOD) and peroxidase (POD). Proteomic analysis revealed that 1-butene induced significant changes in root protein expression, particularly in proteins associated with stress responses, phenylpropanoid biosynthesis, and phosphate transport. Compared to syringic acid, 1-butene promoted the differential expression of phosphate transporter proteins, indicating its beneficial effects on the root systems of Chinese firs under low-phosphorus stress. These findings underscore the potential of 1-butene in promoting root efficiency and phosphorus acquisition in forest species, providing insights for enhancing plant adaptation to nutrient limitations.

Abstract :
Improving forest soil quality through effective afforestation and management practices remain a global challenge and understanding the interactions between tree roots and their surrounding soil environment is essential. However, the dynamic relationships between forest tree roots and changing soil conditions are not well understood. This study investigated the adaptive characteristics of Chinese fir (Cunninghamia lanceolata) roots in response to variations in soil water and nutrient availability. We explored roots distribution, architecture, biomass allocation, and associated soil properties in 16-year-old Chinese fir plantations established across different slope positions. Our findings revealed that nutrient-rich surface soil (0-20 cm) varied significantly by slope position, with the upper slope exhibiting lower nutrient content. For example, phosphorus content at the upper slope averaged only 91.30% and 87.50% of that found on the middle and lower slopes, respectively. Additionally, soil moisture content increased as slope position decreased, reaching 15.87-25.86% on the lower slope. Root distribution was most extensive on the middle slope, with horizontal and vertical root spread averaging 2.58 +/- 0.18 m and 1.49 +/- 0.15 m, respectively. Across all slope positions, Chinese fir roots consistently exhibited a fishtail-shaped branching structure. As slope position decreased, soil water and nutrient resources became more abundant, the proportion of root biomass relative to total plant biomass also declined. On the lower slope, root biomass accounted for only 68.89% and 84.56% of the proportion observed on the upper and middle slopes, respectively. These results highlight the importance of understanding root-soil interactions for optimizing root development and plant adaptation. Tailoring water and nutrient management strategies to specific site conditions can enhance Chinese fir root architecture and productivity under varying environmental constraints.

Abstract :
Context Root plasticity is an important physiological mechanism for trees to adapt to nitrogen (N) deficiency and the unequal distribution of ammonium nitrogen (NH4 (+)-N) and nitrate nitrogen (NO3 --N) for promoting growth. However, the response of root plasticity in Cunninghamia lanceolata and Schima superba remains unclear. Methods A pot experiment with C. lanceolata and S. superba compared N deficiency (0.5 mmol L-(1)) and normal N (2.0 mmol L-(1)) under five NH4 (+)-N to NO3--N ratios (10:0, 8:2, 5:5, 2:8, 0:10). Root morphological and physiological traits and seedling growth were investigated. Results Under N deficiency, C. lanceolata showed significantly higher total root surface (TRS) and total root volume (TRV) at higher NO3 --N concentrations, although the roots were shorter and thicker than normal N. It also showed an increased root tissue density (RTD) while specific root length (SRL) and specific root surface area (SRS) decreased. In contrast, roots of S. superba elongated at higher NH4 (+)-N concentrations, with an increase in TRS, TRV, SRL, and SRS, while RTD decreased. Different N supply treatments significantly affected N-metabolism enzyme activities in the roots of both species. The root biomass of C. lanceolata and S. superba increased compared with normal N supply level, and the relatively high NH4 (+)-N concentrations favored aboveground growth in both species. Principal component and correlation analysis revealed that there were differences in the response of C. lanceolata and S. superba to different N supply treatments. Conclusion Appropriately increasing the application of NH4 (+)-N under N-deficient conditions promotes the growth of C. lanceolata and S. superba.

Abstract :
We aimed to clarify the nutrient allocation strategies of Cunninghamia lanceolata (CL) and Schima superba (SS) and their differences in N uptake and utilization under acidic stress and heterogeneous allocation of N. One-year-old seedlings of CL and SS were cultured in sands with three pH levels (pH rate 4.5, 5.5, and 6.5) and five different N form ratios (NH4+-N to NO3--N ratios 10:0, 7:3, 5:5, 3:7, and 0:10) in the greenhouse. The C, N, and P contents and C:N:P stoichiometry in leaves, total biomass, and NH4+-N and NO3--N contents in the cultivation substrate were analyzed after 160 days. At the pH rate of 4.5, the N contents of CL and SS significantly decreased. However, the N contents of SS increased at the pH rate of 5.5. At the pH rate of 5.5, the N content of CL and SS increased under the cultivation substrate, with ratios of 10:0 and 7:3, and 3:7 and 0:10, respectively. The N content of CL was significantly positively correlated with its P content. The C:P ratios of CL and SS were significantly positively correlated with their C:N ratios and N:P ratios. Under the same treatment, the differences in C:N:P stoichiometry were more significant between CL and SS at the pH rate of 5.5. The NH4+-N content of the cultivation substrate in CL and SS was higher than the NO3--N content. At the ratio of 7:3, the C:N stoichiometric ratio of CL and C:N:P stoichiometric ratio of SS were negatively correlated with total biomass. At the pH rate of 5.5, cultivation environments with high NH4+-N and NO3--N amount respectively increased the N content of CL and SS. The CL is susceptible to N limitation, and SS is susceptible to N and P limitation.

Abstract :
【目的】探究栽培基质pH和铵硝态氮配比对亚热带主要针叶树杉木和阔叶树木荷幼苗叶片氮代谢酶活性及植株氮含量的影响。【方法】设置栽培基质为2个pH水平(pH_1=4.5和pH_2=6.5)和3个铵硝态氮配比(NH_4~+-N∶NO_3~--N分别为10∶0、0∶10、5∶5),分析和比较2个树种幼苗叶片的谷氨酰胺合成酶(GS)、谷氨酸合成酶(GOGAT)、硝酸还原酶(NR)和亚硝酸还原酶(NiR)活性及各器官氮含量差异。【结果】(1)与基质pH=6.5相比,pH=4.5抑制了杉木和木荷叶中氮代谢酶GS、GOGAT、NR和NiR的活性,增加了杉木根、茎、叶中的铵态氮含量,降低了杉木各器官中的硝态氮含量和总氮素积累量,降低了0∶10配比下木荷叶的氮素积累量。(2)10∶0配比显著增加杉木叶中的氮代谢酶活性和pH=4.5处理下木荷叶中的氮代谢酶活性、增加pH=6.5处理下木荷根和叶中的铵态氮含量、木荷根的硝态氮含量及杉木茎叶及总的氮素积累量。5∶5配比显著增加pH=4.5处理下木荷根中硝态氮含量。0∶10配比显著增加pH=4.5处理下杉木叶中的铵态氮含量,增加pH=6.5处理下木荷叶的NiR活性,木荷茎叶和总氮积累量。(3)在同一处理下,杉木叶中的氮代谢酶活性均低于木荷,表明木荷具有比杉木更强的同化氮素的能力。(4)相关性分析表明,杉木总氮素积累量与氮代谢酶活性、根的硝态氮含量呈显著正相关,与器官铵态氮含量呈显著负相关,木荷总氮素积累量与叶铵态氮含量呈显著负相关。【结论】栽培基质pH为4.5的栽培环境不利于杉木和木荷幼苗对氮素的吸收,铵态氮添加可促进杉木的氮素积累,而硝态氮添加可促进木荷的氮素积累。故在生产中应综合考虑栽培基质的pH和树种特性等因素选择适宜的铵硝态氮比例进行杉木和木荷幼苗及林地的氮素营养管理。
