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 ：
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 ：
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 ：
To uncover the relationship between fine root traits and soil properties of trees under different fertilization treatments is important for understanding the nutrient acquisition strategies of woody oilseed plants under scientific fertilization management. An experiment of randomized complete block design was conducted in a Sapindus mukoross plantation using combinations of nitrogen (N), phosphorus (P) and potassium (K) fertilizers at different levels (Control: 0 kgha(-2) of N, P and K; level 1: 300 kgha(-2) of N, 250 kgha(-2) of P, and 200 kgha(-2) of K; level 2: 600 kgha(-2) of N, 500 kgha(-2) of P, and 400 kgha(-2) of K; and level 3: 900 kgha(-2) of N, 750 kgha(-2) of P, and 600 kgha(-2) of K). The response of fine root traits and soil properties of Sapindus mukoross to the application of different nitrogen (N), phosphorus (P) and potassium (K) combinations was investigated by measuring fine root traits and soil properties indices. The results showed that: (1) The soil surface is the main location of fine roots. In the 0-20 cm soil layer, the FRB, RLD, FSRL, and RAD of Sapindus mukoross were significantly increased under the fertilization treatment compared with the control. (2) In the 0-20 cm soil layer, the SOC, TN, TP, TK, AP, AK and AN of Sapindus mukoross soils were higher than those of the control group under different fertilization treatments, except for the pH. (3) Correlation analysis showed that FRB and RLD were significantly and positively correlated with SOC, AN and AP, while TP and AP were negatively correlated with FSRL and positively correlated with RAD. RDA showed that AP content in soil was the main factor which influenced the fine root traits of Sapindus mukoross. The results of the study revealed the response strategies of fine root traits and soil properties of Sapindus mukoross to N, P and K fertilizers, provided theoretical support for the scientific cultivation of woody oilseed species, and suggested scientific and rational fertilization and management strategies for Sapindus mukoross plantation forests, a species widely planted in the southern region of China.
