Abstract

【Objective】This study aims to elucidate the regulatory mechanisms of different competition relationships on leaf functional traits in Phyllostachys prominens, providing a scientific basis for mixed-forest management and bamboo stand cultivation. 【Methods】We examined three stand types: Ph. prominens-Ph. edulis mixed forest (PM), Ph. prominens-broadleaf-conifer mixed forest (PB), and pure Ph. prominens forest (PP). Leaf morphological traits, pigment content, and non-structural carbohydrates (NSCs) were analyzed under different competitive conditions. Principal component analysis (PCA) and partial least squares structural equation modeling (PLS-SEM) were employed to explore the differential impacts of interspecific and intraspecific competition on the bamboo's growth strategies and adaptive mechanisms.【Results】(1) The PM stand significantly promoted leaf expansion and biomass accumulation in Ph. prominens, resulting in greater leaf length, width, area, dry weight, and specific leaf area compared to the PP and PB stands (P< 0.05), whereas leaf thickness and dry matter content were significantly lower. (2) Chlorophyll a, chlorophyll b, and total chlorophyll (a+b) contents were significantly higher in the PM stand than in the PP and PB stands (P< 0.05), while the PP stand exhibited a significantly higher chlorophyll a/b ratio. (3) NSCs analysis revealed that soluble sugar content and the soluble sugar-to-starch ratio were significantly higher in the PM and PP stands than in the PB stand (P< 0.05). (4) PCA and SEM analyses indicated that different competition relationships influenced bamboo growth characteristics, which in turn regulated leaf morphology and significantly affected pigment synthesis and NSCs accumulation (P< 0.001). Notably, bamboo height was strongly positively correlated with leaf morphological traits, which, in turn, exhibited significant positive effects on pigment content and NSCs accumulation. 【Conclusion】Ph. prominens adapts to competitive environments by modifying its leaf morphology and physiological traits across different forest stands. Ph. prominens employs a resource acquisition strategy to enhance growth, promoting leaf expansion and sugar accumulation when competing with Ph. edulis, while optimizing carbon allocation to improve stress tolerance and resource use efficiency in broadleaf-conifer forests and pure stands.
