Abstract

The interplay between leaf and stomata is fundamental for the exchange of carbon and water between plants and the atmosphere. This relationship is pivotal for comprehending the connections between the physical structure and physiological metabolism of plant leaves under various conditions. A study examining the relationship between leaf morphological traits and stomatal traits of the Achnatherum splendens under varying natural soil moisture conditions was conducted along the southern shore of Hulun Lake in Inner Mongolia. In our study, stomatal density (SD) and stomatal relative area (SRA) significantly decreased, while stomatal width (SW), leaf length (LL), leaf area (LA) and leaf dry weight (LDW) increased correspondingly with rising soil moisture. A significant positive correlation between the stomatal traits and leaf morphological traits was observed through principal component analysis (PCA) and permutation test, indicating that the functional traits of leaf morphologies and stomata of A. splendens exhibit a positive relationship. The results reveal the resource utilization strategies of A. splendens in response to varying soil water conditions, offering a scientific data foundation and theoretical support for the management of A. splendens grassland, ecological restoration, and the strategic planning of animal husbandry in Inner Mongolia.

华北半干旱地区不同土壤湿度下芨芨草叶片形态与气孔性状的关系

叶片和气孔之间的相互作用是植物与大气之间碳和水交换的基础。这一关系对于理解植物叶片在不同条件下的物理结构与生理代谢之间的联系至关重要。以内蒙古呼伦湖南岸不同土壤水分条件下的芨芨草（Achnatherum splendens）叶片形态性状与气孔性状的关系为研究对象。随着土壤湿度的升高，气孔密度（SD）和气孔相对面积（SRA）显著降低，气孔宽度（SW）、叶长（LL）、叶面积（LA）和叶干重（LDW）相应增加。通过主成分分析（PCA）和排列检验发现，气孔性状与叶片形态性状之间存在显著正相关，表明芨芨草叶片形态与气孔功能性状之间存在正相关关系。研究结果揭示了芨芨草在不同土壤水分条件下的资源利用策略，为内蒙古芨芨草草地管理、生态恢复和畜牧业战略规划提供了科学数据基础和理论支持。

期刊介绍： Plant Physiology and Biochemistry publishes original theoretical, experimental and technical contributions in the various fields of plant physiology (biochemistry, physiology, structure, genetics, plant-microbe interactions, etc.) at diverse levels of integration (molecular, subcellular, cellular, organ, whole plant, environmental). Opinions expressed in the journal are the sole responsibility of the authors and publication does not imply the editors'' agreement. Manuscripts describing molecular-genetic and/or gene expression data that are not integrated with biochemical analysis and/or actual measurements of plant physiological processes are not suitable for PPB. Also "Omics" studies (transcriptomics, proteomics, metabolomics, etc.) reporting descriptive analysis without an element of functional validation assays, will not be considered. Similarly, applied agronomic or phytochemical studies that generate no new, fundamental insights in plant physiological and/or biochemical processes are not suitable for publication in PPB. Plant Physiology and Biochemistry publishes several types of articles: Reviews, Papers and Short Papers. Articles for Reviews are either invited by the editor or proposed by the authors for the editor''s prior agreement. Reviews should not exceed 40 typewritten pages and Short Papers no more than approximately 8 typewritten pages. The fundamental character of Plant Physiology and Biochemistry remains that of a journal for original results.
