Application of geometric morphometrics in the field of Botany

This paper systematically reviewed the recent research progress of geometric morphometrics (GM) in botany, and summarized its application fields and research trends. At the technical level, GM, centered on landmarks and semi-landmarks combined with Procrustes analysis and multivariate statistics, achieves standardized description and reproducible comparison of plant morphology. At the application level, GM is widely used in plant classification and identification (e.g., distinguishing closely related Quercus species, identifying Photinia hybrids, discriminating Castanea mollissima cultivars and Cuscuta seeds), morphological modeling and mathematical analysis (e.g., fitting bamboo leaf shapes with the Gielis equation, topological analysis of Sagittaria leaf venation), as well as agricultural, ecological, and genetic research (e.g., assessing tea plant pest damage, analyzing leaf shape plasticity along altitudinal gradients, exploring soil nutrient-morphology correlations, and QTL mapping). At the research trend level, GM is advancing towards multi-omics integration and interdisciplinary applications, demonstrating significant potential in paleobotany, biomechanics, and bionics. This paper indicated that GM, with its high precision, reproducibility, and multi-scale integration capabilities, is propelling plant morphological research from empirical description towards a synergistic “morphology-gene-environment” analysis, providing scientific support for plant taxonomy, ecological adaptation studies, and precision agricultural management.
