Experimental Data on the Effects of a Static Magnetic Field on Seed Germination and Early Seedling Growth of Swietenia humilis 2026

This dataset contains the experimental data collected during a study on the effects of a static magnetic field on seed germination and early seedling growth of Swietenia humilis. The data were recorded as part of a controlled experiment in which seeds were continuously exposed to a static magnetic field of 4.3530 mT for 60 days, under three treatments: (1) magnetized metal washer, (2) non-magnetized metal washer, and (3) control without a washer.The dataset includes measurements of germination percentage, germination rate, and lengths of cotyledons, stems, and roots for individual seedlings under each treatment. The data are presented in tabular format with clear variable names and units, facilitating reuse for comparative research, meta‑analyses, or modeling efforts in plant physiology and magnetic field exposure studies.These data support the findings reported in the related research on seedling growth responses under magnetic field exposure and may be particularly useful for researchers in plant biology, forest ecology, conservation biology, and related environmental sciences. The dataset is provided in Excel (.xlsx) format with a README describing the structure of each column and the experimental protocol.
