Dataset: Experimental data and R-scripts for statistical and multivariate analyses for tomato plants under cadmium stress treated with melatonin-loaded silica nanoparticles

This dataset contains raw Excel files and R scripts used for statistical and multivariate analyses of studied attributes of tomato plants subjected to cadmium (Cd) stress and treated with melatonin-loaded silica nanoparticles. It includes data for bar, line and box plots, Duncan’s multiple range test (DMRT) results, correlation analyses, principal component analysis (PCA), and heatmap visualizations. The dataset provides a comprehensive resource for reproducing these analysis.

本数据集包含用于对受镉（cadmium, Cd）胁迫并经褪黑素负载型二氧化硅纳米颗粒处理的番茄植株研究性状开展统计与多变量分析的原始Excel文件及R脚本。其涵盖用于绘制柱状图、折线图与箱线图的数据集、邓肯氏多重范围检验（Duncan’s multiple range test, DMRT）结果、相关性分析数据、主成分分析（principal component analysis, PCA）结果，以及热图可视化相关内容。本数据集可为上述各类分析的复现提供全面的支撑资源。
