Anovas.Hyperspectral Analysis of Primed Lettuce Seeds.pdf

ANOVA and MANOVA of Spectral Data of Lettuce Seeds from Two Genotypes Subjected to Priming.ANOVA was used to examine differences in hyperspectral bands based on cultivar and seed treatment (non-primed, wet primed, dry primed, and stored primed). The experiment was established using a randomized complete block design (10 lots) with two factors: the first factor was the cultivar (2 levels), and the second factor was the seed treatment (4 levels).Subsequently, a MANOVA was conducted to evaluate how the treatments influenced the hyperspectral properties of the seeds. Various statistical criteria, such as Pillai's trace, Hotelling-Lawley trace, Wilks' lambda, and Roy's largest root, were used to determine the significance of the treatments considering all response variables (Cheng et al., 2023b; Xu et al., 2022).4o两种基因型生菜种子经引发处理后的光谱数据的方差分析与多元方差分析。本研究采用方差分析（Analysis of Variance, ANOVA），基于品种与种子处理方式（未引发、湿引发、干引发及贮藏引发）探究高光谱（hyperspectral）波段的组间差异。实验采用随机完全区组设计，共设置10个种子批次，包含两个实验因素：其一为品种（2个水平），其二为种子处理方式（4个水平）。随后，开展多元方差分析（Multivariate Analysis of Variance, MANOVA）以评估不同处理方式对种子高光谱特性的影响。研究采用Pillai迹、Hotelling-Lawley迹、Wilksλ及Roy最大根等多种统计准则，结合所有响应变量以检验处理效应的显著性（Cheng等，2023b；Xu等，2022）。4o
