Ranking of candidate reference genes in order of their expression stability as calculated by NormFinder.

Note: Expression stability and ranking of 10 reference genes as calculated by NormFinder in all samples (A), different ages (B), different tissue types (C), cold-treated (D), heat-treated (E), NaCl-treated (F), PEG-treated (G), ABA-treated (H). Lower average expression stability (M value) indicates more stable expression.注：本数据集展示了通过NormFinder算法（NormFinder）计算得到的10个参考基因在所有样本（A）、不同年龄段（B）、不同组织类型（C）、低温处理（D）、高温处理（E）、氯化钠处理（F）、聚乙二醇（PEG）处理（G）以及脱落酸（ABA）处理（H）中的表达稳定性与排名。平均表达稳定性（M值）越低，表明基因的表达稳定性越强。
