The mean (±SD) area (µm2) of embryo sacs in self-fertilized (SF), cross-fertilized (CF), and non-fertilized (NF) ovules at various times.

Different capital letters within the same line represent significant differences at the 5% level as determined by Duncan's multiple range test, while the same letter represents no significant differences. In addition, completely different small letters after capital letters within the same column represent significant differences at the 5% level based on Duncan's multiple range test, while the same small letter represents no significant difference at the 5% level. Abbreviation: DAP, days after pollination; SD, Standard Deviation.

同一行内的不同大写字母代表经邓肯氏新复极差检验（Duncan's multiple range test）确定的5%显著性水平下存在显著差异，相同字母则代表无显著差异。此外，同一列内大写字母后的小写字母若完全不同，则表明基于邓肯氏新复极差检验的5%显著性水平下存在显著差异；小写字母相同则代表5%显著性水平下无显著差异。缩写说明：DAP为授粉后天数（days after pollination）；SD为标准差（Standard Deviation）。
