图2 低温胁迫下不同品种花生高油酸和普通油酸种子的发芽指数 CK: 种子在25℃条件下萌发6 d; T: 种子第1~3天在15℃条件下萌发, 第4~6天在25℃条件下萌发; NO: 普通油酸花生; HO: 高油酸花生。经单因素方差分析差异达到显著水平, 标以不同小写字母的柱值表示经单因素方差分析和最小显著差异法(LSD)检验差异达到显著水平(P < 0.05)。

Fig. 2 Germination index of high oleate seeds and normal oleate seeds in different peanut varieties under cold stress CK: control group, germination of seed at 25℃ for six days; T: treatment group, germination of seed at 15℃ for 1-3 days, and then 25℃ for 4-6 days; NO: normal oleate peanut; HO: high oleate peanut. Bars superscripted by different lowercase letters are significantly different at P < 0.05 by one-way ANOVA and least significant difference (LSD) test.
