图4 低温胁迫下Quanhua 551种子发芽过程中脂肪酸含量的变化情况 C16:0: 棕榈酸; C18:0: 硬脂酸; C18:1: 油酸; C18:2: 亚油酸; C20:0: 花生酸; C20:1: 花生烯酸; C22:0: 山嵛酸; C24:0: 木蜡酸。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。*表示在0.05水平差异显著。

Fig. 4 Changes of fatty acid contents at seed germination stage of Quanhua 551 under cold stress C16:0: palmitic acid; C18:0: stearic acid; C18:1: oleic acid; C18:2: linoleic acid; C20:0: arachidic acid; C20:1: gadoleic acid; C22:0: behenic acid; C24:0: lignoceric acid. CK: control group, germination of seed at 25℃ for six days; T: treatment group, germination of seed at 15℃ from the 1st to 3rd day, and then 25℃ from 4th to 6th day; NO: normal oleate peanut; HO: high oleate peanut. * means significant difference at the 0.05 probability levels.
