摘    要:以鲁花14为材料,对花生种子发育过程中荚果和种子的发育情况以及花生种子脂肪酸的累积过程进行了研究。结果表明,在果针入土的第39天,小种子(远离果针一端)的平均长度超过大种子(靠近果针一端),在接近成熟时,小种子的平均质量超过大种子。在花生种子中,可以检测到12种脂肪酸。按含量由高到低依次为油酸、亚油酸、棕榈酸、硬脂酸、山萮酸、花生酸、二十四烷酸、花生烯酸、异油酸、亚麻酸、棕榈油酸、豆蔻酸。在花生种子发育过程中,脂肪酸含量随种子的发育逐渐增加,油酸含量不断增多,而亚油酸则呈缓慢减少的趋势。在接近成熟时,油酸和亚油酸占全部脂肪酸含量的79.4%。油酸亚油酸的比值随着种子的发育呈逐渐增大的变化规律。

关 键 词:花生  种子发育  脂肪酸  相对含量

Abstract:The development of the pods and seeds and the accumulation pattern of fatty acids during the development of peanut seeds were studied with Luhua14.Results showed that thirty-nine days after the gynophore into soil,the small seeds away from the fruit needle was longer than the big seeds near the gynophore.Near maturity,the average weight of the small seeds exceeded that of the big seeds.There were twelve different fatty acids in peanut seeds:oleic acid,linoleic acid,cetylic acid,stearic acid,docosanoic acid,arachic acid,tetroacosanic acid,arachnidoic acid,vaccenic acid,linolenic acid,palmitoleic acid,myristic acid.Along with the development of the seeds,the content of total fatty acids and oleic acid increased gradually,whereas linoleic acid decreasd slowly.Oleic acid and linoleic acid accounted for 79.4% near maturity.The ratio of oleic acid and linoleic acid was increasing along with the maturaty of peanut seeds.
Keywords:Peanut  Seed development  Fatty acid  Relative content
