We present investigation of gene expression profiles by means of singular spectrum analysis (SSA). The biological problem under investigation is the decomposition of bicoid protein profiles of Drosoph...
辐照对鲜食核桃发芽率与胚芽内源激素含量的影响（Effect of Irradiation on Budding Inhibition and Endogenous Hormones Content of Embryo of Fresh Walnut）
鲜食核桃 辐照 贮藏 抑芽 内源激素
2010/5/5
为探讨辐照对鲜核桃的抑芽效果及胚芽内源激素与其萌发的关系,以辽河4号鲜核桃为试材,用不同剂量60Coγ射线处理后,研究了常温(20±3)℃下和(0±1)℃冷藏30d后再于（27±1）℃温度下贮藏核桃的发芽率及0、0.1、1.0kGy剂量处理核桃胚芽中内源激素含量的变化规律。结果显示,两种贮藏条件下,对照样品胚芽分别在20d和12d萌发,萌发时内源激素ABA（脱落酸）含量下降,GA3（赤霉素）、IA...
