以小麦种子为试材,研究筛选种子胚乳糊粉层中α-淀粉酶调控机制变异体的方法。应用这种方法,在花培纯系内籽粒间未发现变异;在体细胞无性系的籽粒间发现了对激素敏感性改变的变异体。表明了该筛选方法的可行性。 本文还对适宜的试验条件和筛选指标作了探讨。
Wheat seeds were used as experimental materials to study the method of screening α-amylase regulatory variants in seed aleurone layer. Using this method, no variation was found among the kernels of the flower-pure line; variants with altered hormone sensitivity were found between the kernels of somaclonal lines. The feasibility of this screening method is demonstrated. This article also discusses the appropriate test conditions and screening indicators.
