本研究提出一种快速提取番茄、茄子、黄瓜DNA的新方法,旨在解决常规蔬菜进行杂种纯度检测时提取DNA特别耗时费力这一难点。实验结果表明,用该方法提取DNA,操作简单、快速、高效、耗费低,不使用高毒试剂,对操作者身体危害很小。同时,电泳检测结果也表明,该方法获得的DNA的质量完全能满足PCR反应的需求,用该种方法获得的DNA可以用于主要果菜类蔬菜杂种纯度检测工作,并且以此可以大大提高主要果菜类蔬菜种子杂种纯度检测工作的效率。 This study proposed a new method for rapid extraction of DNA from tomato, eggplant and cucumber, aiming to solve the difficulty of extracting DNA during the hybrid purity testing of conventional vegetables. The experimental results show that using this method to extract DNA, the operation is simple, fast, efficient, low cost, do not use high-toxic reagents, the harm to the operator is very small. At the same time, electrophoresis test results also showed that the quality of the DNA obtained by the method can fully meet the needs of the PCR reaction, and the DNA obtained by the method can be used for the detection of hybrid purity of the main fruits and vegetables, and can greatly improve the quality of the main fruits and vegetables The efficiency of testing the hybrid purity of vegetable seeds.
