最近,辐射生物技术在作物育种中占有非常重要的地位,因为它能在较大范围内影响作物的新陈代射过程和生产能力的变化。实质上,用电离辐射所引起的变化取决于应用的剂量。萌芽期间,辐射影响子叶和胚芽中蛋白酶活性的改变这一点,已得到证实。在较低剂量下,膜对矿物离子的渗透性降低,而对磷的吸收却提高。在较高剂量下,蛋白质梯度已改变,并观察到不利的影响。电离辐射一个重要作用是它与矿质养分相互作用。为了研究γ-射 Recently, radiation biotechnology has played a very important role in crop breeding because it can affect the crop’s projectile generation and changes in production capacity to a large extent. In essence, the changes caused by ionizing radiation depend on the dose applied. The fact that radiation affects the change of protease activity in cotyledons and germs during germination has been demonstrated. At lower doses, membrane permeability to mineral ions decreases while phosphorus uptake increases. At higher doses, the protein gradient has changed and an adverse effect is observed. An important role of ionizing radiation is that it interacts with mineral nutrients. In order to study γ-ray
