锂离子束诱发青椒变异的初步研究

The Preliminary Study on the Pepper Variation by the Li-ion Beam

以青椒品种为"宇椒一号"为试材,通过地面模拟装置锂离子束处理青椒干种子,利用不同剂量分析其生物效应,探讨青椒辐射诱变变异机理。结果表明:不同剂量的锂离子对青椒影响效应差异较大,其中种子发芽率、幼苗成苗率、苗期长势以及分子检测变异较大,说明锂辐射可以造成青椒的遗传变异,是改良青椒的一种好方法。

With green pepper varieties ‘Yujiao No.1’ as test materials,through the ground simulation device lithium ion beam processing dry seeds of green pepper,using different doses to analysis its biological effects,radiation mutagenesis variation mechanism of green pepper were discussed.The results showed that different dose of lithium influenced the pepper significantly,which indicted that lithium could induce the variation of pepper.Therefore,lithium radiation was a good method to improve pepper.
