最近几年激光在农业科技和生产中的应用发展很快,引人注目。激光在农作物育种方面已得到应用。与一般辐射育种不同,激光育种有如下特点:第一,除二氧化碳、铷玻璃等少数激光外,一般无明显的半死剂量;第二,激光对辐射损伤有明显的复活作用。用伽玛射线等处理损伤的种子后,经激光照射可以部分复活;第三,成活率高,诱变类型也广,有株型变异、粒型变异、生育期变异和品质变异等。其中最有意义的是后两者,它可能使我们获得早熟、高蛋白新品种。激光育种目前还处于发展初期,有许多问题需要进一步解决。例如,对不同作物最 In recent years, the application of laser in agricultural technology and production has developed rapidly and attracted people’s attention. Laser has been applied in crop breeding. Different from general radiation breeding, laser breeding has the following characteristics: First, in addition to a small number of lasers such as carbon dioxide and rubidium glass, there is generally no obvious half-dead dose; secondly, lasers have obvious resurrection effects on radiation damage. Third, the survival rate is high, the types of mutagenesis are also wide, with plant type variation, grain type variation, growth stage variation and quality variation, etc. The treatment of damaged seeds with gamma rays and the like can be partially resuscitated by laser irradiation. The most significant of these is the latter two, which may give us access to precocious, high-protein new breeds. Laser breeding is still in its infancy, and many problems need to be solved further. For example, most of the different crops
