马铃薯块茎感染了病原,不仅会影响产量和品质,而且也妨碍国际间遗传资源的交流。试管培养技术有利于消灭病害,克服以上缺点。但迄今在这个体系里,还是采用在试管内培养幼小植株体的方法,如能改为在试管内诱发块茎,就能够建立起更加合理的体系。寻求低成本、少费工因而更加合理的试管块茎诱发技 Potato tubers are infected with pathogens that affect not only yield and quality, but also hamper the international exchange of genetic resources. Test tube culture technology is conducive to the elimination of diseases, to overcome the above shortcomings. However, so far, in this system, a method of cultivating young plants in test tubes has been adopted, and a more rational system can be established by inducing tubers in vitro. Seeking low-cost, less labor and therefore more reasonable tube tuber induction
