科学证明:马铃薯品种退化导致产量和品质降低,原因是病毒的侵染。因此,科学家根据植物茎尖一般不易感毒的原理,通过组织培养的方法,获取马铃薯优良种薯脱毒试管苗,并采取一系列严格防毒措施,使感病品种产量和品质得到恢复。实践证明:此种生物技术工程可以解决马铃薯品种因病毒引起的种质退化问题。其主要程序是:选择材料——茎尖剥离——组培试管 Scientific evidence: Degradation of potato varieties leads to reduced yield and quality due to virus infection. Therefore, scientists based on the principle of plant stems are generally not susceptible to poison, through tissue culture methods to obtain potato seedlings of excellent virus-free seedlings and take a series of strict anti-virus measures to make the yield and quality of susceptible varieties restored. Practice has proved that: This biotechnology project can solve the potato varieties due to virus-induced germplasm degradation. The main program is: Select material - stripped tip - tissue culture tube
