Virus-free technology of potato
Potatoes are nutritious and resistant to storage. It has a short growth period and great potential to increase production, so it is fond of eating for people. However, potatoes are easy to be infected with a variety of viruses, resulting in smaller tubers, deformities, seed potato degradation and so on. The experimental results show that the detoxification of potato by stem tip tissue culture combined with virus detection and the production of virus-free seed potato can effectively prevent the degradation of seed potato and greatly increase the yield of potato. The main detoxification methods are as follows: 1. Take materials and disinfect the tubers of the varieties to be detoxified to sprout. When the buds grow 4~5cm, cut the buds and peel off the outer leaves.
