To determine a suitable nutrient solution for rapid propagation of virus-free sweet potato seedlings, four nutrient solutions at two concentrations each were tested using virus-free seedlings of Longshu No.9 in substrate culture to explore the effects of different treatments on the growth of virus-free seedlings. The results showed that both nutrient solution type and electrical conductivity significantly affected morphology and physiology of the virus-free seedling. The Longjiu treatments showed the best growth performance and root vitality, particularly Longjiu 2 resulted in superior stem vine length, stem node number, and aboveground fresh and dry weights compared with other treatments. These results indicated that Longjiu 2 was a suitable nutrient solution for rapid propagation of virus-free Longshu No.9 sweet potato seedlings.
