Abstract: To study the growth, yield and quality improvement of Rehmannia glutinosa virus-free seedlings in the field, we periodically measured the morphology index, physiological characters, photosynthesis index, yield and quality of virus-free seedlings and common seedlings. The virus-free plants were superior to common plants in all growth character indexes. The root yield and quality have been greatly improved. Yield increased by more than 77.35% and catalpol content by 32.90%.
