Effect of Soybean Mosaic Virus on Root Volume and Dry Weight of Soybean Plants1
- B. L. Keeling2
The effect of soybean mosaic virus (SMV) on root volume and dry weight of soybean [Glycine max (L.) Merr.] seedlings was determined in two environments (greenhouse and controlled environment chamber). Root volume of susceptible cvs. ‘Bragg’ and ‘Tracy’ was reduced up to 61% 30 days after 10-day-old seedlings were inoculated. The reduction in dry weight of roots and top portion of Bragg and Tracy seedlings ranged from 38 to 59%. Root volume of D73-7725 (resistant) was reduced 18% by SMV when the plants were grown in a controlled environment chamber but was not reduced in the greenhouse environment.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
