Summary
Leaves showing mosaic virus symptoms were collected
for analyses from alfalfa growing areas in the Isparta region. Alfalfa mosaic virus
(AMV) was detected in the plant samples by using mechanical inoculation of test
plants and serological tests. The macro- and microelements were assayed in the
infected plant samples in order to determine the effects of AMV on the nutrient
content of alfalfa. The quantity of P, Fe, Cu, Zn and Mn decreased and N
increased in the infected alfalfa leaves as compared to the healthy plant
samples, while K did not change. The forage containing virus infected alfalfa
could not be harmful for the domestic animals, and the nutritious value is even
improved because of the increased protein contents.
Key words: alfalfa mosaic virus, alfalfa, nutrient contents.
