Anticuerpo conjugado, Onion yellow dwarf virus, OYDV para 1000 ensayos, 1 tubo_0.2ml

OYDV (3) is transmitted by several aphid species in the non-persistent manner and by inoculation of sap, mainly to certain Allium species. It is probably distributed world-wide. The virus causes onion yellow dwarf: stunting of first-year onion plants, with the leaves showing irregular yellow striping to almost complete yellowing, downward curling, flattening, crinkling and flaccidity. It also causes deterioration during storage and premature sprouting of onion bulbs. In onion seed plants, the virus causes striping, curling and distortion of flower stems, reduction in the number of flowers and seeds, and impairment of seed quality. In shallot leaf symptoms are similar, but leaf curling and plant stunting is often more severe.
