WebIt is used to diagnose a virus by its reactions in a variety of plant species, to test the infectivity of virus samples using local lesion hosts, and to propagate viruses. The virus preparation is rubbed onto the surface of the leaf in such a way as to break the surface cells without causing too much mechanical damage. WebFactors Affecting Infectivity Assays. Infectivity assays have four component factors which must each receive scrupulous consideration: (1) plant host, (2) plant growth medium and the size of pots in which the medium is placed, (3) fungal inoculum, and (4) environmental conditions. Each will be discussed separately here.
