Grafting may succeed in transmitting a virus where other methods fail, thus grafting can be used to differentiate plants infected with virus from plants showing virus-like symptoms due to nutritional deficiencies.阶层 发表于 2025-3-24 09:23:00
Isolation and Diagnosis of Virus Through Indicator Hosts,e is then made by inoculating single local lesion on to hosts that produce either local or systemic symptoms. Pure culture of the virus is inoculated (either mechanically or through vectors) onto a set of diagnostic hosts that are known to produce characteristic symptoms that would help in the identification of the causal virus.看法等 发表于 2025-3-24 10:47:34
