"A virus infection caused by hibiscus chlorotic ringspot virus. Symptoms induced by HCRSV in naturally infected Hibiscus rosa-sinensis differ considerably; they vary depending on the tolerance of the cultivar and environmental conditions, although duration of infection, and possibly, virulence of the virus isolate also might affect symptom severity (Waterworth et al., 1976; Waterworth, 1980; Raju, 1985). In some cultivars HCRSV induces chlorotic spots in leaves, but in most it induces leaf mottling and/or chlorotic rings. Some cultivars develop no conspicuous symptoms, especially at high average ambient temperatures such as those in summer in Florida (Raju, 1985). Flowers remain symptomless.
Leaves of infected Abelmoschus manihot plants are usually chlorotic, and the chlorosis is more conspicuous when HCRSV occurs in complex with other viruses (AA Brunt and RS Phillips, Horticulture Research International, Wellesbourne, UK, personal communication, 1993).". The disease is Experimental Factor Ontology id EFO_0000782 (Hibiscus chlorotic ringspot virus infection).
