摘要：

A wide range in susceptibility to tomato spotted wilt virus was apparent in 36 cultivars of florist's chrysanthemum (Dendranthema grandiflora) inoculated mechanically or by thrips (Franklinella occidentalis). Significant positive correlations were observed between inoculation by either method and the incidence of infection, and between the incidence of symptoms and the incidence of infection. The incidence of infection in mechanically-inoculated plants was higher at cool (21/16-degrees-C, day/night) than at warm (24/18-degrees-C, day/night) growth room temperatures. The virus was more widely distributed in tissues of susceptible cultivars than in tissues of resistant cultivars and was most readily detected in symptomatic leaves and stems. Latent infections occurred in all cultivars and ranged from 0 to 100%. Latent infections were detected most easily in roots.
