Beta patellaris, planta-teste para o vírus da necrose branca do fumo

A. S. Costa

SUMMARY

Studies on the host range of the Brazilian tobacco streak virus were made in an attempt to find a host plant that would develop local lesions. Many representatives of Leguminosae, Solanaceae, Compositae, and from other families were tried. Local lesions were not formed in inoculated leaves of the guar plant as in case of American tobacco streak virus, and the lesions developed in leaves of tobacco and Nicotiana rustica plants were not considered satisfactory for counts.
From all plants tested the most satisfactory results were obtained with Beta patellaris. The leaves of this plant developed local lesions two days after inoculation and the lesions could be counted after four days.
