It is possible that the luminosity and temperature conditions during the transmission assays, that the biological features of the donor and recipient plants phenological stage of development, nutrition and/or that the characteristics of the buffer used to prepare the inoculum associated with the virus stability and pathogenicity have inhibited or prevented the mechanical and graft transmission of PnMV to wild poinsettias plants.
Tampoco se determinó si los injertos de las variedades "Freedom" y "Red Prestige" transmitieron al PnMV a las plantas de nochebuena silvestre debido a que los injertos abortaron.
