摘要：

Chitosan applied by spraying or inoculation of leaves protected various plant species against local and systemic infection caused by alfalfa mosaic virus (ALMV), tobacco necrosis virus (TNV), tobacco mosaic virus (TMV), peanut stunt virus (PSV), cucumber mosaic virus (CMV) and potato virus X (PVX). The efficiency of chitosan in inhibition of viral infection depends upon the host-virus combination, chitosan concentration and mode of its application. The highest protection was observed in the treated leaves, but the effect also appeared in the non-treated parts of the treated plants. Chitosan added to tobacco protoplasts even 6-8 h after inoculation completely blocked TMV accumulation.
