Conteúdo: | Colletotrichum corchorum readily produces lesions on the leaves of different cultivars of jute (Corchorus capsularis L.) but the percentage of spreading lesions on cv. JRC 412 is significantly higher than on cv.JRC 321. This difference is less apparent when 1% sorbitol or orange juice is added to the inocula. The rate of germ tube growth on glass and leaf surfaces indicates that growth is inhibited on leaf surfaces of all the six cultivars of jute tested, but the greastest inhibition occurs on JRC 321. The germ tubes are markedly shorter over lesions than apparently healthy areas. Inhibition of growth also occurs in the underlying cells even if the cuticle is damaged prior to inoculation.
