White thread blight is one of the most common diseases affecting several tree species that grow in warm and humid regions. The typical symptoms of this disease include blighted leaves hanging by a white thread of fungal hyphae. Leaf samples exhibiting white thread blight symptoms were collected from neem (Azadirachta indica A. Juss) and Brazilian cherry pitanga (Eugenia uniflora L.) plants in Northeastern Brazil, and from Indian green-tea (Camellia sinensis (L.) O. Kuntze), coffee (Coffea arabica L.), and persimmon (Diospyros kaki L.) in agricultural areas neighboring the Atlantic forest in Southeastern Brazil. Fungal isolates were obtained indirectly from leaf fragments or directly by transferring mycelia and sclerotia to culture medium. Bright field and scanning electron microscopy images revealed the association of Rhizoctonia-like hyphae and basidiospores with the infected leaves. In pathogenicity tests, Rhizoctonia-like fungal isolates induced leaf necrosis on their hosts, and the pathogens were re-isolated from inoculated plants. Phylogenetic analyses based on sequences of the ITS rRNA region indicated the occurrence of Ceratobasidium lineages distinct from previously reported Ceratobasidium species. Our study leads to the description of two new species of Ceratobasidium: the fungal isolates from A. indica, C. sinensis, and E. uniflora were classified as Ceratobasidium niltonsouzanum sp. nov., and those obtained from C. arabica and D. kaki as Ceratobasidium chavesanum sp. nov.

Coffee husk is a residue produced during the fruit processing and it is an excellent source of organic matter. It is an interesting alternative that can be used in the formation of the substrate to plantlet production, but the proportion to be recommended is still unknown. In this context, this experiment was conducted with the objective to study the growth, quality and gas exchange rates of clonal plantlets of Conilon coffee produced using plastic tubes, filled with substrate composed of different proportions of coffee husk to partially replace the commercial substrate. The experiment was conducted in a nursery, following a 3×6 factorial scheme in a completely randomized design; studying three genotypes of Conilon coffee and six proportions of coffee husk in the composition of the substrate for plantlets production from 0% to 100%. Overall, the results showed gains in growth and quality of the plantlets when coffee husk was added in the substrate but decrease in gas exchanges, especially over the net carbon assimilation. Considering the growth and quality, most detrimental effects started being observed with proportions above 38%. Different patterns of response were observed among genotypes, which must be taken into consideration for further researches to help define safety levels and a possible recommendation to use coffee husk in the substrate. |
