ABSTRACT: In this study, we assessed the effect of intercrop planting of Maçã and Prata Zulu banana cultivars in the reduction of black Sigatoka severity and in the productivity of the Maçã cultivar. The treatments used were a combination of 5, 10, 15, 20 and 25% of plants of the Maçã cultivar distributed in plots with 95, 90, 85, 80 and 75% of plants of the Prata Zulu cultivar. Four months after planting, 20 leaves infected with black Sigatoka were distributed at each plot of 200 plants as a source of inoculum. The plots were separated by strips of secondary forest approximately 20 m wide and 15 m high. Each plot was divided in four subplots. Severity evaluation was performed in leaf number 10 during the flowering period. The number of viable leaves and the weight of production (bunches, hands and fruits) were also assessed. The statistical analyses did not show differences between the treatments used. Intercrop planting was not effective in reducing the severity of black Sigatoka in the Maçã cultivar and the yield was similar to that observed in monocultures. RESUMO: Avaliou-se o efeito do plantio intercalado da cultivar Maçã com a cultivar Prata Zulu na redução da severidade da doença sigatoka-negra e na produção da cultivar Maçã. Os tratamentos consistiram do plantio de 5, 10, 15, 20 e 25% de plantas da cultivar Maçã, distribuídas dentro de talhões com 95, 90, 85, 80 e 75% de plantas da cultivar Prata Zulu, respectivamente, perfazendo um total de 200 plantas por talhão. Quando as plantas atingiram quatro meses de idade, em cada talhão foram distribuídas 20 folhas com sigatoka-negra, como fonte de inóculo. Os talhões foram separados por uma faixa de floresta secundária com cerca de 20 m de largura e 15 m de altura. Cada talhão foi dividido em quatro parcelas. No florescimento, registraram-se, na cultivar Maçã, a severidade da sigatoka-negra na folha número 10 e o número de folhas viáveis, registrando-se também, na colheita, o peso dos cachos, das pencas e dos frutos. As análises indicam que todos os tratamentos foram iguais entre si. O plantio intercalado não reduziu a severidade da doença e a produção foi semelhante às registradas em monoculturas com a cultivar Maçã.

Apple chlorotic leaf spot virus(ACLSV) infects temperate rosaceous fruit trees worldwide and causes a wide range of diseases that are economically highly damaging. This study was carried out to analyze genetic variability of regional ACLSV isolates and compare it with ACLSV isolates from other parts of the world. Nineteen amplicons of ACLSV, corresponding to the coat protein (CP) gene of isolates from apple, plum, and nectarine, from two states in southern Brazil, have been analyzed for genetic variation and compared phylogenetically among themselves and with other sequences available in GenBank. Sequences identities among complete CP genes of these isolates ranged from 87.5 to 100% and 92.2 to 100% at the nucleotide (nt) and the deduced amino acid (daa) levels, respectively. In the comparison with isolates from Asia, Europe and North America, identities were 68.4 to 100% and 72.5 to 100% at nt and daa levels, respectively. Phylogenetic trees based on nucleotide sequences showed that these isolates grouped into two clusters, cluster 1 containing apple isolates and cluster 2 comprising apple, plum and nec- tarine isolates. Most Brazilian isolates showed conserved signatures (Ser 40 ,Leu 59 ,Tyr 75 ,Thr 130 and Leu 184 )intheirCPs, which place them with type B6 isolates. However, some Brazilian isolates were found to be variants of type B6. These analyzes indicated that Brazilian isolates had lower genetic variability compared to isolates from China, India and Japan and that the CP genes were under negative selection. The greatest diversity of nucleotides was observed in the central portion of the CP gene, represented predominantly by synonymous substitutions. One natural recombinant was detected among ACLSV isolates from Brazil. Keywords ACLSV . Molecular characterization. Variability. Phylogeny. Recombination. Selection.
