Abstract: Botryosphaeria dothidea is the major pathogen of mango in Brazil, causing stem-end rot, which causes significant losses during transportation and storage. The current strategy to control this particular disease using synthetic fungicides has been ineffective, leaving residues in the fruit. The objective of the research was to study the effect of physical treatments, with hot water rinse brushing (HWRB) and ultraviolet C irradiation (UV-C), individually and in combination, to control stem-end rot of mango. Physicochemical parameters, respiration and resistance induction of the fruit were also analysed. The in vitro trials demonstrated that B. dothidea is a thermoresistant fungus. The individual treatments with HWRB at 65°C for 15 s and 2.5 kJ/m2 of UV-C presented the best results, showing less symptoms of the disease during 18 days of storage. The combination of HWRB with UV-C did not improve the control of the disease when compared to the treatments applied individually. The physicochemical parameters and the consumer acceptance evaluation showed that both physical treatments preserved the appearance of the fruit and delayed the ripening-senescence process. The induction of defence-related enzymes revealed that induced resistance was an important mechanism involved in the control of stem-end rot of mango. |

Brachiaria brizantha and Brachiaria decumbens constitute the two most widely used tropical forage species for cultivated pastures and support both beef and dairy cattle production in the tropics. Two apomictic cultivars ? B. brizantha cv. Marandu and B. decumbens cv. Basilisk ? cover more than 100 million hectares of cultivated pastures throughout Latin America and Southeast Asia. This paper discusses the cytogenetic data of the first successful attempt in obtaining interspecific hybrids between these two species. Artificial hybridization between two diploid (2n = 2x = 18) sexual accessions (B. brizantha, B105 · B. decumbens, D004) was performed in the greenhouse. Only
three hybrids were recovered. One of them was treated with colchicine in tissue culture and two amphidiploid plants were obtained. Meiosis in the diploid genitors was quite normal, while in the diploid hybrid parental genome separation was observed together with some irregular chromosome segregation. Genome separation was also observed in several cells in the two 4n amphidiploid hybrids. In these, a high number of meiocytes with chromosomes chaotically spread in the cytoplasm was recorded during meiosis. The abnormalities observed compromised the meiotic products characterized by polyads. Chromosomes associated generally as bivalents but some association as quadrivalents in diakinesis in one of the amphidiploid hybrids indicates taxonomic proximity between these two species. Moreover, it indicates that introgression of desirable genes may be feasible between these two most important agronomic species of the genus.
