A planta da sumaumeira (Ceiba pentandra), pertencente à família Bombacaceae, é mundialmente conhecida por suas múltiplas utilidades e qualidade da madeira. No entanto, essa cultura pode ser atacada, na fase de viveiro, por fitopatógenos que prejudicam o desenvolvimento e a qualidade das mudas. Objetivou-se avaliar o efeito da luminosidade e de diferentes meios de cultura no crescimento micelial in vitro de Colletotrichum sp., patógeno isolado de folhas de mudas de sumaumeira . Foram testados os meios de cultura BDA, Extrato de Malte e V8, em placas de Petri, no centro das quais foram colocados discos de micélio do patógeno, sendo mantidas à temperatura de 25±2 ºC, sob os regimes de luminosidade claro contínuo, escuro contínuo e alternado (12 horas claro/ 12 horas escuro). O delineamento experimental foi inteiramente casualizado, em esquema fatorial 3x3, com cinco repetições. Foi avaliado o diâmetro das colônias e calculado o Índice de Velocidade de Crescimento Micelial (IVCM) do patógeno. O maior IVCM do patógeno foi observado no meio V8, sob regime claro contínuo, quando comparados aos demais tratamentos, sendo estas condições as mais indicadas para futuros estudos que envolvam o cultivo de Colletortrichum sp. |

Physiological disorders are among the most important causes of mango postharvest loss. Therefore, the objectives of this study were to identify at harvest and after storage fruit physical and chemical traits related to the incidence of internal physiological disorders in ?Keitt? mangoes. A total of 200 Keitt mangoes were harvested at the commercial maturity. After the harvest, one half of each fruit without the seed was cut longitudinally and evaluated, while the other half containing the seed was treated with sodium hypochlorite at 1000 ?l L-1, covered with a polyvinyl chloride (PVC) film and stored at 10°C until the flesh firmness reached <15 N, which was considered ready-to-eat maturity. According to the results, the physiological disorders incidence after storage reached 9% for jelly seed, 9% for black flesh and 11% for spongy tissue. There were no differences between fruit with and without disorders for AA, SS, TA, and DM analyzed at harvest and after storage. Mangos that developed spongy tissue had at harvest higher skin hue angle, lower levels of calcium (Ca), magnesium (Mg), zinc (Zn), copper (Cu), iron (Fe) and Ca/B ratio, as well as higher levels of manganese (Mn) and N/Ca, K/Mg, K/Ca ratios, compared to sound fruit. Mangoes that developed jelly seed symptoms had at harvest lower levels of total extractable polyphenols (TEP), total antioxidant capacity (TAC), Ca, Mg, Zn, as well as higher Mn levels and N/Ca, Ca/Mg, K/Mg, K/Ca ratios, compared to sound fruit. Flesh nutrient concentrations remained the same in each fruit from harvest to the end of storage. After storage, mangos with jelly seed symptoms showed higher skin hue angle and TEP levels, as well as lower TAC, compared to healthy fruit. Mangos that developed black flesh symptoms had higher levels of N, Mn and N/Ca, K/Mg, K/Ca ratios, as well as lower Ca, Mg, Zn, Cu, Fe and Ca/B ratios at harvest, compared to sound mangoes. After storage, mangoes with black flesh symptoms had darker skin (lower L) and lower skin C and b values, as well as higher TEP levels, compared to sound fruit. In conclusion, the skin hue angle and TEP levels in flesh tissue have the potential to predict at harvest and determined after storage the incidence of spongy tissue and jelly seed in ?Keitt? mangoes, respectively. Skin L, C and b values have the potential to non-destructively determine the presence of black flesh in ready-to-eat ?Keitt? mangoes. Mangoes that developed black flesh, jelly seed and spongy tissue during storage had at harvest low levels of Ca, Mg, and Zn, as well as high Mn levels, compared to healthy fruit. More studies are required to determine the level of each physicochemical and nutritional trait that can be used as an index to predict at harvest or identify ready-to-eat fruit with physiological disorders.
