G. Y. aMango stem end rot pathogens - Fruit infection by endophytic colonisation of the inflorescence and pedicel.h[electronic resource] c1992 aThe stem end rot pathogens of mango (Mangifera indica), (Dothiorella dominicana, Dothiorella mangiferae, Lasiodiplodia theobromae (Syn. Diplodia natalensis Phomopsis mangifera, Cytosphaera, mangiferae, Pestalotiopsis sp. and Dothiorella "long"), as well as other fungi (including Alternaria alternata), were found to occur endophytically in the stem tissue of mango trees prior to inflorescence emergence. On samples from trees with a record of low stem end rot levels, colonisation did not extend into the most recently produced flush of stem tissue. At a site with a history of high stem end rot levets, sequential monitoring of inflorescence tissue between flowering and harvest by plating out small (C. 8 mm3) tissue pieces revealed, that at least some of the patho gens - Dothiorella spp., P. mangiferae, Pestalotiopsis sp. and C. mangiferae gradually colonised the inflorescence, reaching the pedicel tissue of young fruit - 8 Wk after flowering. Subsequently, detection frequency of the pathogens in inflorescence tissue declined, possibly because of interference from copper residues (from field sprays) accumulating on tissue samples. The detection frequency of A. alternata also increased as Dothiorella spp. declined, however these changes could not be attributed to antagonistic interactions between the two fungi. aBotryosphaeria aDoença aManga aPhomopsis aPós-Colheita aDothiorella aendophyte1 aMEAD, A.
