| ABSTRACT The market requirement regarding fruit type varies from region to region and it is necessary to produce cultivars with different patterns of fruit morphology. Therefore, the aim of this study was to select lines with resistance to tomato leafminer and different fruit shapes in order to meet the different market segments. Seventy-six lines and pre-selected populations were used for pest resistance together with four other susceptible controls (TOM-584, TOM-684, NC-123S, and Santa Clara) and two wild accessions (Solanum pennellii ‘LA 716’ and S. habrochaites var. glabratum ‘PI-127826’) considered resistant. The experiment consisted of tests of resistance to the tomato leafminer Tuta absoluta. The selection of lines was efficient, being obtained 33... |

| Apple trees, cultivars Gala and Fuji, were sprayed at full bloom with thidiazuron (TDZ) at the doses of 0, 5, 10, or 20 g (a.i.) ha-1 and fruit were assessed for quality and maturity. In both cultivars, the increase of TDZ dose had detrimental effects on fruit quality, causing a reduction of fruit red surface and an increase of percentage of fruit that was asymmetrical and with calyx-end rot. TDZ caused an increment of calyx-end aperture that might have increased calyx-end rot. TDZ increased density and the length : diameter (L : D) ratio of the fruit. The number of viable seeds was not affected by TDZ. TDZ resulted in a substantial delay of fruit maturity in 'Gala' but not in 'Fuji'. TDZ also reduced soluble solids content (SSC) in 'Gala' and reduced... |
