“…This variation in fertilization between the species studied may be related not only to genetic factors, but also to environmental factors such as temperature and photoperiod (Cordeiro et al, 2019). According to Sanzol and Herrero (2001), temperature, flower quality and chemical treatments can affect an effective pollination period in fruit species.…”

Fusariosis and base rot, caused by the fungi Fusarium oxysporum f. sp. passiflorae and F. solani, respectively, seriously damage the cultivation of sour passion fruit in Brazil. This work aims to obtain and evaluate F1 hybrids of Passiflora spp. wild plants resistant to fusariosis and base rot using genotypes of P. edulis (commercial species) and certify interspecific hybridizations using microsatellite markers. Hybridizations were performed using a P. edulis female parent and P. nitida and P. mucronata male parents for crosses aiming fusariosis resistance, and P. nitida, P. cincinnata and P. quadrangularis for hybridizations aiming tolerance to base rot. 35 microsatellite markers were used to confirm hybridization. The washed roots method was used for fusarium resistance tests and inoculation procedure with a mycelium disk fixed on a small wound on the plant stem for base rot. The interspecific hybridizations provided 49 potentially hybrid genotypes. Confirmation of hybridization by microsatellite marker was verified for 57% of the analyzed genotypes. The hybrids 115-1, 115-3, 115-4, 115-5, 115-6, 115-7, 115-9 and 128 are indicated as promising genotypes for a new stage of the breeding program. In the resistance evaluation of 13 F1 hybrids to F. oxysporum f. sp. passiflorae, the genotypes 142 and 143-2 were selected as the most resistant to continue the breeding program.

“…Os híbridos obtidos do cruzamento entre o UFV-M7 e genótipos resistentes ao Fusarium spp. florescem em temperaturas e fotoperíodos mais baixos em relação aos valores exigidos pela espécie, embora valores mais elevados tenham sido observados em fotoperíodo de 11h50 e 13h25 e temperaturas entre 20 e 24 °C(CORDEIRO et al, 2019).…”

“…Finally, we also need to consider the effects of photoperiod on the triggering of floral budding, and how this differs for each plant species (Silva et al, 2011). In June we have the peak of the dry season and the smallest amounts of daily sunlight available, but the opposite is seen in December, when the availability of daylight is the highest of the year (Souza and Funch, 2016;Cordeiro et al, 2019). .…”

wing-loading, which in turn indirectly affected dispersal distance negatively via falling time. The aerodynamic group also indirectly and positively affected dispersal distance via falling time. 4. These results are innovative in indicating that a set of extrinsic and intrinsic seedrelated factors influence directly and indirectly the dispersal potential of Brazilian savanna anemocoric species. The most important factors found were wind speed and falling time, despite the linear and causal relationships between the analyzed factors. These effects are extremely important, because many times we seek explanations for events in an isolated and direct way, but forget that many factors can act together, modifying the fundamental conditions that influence the ecosystem processes.
