“…In recent studies, Bourdon et al (2010) reported endoreduplication occurs in fleshy fruits that developed rapidly in 13 weeks with three to eight cycles of endocyclespecially in Solanaceae Cucurbitaceae. According to Marques et al (2011), the complete maturation of the fruit of pitaya occurs 30 to 40 days after the flower opens. This fast development of the fruits presented a correlation with the phenomena of endoreduplication.…”

“…But recently, itoccupied an increasing importance in exotic fruit market of Europe due to its exotism and organoleptic characteristics. The interest for the plant is recent and required more studies involving the agronomic, genetics and technology (MARQUES et al, 2011;BASTOS et al, 2006).…”

“…O primeiro florescimento ocorreu em novembro, havendo florescimentos sucessivos até meados de abril. Em Lavras -MG, o florescimento da pitaya se dá em três a cinco surtos de floradas (MARQUES et al, 2011), entre novembro a março, enquanto que, em Israel, o florescimento de H. undatus, H. polyrhizus e H. costaricensis (estas duas últimas espécies de polpa roxa) ocorrem em dois ou três fluxos durante o verão (WEISS et al, 1994). NERD et al (2002), também em trabalho realizado em Israel, observaram que o florescimento de H. undatus e H. polyrhizus, nas zonas costeiras, ocorreu no verão e outono, com três ou quatro fluxos, enquanto nas regiões de vale foi restrito ao outono, com um pequeno fluxo (menos que cinco flores por metro linear).…”

“…Na região de Lavras, MG, o florescimento ocorre entre 19 a 21 dias após a emissão das gemas (MARQUES et al, 2011). A abertura floral ocorreu no início da noite, com fechamento na manhã seguinte, sendo que, em dias nublados, ela se estende até quase o fim da manhã.…”

Pollination and reproductive system of synchronopatric species of Cactaceae (Cactoideae) subject to interspecific flow of pollen: an example of ecological adaptation in the Brazilian Chaco

et al. 2017

Three synchronopatric Cactaceae species, Echinopsis rhodotricha, Harrisia balansae and Praecereus saxicola, have mostly nocturnal anthesis and similar flowers, characteristics that motivated us to perform a comparative study of reproductive ecology. Reproductive phenology was sampled monthly from December 2014 to November 2015. We describe floral biology, breeding system via pollination treatments and evaluate floral visitors from focal and filming observations. Pollen grains found on moth proboscis were compared among cactus species under light microscopy. We used fluorescent dye particles to test intra- and interspecific pollen flow. These three species have extended flowering with greater intensity in the wet season, causing high overlap. They have white and hypocrateriformis flowers that open at twilight or nightfall and last about 15 h. H. balansae seems to be self-incompatible, while E. rhodotricha presented self-compatibility. P. saxicola presented self-fertility, but most of the population seems to be self-incompatible. We suggest sphingophily for the three species, but only P. saxicola was visited by Manduca rustica (Sphingidae). However, we observed pollen grains of all three species on the proboscis of moths, especially M. rustica and M. sexta. Prolonged anthesis allowed bees (herein considered as secondary pollinators) to visit flowers of E. rhodotricha and P. saxicola. It can be concluded that the studied species share nocturnal and diurnal pollinators, suggesting interspecific pollen flow, which, however, could not be detected with fluorescent dye particles. In view of the low frequency of primary pollinators, it appears that these three species have different reproductive strategies, ensuring the fruiting and production of viable seeds.
