“…The duration of the phenophases found in the three plots in Tulumayo (Figure 3) was similar to that determined in morichels in their natural state in Colombia (Nuñez and Carreño, 2013) although it was possible to identify variations in the times of year when each reproductive cycle occurs, such as what happened in Brazil where flowering began in August (Rosa et al , 2013), while in plantations in Peru, it occurred in February with peaks in April (Gonzales Coral and Torres Reyna, 2010). Although the male flowering period coincided with the female flowering period, the female flowers persisted longer, to increase the chances of pollination (Mendes et al , 2017).…”

Purpose This paper aims to characterize the sexual maturation of M. flexuosa plantations in Tulumayo. Design/methodology/approach The methodology in this paper was selection of three plots in open field and usage of different densities of planting, after the maturation of the first plants, we began the quarterly evaluation. There was total 28 evaluations in seven years of age. Findings As a result, it was determined that at 12 years, the plots with lower density presented a greater number of mature individuals, with a predominance of female palms that produced an average of four bunches of fruit per year, and males five inflorescences. In addition, 15% of adult female plants went dormant, whereas males accounted for 3.4%. Reproductive cycles began in September and culminated in October of the following year, which were synchronized with rainfall. Originality/value Planting density was a determining factor in the early maturity of M. flexuosa and sustainable plantation management.

“…para compreensão em relação ao desenvolvimento dos frutos em função da localização geográfica e do quantitativo de polinizadores com objetivo de estabelecer estratégias para aumentar a produtividade. Foi avaliado de forma experimental, o sistema reprodutivo e os visitantes florais presentes no processo de polinização de flores de Buritizeiro em ambiente de restinga costeira no nordeste do Brasil (Mendes et al, 2017). Foi proposto também trabalho para determinação do valor ambiental da palmeira Buriti de acordo com a disposição máxima a ser pago para conservação da espécie, no sentido de preservação da floresta à medida que se confronta os valores envolvidos nas atividades extrativistas com os valores pagos para conservação do meio ambiente (Vieira, 2016).…”

Espécies de palmeiras (Arecaceae) são fontes de matérias-primas renováveis para atender às demandas das indústrias de alimentos, das farmacêuticas, de biocombustíveis, de cosméticos e outras. O presente trabalho teve como objetivo identificar a produção de conhecimento científico e tecnológico com o uso das palmeiras Mauritia flexuosa Lin. Fil. (buriti), Acrocomia aculeata (Jacq.) Lodd. ex Mart. (macaúba) e Syagrus oleracea (Mart.) Becc. (guariroba), que são utilizadas para desenvolvimento de produtos em diferentes áreas. Foram realizadas pesquisas exploratórias no banco de dados da Web of Science e a proteção de tecnologias em bancos de dados de patentes do Instituto Nacional de Propriedade Industrial (INPI), Escritório Europeu de Patentes (ESPACENET) e Escritório Latino--Americano de Patentes (LATIPAT). Os resultados permitiram identificar 223 publicações de artigos com buriti e 33 depósitos de patentes, para a macaúba, foram identificadas 192 publicações e 20 depósitos de patentes, e para a guariroba, 20 publicações de artigos e dois depósitos de patentes. Foi observado que empresas internacionais sobressaíram em inovação com o buriti, pois realizaram nove do total de 11 depósitos na área de cosmetologia. O Brasil destaca-se como o maior gerador de conhecimento científico relacionado às Arecaceae, com publicações voltadas para as áreas da agricultura, botânica e ciências dos alimentos. Entretanto, os resultados demonstraram que os depósitos de patentes realizados por brasileiros de empresas privadas, instituições científicas e tecnológicas e inventores independentes foram pequenos. O distanciamento entre a produção de conhecimento e o desenvolvimento de produtos indica que o Brasil é incipiente em ofertar inovações para o mercado com a utilização de matérias-primas das palmeiras estudadas.

“…Although the arthropod fauna and the ecological role of individual flower‐visiting species have thoroughly been studied for several palm species (e.g., Ceroxylon sp. ; Carreño‐Barrera et al (2020); Kirejtshuk & Couturier, 2009, and Mauritia flexuosa ; Mendes et al (2017), our knowledge of the insect communities interacting with most dioecious palm flowers, and their fluctuations in abundance and composition during the flowering remains fragmentary.…”

Fine‐scale temporal dynamics of flower visitors sheds light on insect‐assemblage overlap between sexes in a dioecious Ecuadorian palm

et al. 2022

Dioecious plants generally display sexual dimorphism in male and female floral traits, potentially attracting slightly different pollinator communities. The sharing of common floral visitors between male and female flowers and their timing of visits to both sexes is of critical importance to ensure plant's reproductive success. Palm inflorescences are visited by abundant and diverse insect communities, yet the temporal patterns of insect visits on both sexes remain poorly known. We characterized the composition of a community of flower‐visiting arthropods associated with the dioecious ivory palm (Phytelephas aequatorialis, Spruce) in a pre‐montane forest of Ecuador. We monitored the temporal variations in insect visits along the flowering of 12 inflorescences (eight female and four male) using interception traps recovered every 4 h. We report 59 morphospecies in the arthropod community, dominated by three beetle families: Staphylinidae, Nitidulidae, and Curculionidae. Male inflorescences were more abundantly visited than female, but visitors of the later were taxonomically more diverse. Among the 16 pollinator candidates identified, nine visited both inflorescence sexes synchronously at dusk /night whereas the others did so asynchronously during the day. Our study provides new insights into the pollination mechanism of P. aequatorialis. We found evidence of differential pollinator attraction between floral sexes, which may be explained by the sexual dimorphism of both flowers. Synchronicity in dusk/night visits of both inflorescence sexes suggests a sexual synchronization of the signal used to attract pollinators. Abstract in Spainsh is available with online material
