1. Parthenocarpy induction and reduction of seeds in fruits of 'Nadorcott' mandarin
ABSTRACT Mandarins commercialization at international market requires seedless fruit production in addition to its ideal organoleptic and visual quality. The objective of the work was to evaluate the efficiency of applications of gibberellic acid and of copper sulfate during anthesis in reducing the number of seeds and in the productive behavior of the 'Nado

2. Self-pollination of the orchid Cycnoches haagii from Brazilian Cerrado results in albino phenotype seedlings
Resumo Cycnoches haagii é uma orquídea epífita alvo de muitos coletores, mas nenhuma referência foi encontrada na literatura sobre sua biologia reprodutiva. Assim, o objetivo deste estudo foi obter informações preliminares sobre os tipos de polinização e sua influência na viabilidade das sementes desta orquídea nativa do Cerrado brasileiro, a fim d

3. PROFITABILITY OF ORGANIC YELLOW PASSION FRUIT AS A FUNCTION OF IRRIGATION, PROTECTED CULTIVATION AND POLLINATION
RESUMO A passicultura tem se tornado uma atividade atrativa, em decorrência de seus benefícios sociais e econômicos, principalmente devido ao rápido retorno econômico com receita bem distribuída na maioria dos meses do ano. Sendo assim, objetivou-se avaliar os indicadores técnicos e econômicos no cultivo do maracujazeiro amarelo combinando fatores de

4. Aspects of the reproductive biology of Zingiber spectabile (Zingiberaceae)
ABSTRACT Ginger (Zingiber spectabile) is cultivated worldwide as a floriculture and landscaping species. Studies on the biology and floral morphology of this species are important for its improvement; however, they are scarce. We investigated the reproductive biology and floral morphology of gingers grown in a germplasm bank. Floral development was monitored

5. Inteligência artificial: novas soluções para velhos problemas
ABSTRACT Dysphagia management, from screening procedures to diagnostic methods and therapeutic approaches, is about to change dramatically. This change is prompted not solely by great discoveries in medicine or physiology, but by advances in electronics and data science and close collaboration and cross-pollination between these two disciplines. In this edit

6. Contamination of corn grain for human consumption with transgenic sequences in Paraguay
Abstract Corn is one of the most important economic, social and cultural agricultural products in Paraguay, being the main ingredient of several typical foods. Due to the cross-pollination of this plant, it can be contaminated with transgenic maize pollen found in nearby fields. The general objective of this research was to evaluate the presence of transgeni

7. The dark side of the rain: self-pollination setbacks due to water exposure in Pavonia varians Moric (Malvaceae), a species with rain-dependent flowering
ABSTRACT Plants that occur in arid or semi-arid environments may restrict their flowering to the rainy season to ensure water availability for reproductive functions. However, the exposure of flowers to rainfall can compromise their functionality, such as complex self-pollination mechanisms. We experimentally tested how rainfall exposure affects the sequence

8. Pollen sources used by Frieseomelitta Ihering 1912 (Hymenoptera: Apidae: Meliponini) bees along the course of the Rio Negro, Amazonas, Brazil
ABSTRACT Insect pollination has influenced the evolution and diversification of angiosperms. Consequently, knowing plants used as food sources by bees, the most important pollinator group, is the first step toward understanding how their ecological relationships works. Pollen source information is also highly relevant for bee management and associated fruit

9. Pollination biology of the endangered columnar cactus Cipocereus crassisepalus: a case of close relationship between plant and pollinator
ABSTRACT The family Cactaceae possesses considerable floral diversity and is exclusively zoophilic. Cipocereus crassisepalus is an endangered species of columnar cactus, whose floral characteristics fit the chiropterophily syndrome. This study aimed to assess the correspondence between floral traits and pollinators and whether the pollination system of C. cr

10. Flowering and pollination ecology of Cleistocactus baumannii (Cactaceae) in the Brazilian Chaco: pollinator dependence and floral larceny
ABSTRACT Cleistocactus baumannii is the only ornithophilous cactus species in the Brazilian Chaco. In addition, this species of Cactaceae invests heavily in flowering in the ecoregion. Such characteristics motivated us to evaluate the temporal availability of flowers in the context of its floral visitors. The reproductive system of C. baumannii, the number o

11. Productive potential and castor bean selection of the FCA-PB cultivar progenies
ABSTRACT Castor bean is a very important crop, however, in Brazil it still has relatively low productivity, 0.47 Mg ha-1 as a mean. Besides that the Country has significant castor oil demand and depends on international commerce to complement its production. The solution of these problems goes through the development of genotypes highly productive and adapte
