Abstract:
... The objective of this study was to determine the inheritance of traits related to seed oil yield and fatty acid profile components and to estimate the genetic relationships between these traits in Cucurbita moschata D. This study assessed six generations derived from crosses between parents with contrasting traits under study. F₁ plants were obtained from the crossing between BGH 7319 (P₁) and ‘Tr ...

Abstract:
... Japanese apricot blooms in mid-winter, and thus severe weather conditions, including low temperatures, sometimes limit pollinator activity and consequently decrease fruit set rate and yield. Plant physiology is also affected by weather conditions. In this study, we aimed to evaluate the effect of pollinator activity on fruit set rate and yield, in comparison with the effects of meteorological fact ...
... The flavor of ‘Yali’ pear fruits has substantially declined recently as a result of poor pollination tree selection. Xenia effect is a powerful mechanism for regulating aroma production. To study the effect of different pollens on aroma quality and the molecular basis of xenia effect in ‘Yali’ pear fruits, ‘Hongnanguo’ and ‘Xuehuali’ were used as pollinizers, and the hybrid fruits were named YH an ...
... Persimmon fruits accumulate proanthocyanidins during development. Proanthocyanidins form insoluble complexes with saliva proteins, which promote a sensation of dryness in the mouth called astringency. Persimmon cultivars are classified according to pollination and the presence of astringency at harvest. The different characteristics between persimmon cultivars lead to different metabolic pathways ...

Abstract:
... Pollinator richness, abundance and visitation frequency may be affected by the abundance of floral resources and abiotic factors, influencing plant reproductive success. We analysed whether the diversity, abundance and frequency of butterfly visitation on Lantana camara vary across the year in a tropical urban landscape and whether this variation in butterfly community influences plant’s reproduct ...
bird pollination; cross pollination, etc ; Bombax ceiba; Zosterops; birds; flora; forage; nectar; pollen; China; Show all 10 Subjects
Abstract:
... Filament union is a widely distributed characteristic in angiosperms where the stamens in a flower are united by filaments in diverse modes. Yet, its adaptive significance has remained empirically unexplored. Bombax ceiba (Malvaceae) has large red flowers with two whorls of stamens differing in degrees of filament union, and therefore provides an opportunity to explore the adaptive significance of ...

Abstract:
... Three different forms of cultivated cucumber, viz. Cucumis sativus L. var. sativus (Devraj, Long Spl. and Local), were studied for morphological parameters, reproductive efficiency and reduction divisions in male track. Analysis of these three forms for 17 morphological characters and three pollination experiments (OP = open pollination, HSP = hand self-pollination, HCP = hand cross-pollination) d ...
insect pollination; open pollination, etc ; autogamy; cultivation area; green infrastructure; pollen; pollinators; soybeans; stigma; Argentina; Show all 10 Subjects
Abstract:
... Soybean is the most important crop for Argentina in terms of cultivated area and annually exported tons. Although soybean is autogamous, crop yields can be enhanced by pollinators. The aim of this study is to analyze the effects of insect pollination on soybean production. A pollination exclusion experiment (15 replications) was conducted to analyze the effects on seed production per plant in thre ...
... Bumble bee foragers provide essential pollination services in both natural and agricultural ecosystems. However, foraging is not monolithic; rather, it is a complex behavior encompassing multiple phases that utilize different sensory cues and decision-making processes. Understanding how the interplay of spatial scale and forager experience interact with behavioral state to modulate what sensory in ...
... Pollination services are a frequently overlooked component of urban ecosystems. As cities look to become more sustainable and incorporate more urban green spaces, these pollinator services are coming to the forefront, and educating the public about the habitat and foraging needs of urban pollinators is becoming more important. Increasingly popular features in urban gardens are “bug hotels”, which ...
insect pollination; wind pollination, etc ; climate classification; dioecy; habitats; life history; researchers; seed dispersal; sex ratio; Australia; Show all 10 Subjects
Abstract:
... Dioecious-plant life-history characteristics and reproduction vary greatly among species, and have been linked to certain climate and habitat types, particularly tropical and island habitats. Australia is a large, predominantly arid continent, although it also contains mediterranean, temperate and tropical climates. Dioecious plants occupy each of these climate types, with their respective habitat ...

Biodiversitas 23: 2544-2552. Insects have various roles, one of which is as pollinators. Horticultural crops such as tomatoes and chilies need the help of pollinating insects to increase productivity. The stingless bee, Tetragonu ...

Abstract:
... Prunus avium L. is one of the most important temperate zone fruits in the world. Most of the cherry cultivars always have difficulties of fertilization and fruit set due to self-incompatibility, so they need suitable and compatible pollinizers for commercial fruit production. In this experiment, pollination compatibility of cherry cultivars of ‘Napoleon’, ‘Burlat’, ‘Zhan’, and ‘Lambert’ was studie ...
pollination, etc ; ecological function; pollinators; terminology; Show all 4 Subjects
Abstract:
... Pollination is a key ecological function of most terrestrial ecosystems. Decades of research on single‐trophic‐level communities, particularly plant communities, have helped to build the foundation of diversity–function theory. Yet as it stands, this theory appears to be less useful for intertrophic‐level functions such as pollination, as evidenced by empirical findings that are often inconsistent ...
pollination, etc ; Cretaceous period; extinction; fossils; Show all 4 Subjects
Abstract:
... The present-day ubiquity of angiosperm-insect pollination has led to the hypothesis that these two groups coevolved early in their evolutionary history. However, recent fossil discoveries and fossil-calibrated molecular dating analyses challenge the notion that early diversifications of angiosperms and insects were inextricably linked. In this article, we examine (i) the discrepancies between date ...

self-pollination, etc ; fruits; homozygosity; outcrossing; Show all 4 Subjects
Abstract:
... Self-incompatibility (SI) is a prezygotic mechanism that prevents self-pollination in flowering plants by distinguishing between nonself- and self-pollen. It controls sexual reproduction by promoting outcrossing and avoiding inbreeding. For thousands of years, this trait has been effectively exploited by breeders and growers as a tool to manipulate domesticated crops. However, efforts to spell out ...

... MAIN CONCLUSION: Four heterotic QTL and a heterozygous segment for plant weight were identified by Graded Pool-Seq, QTL-seq and traditional genetic linkage analysis in heading Chinese cabbage. Heading Chinese cabbage (Brassica rapa L. spp. pekinensis) is a cross-pollinated leafy vegetable with significant heterosis. The use of heterosis is important for breeding high-yield Chinese cabbage hybrids. ...

Abstract:
... Fire is a frequent disturbance in most grasslands around the world, being key for the structure and dynamics of the biodiversity in such ecosystems. While grassland species may be resilient, little is known on how plant–pollinator networks reassemble after fire. Here, we investigate the structure and dynamics of plant–pollinator networks and the variation in species roles over a 2-year post-fire c ...

Abstract:
... Natural pollination of Vanilla species remains poorly understood. Our research aimed at better understanding the pollinator attraction mechanism of the Neotropical species Vanilla pompona. Based on our results, we hypothesize that the identified pollinator Eulaema cingulata is attracted via a dual mechanism combining floral fragrance rewards and food deception.

Abstract:
... Female individuals in the genus Arisaema are the only plants known to imprison their pollinators permanently. Their lethal pollination system has long attracted the interest of evolutionary biologists and naturalists. Nonetheless, the mechanisms of how Arisaema plants lure their victims to the brink of death are only just being unveiled. Here, I briefly review the unique reproductive biology of th ...
