Our research focused on the reproductive phenology of Mauritiella armata, a key veredas species in southeastern Brazil, and aspects its floral fruit morphology sexual system. We observed phenological patterns M. armata for 36 months, examined relationships between phenophases environmental variables to describe relation filters, as well morphologies, system (to evaluate dioecy), biometry parts....

The timing of life history traits is central to lifetime fitness and nowhere is this more evident or well studied as in the phenology of flowering in governing plant reproductive success. Recent changes in the timing of environmental events attributable to climate change, such as the date of snowmelt at high altitudes, which initiates the growing season, have had important repercussions for som...

The buriti, Mauritia flexuosa, is the most common palm in Brazil, where it has considerable ecological and economic importance. However, few data are available on the phenology of the species, mainly in coastal restinga ecosystems. The present study monitored the reproductive phenology of M. flexuosa in the restinga of Barreirinhas, in the Brazilian Northeast, and investigated the relationship ...

BACKGROUND AND AIMS Flowering phenology is a potentially important component of success of alien species, since elevated fecundity may enhance invasiveness. The flowering patterns of invasive alien plant species and related natives were studied in three regions with Mediterranean-type climate: California, Spain and South Africa's Cape region. METHODS A total of 227 invasive-native pairs were ...

to study the effect of water deficit and plant density on yield and yield components of cumin (cuminum cyminum), an experiment was conducted during the 2002 - 2003 growing season at research farm of zabol university. in this study, the effects of plant density (25, 50, 100, 150, and 200 plants per m²) and water stress (before flowering, flowering, seed filling and seed hardening vs adequate irr...

Summary Background The grass pollen season is characterized by a particularly long duration, covering the months May to July in Europe but can vary depending on altitude and geographical location. Methods Three species whose flowering period takes place late are discussed detail: Phragmites australis (common reed), Miscanthus spp. (silvergrass), Zea mays (maize). Results flowers between August ...

Extending the period of fruit production is a way to substantially increase crop yield in many fruit or ornamental species. In the cultivated octoploid strawberry (Fragaria × ananassa), the most consumed small fruit worldwide, fruit production season can be extended by selecting the perpetual flowering (PF) cultivars. This trait is of considerable interest to growers and to the food industry. F...

To analyze the extent to which early flowering of specialized myrmecochorous plants (i.e. plants producing elaiosome-bearing seeds) may be the result of adaptation for ant dispersal, we investigated flowering and fruiting patterns of common herb and shrub-layer species in a beechwood forest at the western end of the Cantabrian Range (Spain). Over the same period, we estimated ant abundance, the...

Many woody perennials, such as poplar (Populus deltoides), are not able to form flower buds during the first several years of their life cycle. They must undergo a transition from the juvenile phase to the reproductive phase to be competent to produce flower buds. After this transition, trees begin to form flower buds in the spring of each growing season. The genetic factors that control flower...

The impact of the season on flowering time and the organization and morphogenesis of the reproductive structures are described in three tomato mutants: compound inflorescence (s), single flower truss (sft), and jointless (j), respectively, compared with their wild-type cultivars Ailsa Craig (AC), Platense (Pl), and Heinz (Hz). In all environmental conditions, the sft mutant flowered significant...
