The Analysis and Interpretation of Seedling Recruitment Curves [PDF]

open access: yes, 1993
We derive spatially explicit population models for the interaction between a species of annual plant and a community of perennial species. The models are used to explore the conditions for persistence of the annual in both a constant and a stochastic ...

Studies on the behavior of some cultivars of Dahlia in the Botanical Garden Cluj-Napoca

open access: yesRomanian Journal of Horticulture
Dahlias are particularly appreciated due to the elegance of the inflorescences and the long duration of flowering, which gives them multiple uses both in floral art and in landscaping.

The Impact of Grazing on the Grass Composition in Temperate Grassland

open access: yesAgronomy, 2020
Grazing is one of the predominant human activities taking place today inside protected areas, with both direct and indirect effects on the vegetation community. We analyzed the effects of grazing intensity on grass composition during four grazing seasons

The effect of AMF suppression on plant species composition in a nutrient-poor dry grassland. [PDF]

open access: yesPLoS ONE, 2013
Arbuscular mycorrhizal fungi (AMF) are expected to be one of the key drivers determining the diversity of natural plant communities, especially in nutrient-poor and dry habitats.

Combined genetic, genomic and physiological approaches to characterize flowering in Fragaria [W324] [PDF]

open access: yes, 2015
Flowering is a key event for production of seeds or fruits. To date, studies of this process were mainly focused on the molecular mechanisms involved in the control of flowering until now.

Subgenome Dominance in Allotetraploid Actinidia valvata Regulates RNA m6A Modification for Waterlogging Tolerance

open access: yesAdvanced Science, EarlyView.
The waterlogging tolerance of allotetraploid Actinidia valvata is inherited from one of its diploid progenitors, which leads to subgenome expression dominance, mediated by complex mechanisms including altered chromatin accessibility and DNA methylation.

Water relations of woody perennial plant species

open access: yesOENO One, 2007
Aims: To describe the relation of various water status measures of woody perennial plants (predawn and midday stem and leaf water potential), to indices of physiological activity such as leaf conductance, vegetative growth and fruit growth and ...

Molecular mechanisms of flowering phenology in trees

open access: yesForestry Research, 2023
Flower initiation is a phenological developmental process strictly regulated in all flowering plants. Studies in Arabidopsis thaliana, a model plant organism in plant biology and genetics, and major cereal crops have provided fundamental knowledge and ...

Florigen and Florigen‐Like Genes Regulate Temperature‐Responsive Flowering in Tomato

open access: yesAdvanced Science, EarlyView.
This study uncovers that FLOWERING LOCUS T‐Like 2 (FTL2) and SINGLE‐FLOWER TRUSS (SFT) antagonistically regulate temperature‐responsive flowering in the tomato shoot apical meristem. High temperature induces floral repressor FTL2, which directly inhibits SFT to delay short‐day floral transition, while SFT reciprocally inhibits FTL2 to promote flowering.

Perennial crops can complement semi-natural habitats in enhancing ground beetle (Coleoptera: Carabidae) diversity in agricultural landscapes

open access: yesEcological Indicators, 2021
Agricultural intensification has caused losses of global biodiversity and associated ecological services. Agroecological landscape assessments are therefore often based on the area of remaining semi-natural habitats due to their ability to promote ...
