Influence of pollination mechanisms on the physical-chemical quality of strawberry (Fragaria x ananassa) cv. San Andreas [PDF]

Anais da Academia Brasileira de Ciências
The objective of this study was to evaluate the physical-chemical quality parameters of strawberry fruits, cultivar San Andreas, depending on different pollination mechanisms.

The spread of non‐native species

Biological Reviews, EarlyView.
ABSTRACT The global redistribution of species through human agency is one of the defining ecological signatures of the Anthropocene, with biological invasions reshaping biodiversity patterns, ecosystem processes and services, and species interactions globally.

Self-Pollinated Types and Ecological Adaptations of the Desert Plant Gymnocarpos przewalskii

Plants
In desert plants, outcrossing is frequently limited by pollinator scarcity, leading to a certain percentage of self-fertilization. However, research on the ecological adaptations of self-fertilized seeds remains limited.

Controlled pollinations reveal self-incompatibility and inbreeding depression in the nutritionally important parkland tree, Parkia biglobosa, in Burkina Faso

Journal of Pollination Ecology, 2018
The socioeconomically important fruit tree Parkia biglobosa is becoming less abundant in the West African savannah, possibly due to poor regeneration.

Towards a simplified taxonomy of Capsella bursa-pastoris (L.) Medik. (Brassicaceae) [PDF]

, 1999
Capsella bursa-pastoris (L.) Medik. is a species with a cosmopolitan distribution which shows considerable morphological variation. Numerous authors have recognised widely differing numbers of varieties, microspecies or other infraspecific subdivisions

Aneuploidy among androgenic progeny of hexaploid triticale (XTriticosecale Wittmack). [PDF]

, 2010
Doubled haploids are an established tool in plant breeding and research. Of several methods for their production, androgenesis is technically simple and can efficiently produce substantial numbers of lines.

Early evolutionary history of the seed

Biological Reviews, EarlyView.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

The effect of the limitation of insect pollination period on the fruit set and yield of temperate-zone fruit tree species

International Journal of Horticultural Science, 2000
The duration of effective bee pollination period was limited by caging flowering branches for shorter or longer time in blooming fruit trees in a number of experiments during the past decades.

How genomics fuel breeding: unraveling the structure of infectious eBSV lead to the end of the BSV constraint for breeding banana interspecific hybrids [PDF]

, 2014
Infections of banana and plantain by banana streak viruses (BSV) can occur in the absence of vector-mediated transmission, through the activation of infectious endogenous BSV sequences (eBSVs).
