Assessment of pollen viability and germinability in some European chestnut genotypes (Castanea sativa L.)

Horticultural Science, 2008
Pollen viability and germinability in some European chestnut genotypes was assessed in this study. In 10 chestnut genotypes, percentages of pollen viability were generally high and often around or over 80%.

Powerful yet challenging: mechanistic niche models for predicting invasive species potential distribution under climate change

Ecography, EarlyView.
Risk assessments of invasive species present one of the most challenging applications of species distribution models (SDMs) due to the fundamental issues of distributional disequilibrium, niche changes, and truncation. Invasive species often occupy only a fraction of their potential environmental and geographic ranges, as their spatiotemporal dynamics ...

Buck Wheat: Nutritional, Bioactive Characteristics, Health Benefits, and Side Effects

Future Postharvest and Food, EarlyView.
ABSTRACT Micronutrient deficits have resulted from an over‐reliance on a small number of cereal crops for food security. The agricultural sector faces severe sustainability issues due to the rapid growth of the world's population and sudden climatic changes.

Improvised Media for In Vitro Pollen Germination of some Species of Apocynaceae

International Journal of Environment, 2014
Pollen germination forms one of the most important stage post pollination prior to fertilization. This is essential for proper seed setting and seed development. In vitro pollen germination test is the most reliable way of assessing the pollen viability.

Selection for persistence of endophyte‐free meadow fescue under intensive grazing versus frequent mowing

Grassland Research, EarlyView.
Cattle grazing meadow fescue pasture in remnant oak savanna near Fennimore, Wisconsin. Abstract Background Meadow fescue (Schedonorus pratensis (Huds.) P. Beauv.) is highly adapted to managed rotational grazing systems with sufficient rest periods to promote regrowth and sward longevity.

Optimizing Wheat Pollen Preservation for Enhanced Viability and In Vitro Germination

Agronomy
Wheat pollen, which is characterized by its short lifespan, exhibits rapid germination after anthesis. The preservation of wheat pollen is contingent upon environmental factors including temperature, relative humidity, light, and wind.

Effect of bio‐fertilization and edapho‐climatic conditions on chickpea nodulation, grain yields, and seed protein in a Mediterranean context: a meta‐analysis approach

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Chickpeas (Cicer arietinum L.) serve as a protein‐rich staple, particularly in Mediterranean countries, where they are often grown in marginal and water‐stressed areas. This meta‐analysis synthesized evidence from peer‐reviewed publications across Mediterranean countries to assess how chickpea rhizobial inoculation influences chickpea ...

Resource limitation and competition shape reproductive allocation and synchrony

Oikos, EarlyView.
The dynamics of reproductive allocation (RA) in herbaceous plant communities, particularly in response to varying environmental conditions such as drought stress and competitive interactions, remain underexplored. This study aims to fill this gap by hypothesising that both belowground resource limitation and the presence of dominant species ...

Determination of Pollen Fertility of Some Cut Rose Varieties in Different Periods

Düzce University Faculty of Forestry Journal of Forestry
In rose breeding by hybridization, the viable pollen and germination rate of the male parent increases the rate of successful pollination. Therefore, a good variety of pollinators is always needed in hybridization studies.
