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%.

Characterization of a novel R98Q mutation that confers resistance to sulfentrazone in common ragweed (Ambrosia artemisiifolia) populations from Michigan

Pest Management Science, EarlyView.
Field‐collected Ambrosia artemisiifolia populations from Michigan, USA, soybean fields exhibited strong resistance to the protoporphyrinogen IX oxidase (PPO)‐inhibiting herbicide sulfentrazone and reduced sensitivity to fomesafen. Target‐site analysis identified a novel Arg‐98‐Gln (R98Q) substitution in PPO2, co‐occurring with the previously reported ...

Do spatially targeted weed management strategies increase risk of herbicide resistance evolution?

Pest Management Science, EarlyView.
Spray‐buffers reduce the effect of detection inaccuracies in spot spraying. We found a trade‐off between short‐term weed population control efficacy and long‐term prevention of herbicide resistance evolution. Abstract Background Spatially targeted spraying is an alternative to broadcast herbicide application that reduces herbicide use by restricting ...

The Arabidopsis KINβγ Subunit of the SnRK1 Complex Regulates Pollen Hydration on the Stigma by Mediating the Level of Reactive Oxygen Species in Pollen.

PLoS Genetics, 2016
Pollen-stigma interactions are essential for pollen germination. The highly regulated process of pollen germination includes pollen adhesion, hydration, and germination on the stigma. However, the internal signaling of pollen that regulates pollen-stigma

MicroPoem: experimental investigation of birch pollen emissions [PDF]

, 2010
Diseases due to aeroallergens constantly increased over the last decades and affect more and more people. Adequate protective and pre-emptive measures require both reliable assessment of production and release of various pollen species, and the ...

Commercial Product Based on Metarhizium Anisopliae Affects Survival, Midgut Morphology, and Behavior in the Stingless Bee Scaptotrigona depilis (Hymenoptera: Apidae)

Environmental Toxicology, EarlyView.
ABSTRACT Brazilian social stingless bees are important pollinators and producers of honey, wax, royal jelly, propolis, and other products. These species are experiencing a population decline, attributed to different factors, such as the excessive use of pesticides.

Influence of temperature, germination duration and cultivar on in vitro pollen germination and pollen tube growth in coconut [PDF]

, 2017
Not AvailableTemperature, germination duration and cultivars are important factors influencing pollen germination and pollen tube length of plants and thereby effecting fruit set and yield. To quantify the influence of nine temperatures from 10°C to 50°C

Precipitation‐mediated asymmetric fitness consequences of nectar robbing in distylous Primula florindae

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Flowers with deep corollas are frequently associated with nectar robbing, a behaviour that often reduces pollen transfer and seed production. Robbing scars, however, may further affect plant reproductive success through rainwater entry into corolla tubes.

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.
