Pollen viability and in vitro germination of six pistachio (Pistacia vera L.) cultivars grown in northern Jordan

Advances in Horticultural Science, 2019
This study was conducted on six pistachio cultivars (Lazaourdi, Nab-El Jamal, Boundiki, Batouri, Marawhi and Aschouri) to investigate the percentage of pollen viability and in vitro pollen germination under stored and non-stored (fresh) conditions.

Germination and storage of pollen

Germination of pear pollen markedly improved when boric acid was added to the medium. The pollen was more sensitive to boron in water than in 10 % sugar solution. Supplying weak solutions of boron to pear branches before flowering resulted in a good germination of the pollen in sugar solution without boron.

Unshared on the top: strong segregation of pathogen communities between western honey bees and wild bees in a retreating glacier foreland

Oikos, EarlyView.
Shared flowers can facilitate pathogen transmission between managed honey bees and wild bees, yet this process remains poorly understood in ecosystems undergoing rapid environmental change. Using a glacier foreland in Switzerland, we present the first study on how glacier retreat stages and bee life‐history traits influence pathogen occurrence across ...

Cryogenic Storage of Olive Pollen

Journal of the American Pomological Society
The possibility of using liquid nitrogen storage conditions (−196°C) for the storage of olive ( Olea europaea) pollen was demonstrated. Pollen from 10 cultivars was rapidly frozen and thawed. Germination tests were performed on 15% sucrose, 1% agar plates. Significant differences between unfrozen control samples and frozen pollen samples were not found.

Feast or famine: How food deserts, wealth and greenspace correlate with coyote diets in Seattle, Washington

People and Nature, EarlyView.
Abstract Urban environments create unique challenges for wildlife, where dietary habits may reflect both ecological heterogeneity and societal disparities. In this study, we explored how social factors such as household income and human population density, and ecological factors such as tree canopy correlate with coyote (Canis latrans) diets in Seattle,

Assessing terrestrial vertebrates as potential biodiversity indicators of ecosystem services in multifunctional landscapes

People and Nature, EarlyView.
Abstract Combining ecosystem services and biodiversity conservation is critical for evaluating the benefits of nature to society. However, research gaps have led to a conservation dilemma in determining which biodiversity groups should be selected in ecosystem service assessments.

Factors Influencing Date Pollen Viability

Journal of Agricultural and Marine Sciences, 1997
Pollen of seven date cultivars was stored at 4.5 -5.0'C using desiccator with or without silica gel and in vials outside the desicator as a control. Germination percentage was determined microscopically with a hemacytometer after harvest and at three and

Open‐land‐derived agroforestry and effects of abandonment of management of the main crop on ecosystem services and woody plant diversity

PLANTS, PEOPLE, PLANET, EarlyView.
Tropical forests are rapidly declining. One promising strategy to reverse the loss of tropical forest is the establishment of agroforestry on open land. We combined interviews with biodiversity surveys to learn general lessons from success and nonsuccess stories of the establishment of open‐land‐derived coffee agroforests in one of the world's ...

Room-Temperature Storage of Coconut Pollen [PDF]

Nature, 1962
POLLEN introduction and exchange have been suggested as a means of broadening the scope of breeding programmes designed to produce disease-resistant and high-yielding coconuts1–3; and at a recent meeting of the Food and Agriculture Organization Technical Working Party on Coconut Production it was stressed4 that the most important material question to ...

Capsicum chinense as an African traditional vegetable: Culture, resilience, and opportunity

PLANTS, PEOPLE, PLANET, EarlyView.
Capsicum chinense is central to everyday diets, cultural identity, and smallholder livelihoods across Sub‐Saharan Africa, yet remains overlooked in agricultural research and policy. This paper reframes C. chinense as a traditional, climate‐resilient vegetable shaped by centuries of farmer stewardship and cultural selection.
