Balancing Forage Production, Seed Yield, and Pest Management in the Perennial Sunflower Silphium integrifolium (Asteraceae)

Agronomy, 2020
The perennial sunflower Silphium integrifolium Michx. (Asteraceae), also known as silflower, is a prospective dual-purpose forage plus grain crop. Pre-flowering biomass harvest for animal feed and the subsequent delay in plant growth and anthesis has the

Mercury cycling during the last glacial period in Arctic Lake El'gygytgyn, NE Russia

Journal of Quaternary Science, EarlyView.
ABSTRACT Tectonic processes play a key role in the global mercury (Hg) cycle on geological timescales, by mobilising Hg from deep Earth reservoirs to the surface. These natural fluxes also introduce a dynamic component to the terrestrial Hg cycle that can interact with other environmental signals and influence Hg delivery to sedimentary records.

A Land Potential‐Based Framework for Wind Erosion and Sand and Dust Storm Source Mitigation

Land Degradation &Development, EarlyView.
ABSTRACT Wind erosion and sand and dust storms are a global challenge. While many management practices to mitigate sources of wind erosion and sand and dust storms have been documented, existing guidance largely emphasizes what practices are available, with limited information on where and under what ecological conditions they should be applied.

Development of Perennial Wheat Through Hybridization Between Wheat and Wheatgrasses: A Review

Engineering, 2018
Wheatgrasses (Thinopyrum spp.), which are relatives of wheat (Triticum aestivum L.), have a perennial growth habit and offer resistance to a diversity of biotic and abiotic stresses, making them useful in wheat improvement. Many of these desirable traits

Kernza in Wyoming: Perennial Grains for Vulnerable Lands

Agronomy
Kernza®, a perennial grain crop created from intermediate wheatgrass (Thinopyrum intermedium), has the potential to mitigate soil degradation in semiarid croplands of the Northern High Plains. From 2021 to 2023, Kernza was grown for the first time in Wyoming and compared at the field scale to winter wheat–fallow and Conservation Reserve Program (CRP ...

Past, present and future of local crop evolution

PLANTS, PEOPLE, PLANET, EarlyView.
Promoting agrobiodiversity is a promising strategy for mitigating the negative effects of climate change on global food security. We highlight the central role evolutionary processes play in harnessing the potential of local crops by integrating genomics, archaeology, ethnobotany and traditional ecological knowledge (TEK).

Autotetraploid Breeding in Perennial Rye (Secale cereanum): Cytogenetic Challenges, Agronomic Potential, and Future Prospects

Notulae Botanicae Horti Agrobotanici Cluj-Napoca
Perennial rye (Secale cereanum), an interspecific hybrid derived from cultivated rye (Secale cereale L.) and perennial wild rye (Secale strictum), has potential for the development of more sustainable perennial cereal systems.

The pistil as a traffic light: Yellow‐to‐red color change likely influences pollinator visitation patterns in Saxifraga fortunei (Saxifragaceae)

PLANTS, PEOPLE, PLANET, EarlyView.
Flowers can communicate reproductive status to pollinators through visual cues. In Saxifraga fortunei, pistils often changed from yellow to red after pollination, and hoverflies and honeybees preferentially visited flowers with yellow pistils. This pattern suggests that a post‐pollination color shift confined to the pistil can reduce revisits to ...

Perennial grain crops: A synthesis of ecology and plant breeding

Renewable Agriculture and Food Systems, 2005
AbstractPerennial grain crops would address many agricultural problems, including soil erosion, nutrient loss and pesticide contamination. Doubts about the possibility of perennial grain crops rest upon two assumptions: (1) that the relationship between yield and longevity is a fixed function that cannot be influenced by selection, mutation or ...

Sampling for Socially‐Inclusive Adoption Studies (SSAS): A new interdisciplinary sampling method for DNA‐fingerprinting‐based crop varietal adoption studies

PLANTS, PEOPLE, PLANET, EarlyView.
DNA fingerprinting is becoming the standard measurement procedure in crop adoption studies in the Global South, yet the lack of systematic and intentional sampling regarding which farmer to go to the plot with may bias results from these methods. We introduce a methodological innovation, Sampling for Socially Inclusive Adoption Studies (SSAS), to offer
