Requiring students to create weed collections is a common technique for teaching weed identification. Data compiled over 18 years from students' weed collections in a college-level course included over 350 species of plants. Almost half of the specimens belonged to the Asteraceae or Poaceae. The 30 most frequently collected species accounted for…

Soybean yield potential can be increased by increasing the number of pods per plant, which can be achieved by increasing the number of nodes per plant while decreasing internode length to prevent lodging due to excessive height. In an effort to discover the genetic variability for this trait, a genome wide association study (GWAS) was performed on…

With the onset of global change, forest species diversity has declined in recent decades as pristine habitat in biological hotspots rapidly diminishes. Many carbon mitigation efforts directed at decreasing emissions from forest degradation and destruction assume that faunal biodiversity will benefit from such efforts. Yet, conservation of faunal…

Plant blindness, the inability of people to notice plants, is of current interest in the natural sciences community. It has been hypothesized that communities of varying cultures may have improved plant sight. Researchers used an online survey to assess citizens ability to identify plants. The survey also intended to address the concern of elders…

Use of demonstration plots showcasing native forbs and grasses in public greenspaces or along well-traveled paths can be helpful in increasing awareness of beneficial plant species. Signage can be used as an educational delivery method--such as that used in arboretums and museums--to bring awareness of the importance of biodiversity, pollinators,…

The sunflower head moth is considered the most damaging pest to sunflowers in Kansas. This small cigar shaped moth can severely impact the yield of commercial sunflowers. A sunflower plant infested with sunflower head moth larvae can also become very susceptible to Rhizopus fungi which causes head rot and can significantly add to the economical…

Basic quantitative and population genetics topics are typically taught in introductory plant breeding courses and are critical for success in upper-level study. Active learning, including simulations and games, may be useful for instruction of these concepts, which rely heavily on theory and may be more challenging for students. The statistical…

It has been speculated that most people have plant blindness, meaning plants go unnoticed by the majority of the population. This study sought to combine the knowledge of multiple disciplines to determine evidence of plant blindness through children's drawings. To do this, third-grade students were introduced to native prairie and wetland plants…

An introductory plant science lab offered by the Department of Agronomy & Horticulture at the University of Nebraska-Lincoln was adapted for online delivery. This paper describes the adjustments made for online delivery and examines students' perceptions of learning and engagement from surveys administered in both the in-person and online…

The coffee bean is the most important agricultural product in international trade; it ranks second behind petroleum in product exports worldwide. An estimated 15 billion coffee trees are being grown to meet this demand, and the work that goes into this directly contributes to the income of 25 million small producers worldwide. Due to the…

Plant identification is a critical skill for students in biological sciences, especially forestry. Many students begin with limited plant identification abilities and struggle to learn this skill. To support student learning of identification and ecological characteristics of important forest plants in an undergraduate forest ecology course at the…

Food security is one of the most pressing concerns of our times. Despite the vast opportunities, there is a shortage of skilled professionals in the food, agriculture, and plant sciences. Although most programs focused on addressing this concern have targeted students, we have often overlooked another critical group--the teachers. To address this…

The world population is expected to reach 9.2 billion by the year 2050. Farmers are faced with the daily challenge of how to feed these people while availability of land and water is dwindling. The growth rates of global agricultural production and crop yields have slowed in the last couple of years, raising fears that the world may not be able to…

Hypoxic and anoxic stresses on mesophytes cause a waste of plant productivity. Many phenotypic responses of roots to hypoxia have long been known, and now genotypic and biochemical responses are being elucidated. Hypoxia causes activation of dozens of specific genes that help the plant to survive hypoxia. It is now clear that mesophytes actively…

Arbuscular mycorrhizae fungi (AMF) play a large role in the current understanding of the soil ecosystem. They increase nutrient and water uptake, improve soil structure, and form complex hyphal networks that transfer nutrients between plants within an ecosystem. Factors such as species present, the physiological balance between the plants in the…
