Woody ornamental plants with colorful or unusually shaped stems, buds, flowers, or fruits represent a growing specialty niche in cut flower production markets. These unique plants can be good prospects for off-season production, offering distinct benefits such as extended growing seasons, respectable financial returns, hardiness, and the ability to produce multiple harvests from single plantings.
A research team from the Department of Plant Science and Landscape Architecture at the University of Connecticut recently published the results of a poll of North American willow "cut stem" producers. The study was designed to identify willow growers' profiles, production acreages, and gross sales, to evaluate consistency in production practices, and to assess the prospective market value for crop expansion. According to Yulia A. Kuzovkina, corresponding author of the study, the potential exists to significantly expand the consumer market for woody cut stems, but until recently "woody floral crops have received little formal research attention to determine the best cultural practices for optimal yields".
Willow is among the most popular woody plant used in cut stem production operations; species and varieties exhibit a range of unique ornamental attributes, including showy catkins, brightly colored stems, and contorted, or "fasciated", stems. Willows are typically harvested during the late winter months when few plants are available for field production in temperate climates. Cash returns for willow growers can range from $1.25-1.75 per stem for species harvested for ornamental catkins, and annual gross financial returns for willow plants—reported at up to $24.94 per plant—are much higher than for many other woody florals.
The team distributed a survey to willow growers throughout North America. The survey included questions concerning business identity and cultural practices, including plant spacing, fertilization, irrigation, and pruning methods. Survey responses confirmed that willow was a supplemental source of income for most growers, complementing a larger product selection of woody and herbaceous species for cut flower production.
The majority of growers expressed the importance of including willow in their product selection and noted a desire to increase production acreage and extend seasonal markets. The responses also revealed what the research team refers to as "the nonscientific nature of willow production", evidenced by growers' wide variations in basic cultural practices, limited use of scientific plant names, and frequent inability to accurately identify their selections.
"This survey can help researchers to identify a set of questions to improve the understanding of the fundamentals of willow production through the development of precise commercial production practices, standardization of variety names, and stimulation of further development of this crop through market expansion", noted Kuzovkina.

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.
Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
