Some evidence suggests a connection between outdoor recreation participation and
stronger environmental worldviews. This study finds little evidence supporting
participation in outdoor recreation activities and stronger environmental worldviews and
some evidence supporting a weak connection between appreciative outdoor recreation
and stronger environmental worldviews. Additionally, the study documents greater
participation in...
In recent years, there has been renewed interest in black raspberry (Rubus
occidentalis L.) breeding. This has been spurred, in part, by an increase in black
raspberry consumption due to studies that have shown them to be particularly high in
anthocyanin content indicating high levels of antioxidants. Present cultivars are...
Experiments focusing on plant growth regulators’ concentrations and combination, mineral salt formulations and TDZ pretreatment formations were conducted to optimize in vitro shoot regeneration from leaf and petiole explants of 'Marion' blackberry. Optimum shoot formation was obtained when stock plants were incubated in TDZ pretreatment medium for three weeks before...
Strawberry is one of four crops included in the USDA-NIFA Specialty Crop Research Initiative-funded RosBREED project along with apple, peach, and cherry. Phenotyping strawberry for specific horticultural and commercial traits is important to identify associations with genotypic marker(s). This process is the first step in translating genomic knowledge into enhanced...
In recent years, there has been renewed interest in black raspberry (Rubus occidentalis L.) breeding. This has been spurred by an increase in black raspberry consumption due to studies that have shown them to be particularly high in anthocyanin content indicating high levels of antioxidants. Present cultivars are ill adapted...
Nuclear DNA flow cytometry was used to differentiate ploidy level and determine nuclear DNA content in Rubus. Nuclei suspensions were prepared from leaf discs of young leaves following published protocols with modifications that included: increasing the stain concentration, adding the stain after the RN ase treatment instead of adding it...
Hereditary variation is a vital component in the development of new and improved cultivars of landscape plants. Sources of hereditary variation include naturally occurring variation, recombination due to controlled crosses, artificial mutagenesis, and genetic modification via biotechnology. Here I explore all methods with the exception of genetic modification via biotechnology....
This publication describes raspberry cultivars, including red, yellow, black, and purple types. It explains the difference between floricane-fruiting and primocane-fruiting cultivars, includes information on commercial value, and identifies which cultivars work well for home gardens.
This publication describes blackberry cultivars, including trailing, erect, semierect, primocane-fruiting erect, and blackberry/red raspberry hybrids. It includes information on commercial value and identifies which cultivars work well for home gardens.
The cultivated strawberry, Fragaria x ananassa, resulted from a cross between two wild strawberries: Fragaria virginiana (meadow strawberry), which is native throughout much of North America, and Fragaria chiloensis, which is native to the Pacific coast of North and South America. Colonists in eastern North America sent the meadow strawberry,...

This publication briefly describes raspberry
cultivars. The two main types of raspberries are
red and black. Yellow-fruited raspberries result
from a mutation of red raspberries that prevents
the formation of red color; they are grown exactly
the same as red raspberries. Purple raspberries are
a hybrid between black and red...
Strawberry is economically the most important berry crop grown worldwide and breeders are continuously striving to develop improved cultivars. So far, marker assisted breeding (MAB) in strawberry has been limited to the private sector. However, loci controlling some traits of economic importance such as perpetual flowering (PF) and soluble solids...
This publication describes strawberry cultivars, including June-bearing, everbearing, and day-neutral types. It includes information on commercial value and identifies which cultivars work well for home gardens.
This publication describes blueberry cultivars, including northern highbush, southern highbush, rabbiteye, lowbush, and half-high types. It includes information on commercial value and identifies which cultivars work well for home gardens.
Pre-existing Expressed Sequence Tag (EST) libraries (1,305 sequences) and a newly constructed microsatellite-enriched genomic library (136 clones) from the V. corymbosum cultivar 'Bluecrop' were screened for unique Simple Sequence Repeat (SSR)-containing sequences. Our goal was to develop a set of robust SSR markers for use in managing the National Clonal...
A lack of genetic diversity in cultivated black raspberry (Rubus occidentalis L.) germplasm has been widely recognized as a major factor limiting progress towards breeding improved cultivars. Despite this, little effort has been made since the early twentieth century to systematically collect and evaluate wild black raspberry for germplasm improvement....
Reed Canarygrass (RCG) is an aggressive invader in aquatic ecosystems that swiftly modifies the environment and decreases biodiversity. A physical model was used to investigate the mechanisms by which RCG spreads. Experimental trials were implemented to examine feedbacks between a mid-channel patch of the flexible RCG, hydraulics, and bedform evolution...
Two studies used DNA markers to assess their usefulness in germplasm identification and evaluation of genetic stability in four cryopreserved Rubus accessions that were stored for over 10 years in liquid nitrogen. In the first study, 12 robust Simple Sequence Repeat (SSR) markers were developed from two microsatellite-enriched libraries of...
