Performance of Russet Norkotah line selections at different rates of nitrogen
Russet Norkotah line selections may be utilized to increase yields and profitability while reducing nitrogen applications normally required when producing Russet Norkotah. The Solanum tuberosum L. cultivar, Russet Norkotah, ... -
Evaluation of plant characteristics and disease resistance in Cu-ipt transformed watermelon cv. crimson sweet
Watermelon cv. Crimson Sweet was transformed with the copper inducible isopentenyl transferase gene (Cu-ipt) via Agrobacterium mediated gene transformation process. The ipt gene governs the rate-limiting step in the cytokinin ... -
Environmental stress aspects of saltgrass [Distichlis spicata (L.) Greene]
Saltgrass [Distichlis spicata (L.) Greene] is undergoing preliminary evaluation at Colorado State University for use as a turfgrass in adverse environments. Furthermore, it has a potential as a range species in saline-alkali ... -
Biocontrol of fusarium crown and root rot of fresh market tomato with trichoderma harzianum strains under greenhouse conditions
Greenhouse tomato growers in the United States have few products available for chemical control of plant pathogens. Biological control of soilborne plant pathogens by antagonistic microorganisms is a potential alternative ... -
Seed dormancy in Callirhoe involucrata (Torr. & Gray) Gray, (Malvaceae)
Propagation of Callirhoe involucrata (Torr. & Gray) Gray, for use as a landscape ornamental has been encumbered by a lack of understanding of the seed dormancy and the development of a practical technique for overcoming ... -
Salinity tolerance and associated salinity tolerance mechanisms of four turfgrasses
The need for salinity tolerant turfgrasses is increasing because of the increased use of effluent or other low quality water for turfgrass irrigation. Greenhouse container and hydroponic experiments were conducted to ... -
Physiological, morphological, and spectral reflectance characteristics of Kentucky bluegrass, Texas bluegrass, and their hybrids in response to water stress
Demands on fresh water resources, especially throughout the arid and semi-arid western USA, have resulted in escalation of government regulations to force water conservation. Such measures have included limitations on the ... -
Overexpression of mannitol-1-phosphate dehydrogenase increases mannitol production and confers salt and chilling tolerance in transgenic petunia cv. Mitchell
Diploid petunia plants (Petunia hybrid, cv. Mitchell) transformed with a bacterial gene (mt/ D) encoding mannitol-1-phosphate dehydrogenase enzyme (MTL D), resulting in high mannitol expression, were developed and studied ... -
Development and testing of a greenhouse assay for screening potato germplasm for susceptibility to Spongospora subterranea f. sp. subterranea (powdery scab)
Potato resistance to powdery scab, caused by the protist Spongospora subterranea f. sp. subterranea (S.s.s.), has become extremely important in recent years due to the increased damage caused by this disease. Variable field ... -
Overcoming seed dormancy in Glaucium Spp. (Papaveraceae)
The Horned Poppy, Glaucium sp., is a potential candidate for introduction as an herbaceous perennial to Colorado. However, its introduction has been hindered by poor germination, less than 10% in informal studies across ... -
Comparative analysis of antioxidant properties, quality attributes and yield of organically and conventionally grown melons (Cucumis melo L.) and tomatoes (Solanum lycopersicum L.)
Fresh fruits and vegetables including melons and tomatoes have gained considerable prominence in the American diet due to increasing awareness of their potential health and nutrition benefits. Consumers are starting to ... -
Influence of storage temperature and time in storage on pigment content of potato (Solanum tuberosum L.)
Anthocyanins are responsible for different colors in many plant species including potato tubers. They are also one of the important components in human health as antioxidants. Important factors that can affect anthocyanin ... -
Phenotypic variability, cold hardiness and flowering induction of saltgrass [Distichlis spicata (L.) Greene] clones
With increased population growth and periodic droughts in the semiarid U.S. west, there is interest in developing alternative turfgrass species that are water efficient and tolerate poor quality water. Colorado State ... -
Effects of topdressing established Kentucky bluegrass with composted manure
Concerns about water quality issues surrounding nutrient loading into surface and ground water from agricultural manure applications have contributed to the increasing interest in composting manure and topdressing it on ... -
