Native tree shows potential for Utah's high desert region

Researchers in Utah selected superior accessions of native bigtooth maple (Acer grandidentatum) trees using aerial digital images taken during peak fall color. Trees were physically located using GPS technology then visually evaluated for initial selection; six trees were selected for propagation. Experiments showed that the optimum time for chip budding scions of wild accessions in northern Utah is July through mid-August, and that opportunity exists for successful budding of wild bigtooth maples in the region.

Study of consumer preferences finds fragrance is key

The IdeaMap® software suite and the concept of Mind Genomics® were applied to analyze which features of flower products influence consumer perception. Researchers created a database to define how individuals perceive distinct components of an overall flower product. Results showed that the highest and lowest interest values were for elements in the "flower fragrance" category, indicating that fragrance is important with respect to consumer satisfaction.

'NuMex Cinco de Mayo', 'NuMex Thanksgiving' most tolerant in experiments with saline irrigation water

Horticulturists studied the relative salt tolerance of 10 cultivars of ornamental chile peppers by irrigating mature plants with saline solutions and germinating seeds in saline substrate in a greenhouse. Experiments showed that 'NuMex Cinco de Mayo' and 'NuMex Thanksgiving' were the most tolerant of the cultivars in study, while 'NuMex Christmas' and 'NuMex Memorial Day' were the least salt-tolerant varieties. The eight other varieties tested were determined to be moderately salt tolerant.

Soil quality "not adversely affected" in study of convention and organic vegetable production

A study compared soil under high tunnels with soil in adjacent fields over 8 years. The data showed elevated soil salinity under high tunnels, particularly with the organic management system, but the increase was not enough to be detrimental, even to sensitive crops. The researchers determined that overall soil quality was not adversely affected in the experiments with conventionally or organically produced vegetable crops.

Amendments of biosolids found more effective, longer lasting than yard waste compost

A study evaluated three approaches to improving the persistence of perennial turfgrasses on roadsides in Rhode Island. Researchers tested soil amendment with organic matter, the use of improved turfgrass cultivars, and the use of alternate turfgrass species. Soil amendment was more effective than either improved genetics or salt tolerance. Establishment, vertical growth, and persistence of vegetation cover were significantly improved by amendment with organic matter, particularly biosolids.
