MR439: An Evaluation of Turfgrass Species and Varieties: Fineleaf fescues

The fineleaf fescues comprise 28 species of perennial grasses in the genus Festuca. The fescue species represented in the United States include deeply rooted grasses with both wide and narrow leaf types, bunch and spreading plant morphologies, and tolerances to a wide variety of environmental conditions. Several of these species exhibit desirable characteristics for turfgrass use: adaptation to cool, humid regions, tolerance to droughty acidic soils, excellent wear and shade tolerance, deep, erosion-resistant root systems and rapid recovery following mowing. This report presents the results of Maine trials in the 1998 National Turfgrass Evaluation Program (NTEP) Fineleaf Fescue Trial, which evaluated 79 varieties representing four species: Chewing’s fescue, creeping red fescue, hard fescue, sheep fescue, and blue sheep fescuehttps://digitalcommons.library.umaine.edu/aes_miscreports/1013/thumbnail.jp

MR437: An Evaluation of Turfgrass Species and Varieties: The bentgrasses

In the genus Agrostis, the four species employed as turfgrasses include creeping bentgrass (A. palustris Huds., A. stolonifera L.), colonial bentgrass (A. tenuis, A. capillaris), velvet bentgrass (A. canina), and, more rarely, redtop (A. alba, A. gigantea). The objective of this four-year study was to evaluate the performance of 29 commercially available bentgrass cultivars under the environmental conditions of central Maine.https://digitalcommons.library.umaine.edu/aes_miscreports/1012/thumbnail.jp

MR416: An Evaluation of Turfgrass Species and Varieties: Perennial Ryegrass

The ryegrasses include those popular and extensively used turfgrasses noted for their rapid germination and subsequent swift development into a suitable turf. These grasses are broadly adapted to cool temperate climates and find use in a wide array of habitats: from the seashore to mountain slopes, and in nearly all soil conditions. This report presents the results of a trial of 97 perennial ryegrass varieties at the University of Maine.https://digitalcommons.library.umaine.edu/aes_miscreports/1006/thumbnail.jp

MR430: An Evaluation of Turfgrass Species and Varieties: Tall Fescue

Originating in Europe, Tall fescue (Festuca anundinacea Schreb.) is a coarse-textured grass, which is characterized by a bunch-type growth habit. Tall fescue possesses a deeper, coarser and more extensive root system than the other cool- season species giving this grass excellent drought tolerance. It is propagated by seed, with an establishment rate that is more rapid than Kentucky bluegrass, but slower than perennial ryegrass. In conclusion, the improved tall fescue varieties performed surprisingly well at the Littlefield Garden at the University of Maine. Based upon this performance, this species should be given consideration as a cool-season turf species in those situations where its demonstrated attributes are consistent with the turf needs of that location and/or situation.https://digitalcommons.library.umaine.edu/aes_miscreports/1022/thumbnail.jp

MR441: An Evaluation of Turfgrass Secies and Varieties: Kentucky Bluegrass

The bluegrasses rank highest among those grasses used as amenity turfgrasses. They comprise the most important, most popular, and the most richly colored of all turfgrasses and have found excellent adaptation in the United States, Europe, and the cooler regions of Asia. The bluegrasses, and in particular the Kentucky bluegrasses, have been subjected to the most rigorous breeding and screening efforts, with the resulting release of the greatest numbers of improved cultivars of any turfgrass species. The 2000 National Turfgrass Evaluation Programs (NTEP) Kentucky Bluegrass Trial (High Maintenance) included 173 cultivars that were evaluated for their tolerance to and performance under normal mid-Maine conditions.https://digitalcommons.library.umaine.edu/aes_miscreports/1014/thumbnail.jp

Salt Damage to Northern White-Cedar and White Spruce

Five-year-old transplants of northern white-cedar and white spruce were treated with tap water applied to the soil and with various concentrations of sodium chloride in distilled water, applied either to the soil or to the foliage. Observations were made on the gross morphological effects and anatomical effects of the treatments. Morphological damage included discoloration and loss of foliage. The most significant anatomical damage included fragmented cuticle, disrupted stomata, collapsed cell walls, disorganized or disintegrated protoplasts, coarsely granular cytoplasm, disintegrated chloroplasts, disintegrated nuclei and disorganized phloem. While there appeared to be no outstanding anatomical differences between the effects of soil versus foliar applications, both species did show somewhat less damage by soil-applied than by foliar-applied salt. It was not possible to conclusively assign the cause of morphological or anatomical damage to indirect effects, such as water deficiency or to ion toxicity of the salt. However, the results did suggest that northern white-cedar may be somewhat more salt-tolerant than white spruce
