Perennial grasses, which can provide large amounts of biomass over multiple years, are one option being investigated to grow on marginal agricultural land. Introduction Recently, a grass species (Brachypodium distachyon) has been developed as a model to better understand grass Biomass yield is an important component to consider in any physiology and ecology. Here, we report on the flowering program designed to derive energy from plant material. time variability of natural Brachypodium accessions in Plant size and architecture are important biomass yield response to temperature and light cues. Changes in both parameters, and these parameters are often quite variable environmental parameters greatly influence when a given within a given species. Intraspecies variation in biomass accession will flower, and natural Brachypodium accessions yield can be a product of many factors. One such factor is broadly group into winter and spring annuals. Similar to the timing of the transition from vegetative to reproductive what has been discovered in wheat and barley, we find that growth. The switch to flowering causes a diversion of a portion of the phenotypic variation is associated with resources from the continual production of photosynthetic changes in expression of orthologs of VRN genes, and thus, material (leaves) to the terminal production of reproductive VRN genes are a possible target for modifying flowering tissue (flowers, seeds, and fruit).

No. 78 May 2008 Hairgrass (Vulpia Spp.). What Do We Know? a Review of the Literature
WEEDS, PESTS & DISEASES No. 78 May 2008 Hairgrass (Vulpia spp.). What do we know? A review of the literature. Key Points • In New Zealand the common name ‘hairgrass’ combines three individual Vulpia species (Vulpia bromoides, V. myuros and V. Megalura). • The individual species are very difficult to identify, with the seed head being the easiest feature to separate the species. • Typically germination follows a 2-3 month dormancy which breaks when monthly rainfall exceeds evaporation. • Germination occurs both in light and dark conditions; however germination is more rapid and uniform in the light. • Seedling emergence from the relatively shallow depth of 5cm is considerably less than 0-1 cm. • An integrated approach including cultivation, chemical and crop rotation is required for sustained control of Vulpia spp. • The relationship between burial through cultivation on seed dormancy and viability is not clear and will be the focus of future FAR funded research. • Chemical control can be difficult and will continue to be a focus of FAR trial work. Introduction Vulpia spp. has been increasingly common on Vulpia spp. are a problem in New Zealand in small arable farms in Canterbury in recent years. seed crops as they contaminate seed and reduce seed yield. As part of understanding annual grass weeds in Climate cropping rotations, a literature review on Vulpia Vulpia species can survive and reproduce over a hairgrass was undertaken. The aim of this review was wide range of climatic conditions; however to identify gaps in the knowledge which could allow Mediterranean type climates appear most FAR to establish research priorities.

Perennial Ryegrass Lolium Perenne L. Tom Cook OSU Horticulture Dept
Perennial ryegrass Lolium perenne L. Tom Cook OSU Horticulture Dept. Introduction: The first turf-type perennial ryegrasses were released in the USA in the early 1960’s. Since that time it has become the most widely planted turfgrass in all of western Oregon, western Washington, and the lower portion of western British Columbia in Canada. It is also used extensively in the interior portions of the Pacific Northwest. From home lawns to athletic fields to golf course tees, fairways, and rough areas this is an important grass for all turf managers. This guide will cover botany, history, cultural requirements, and strengths and weaknesses of this fascinating grass. Botanical Characteristics and Identification: Perennial ryegrass is a cool season (C-3 metabolism) perennial bunchgrass best adapted to mild climate areas. As a bunchgrass, it produces only tillers and has limited ability to spread. Turf type perennial ryegrass has a diploid chromosome count of 14. Forage types are either 14 (diploid) or 28 (tetraploid). It has an annual root system, meaning the majority of its roots are replaced annually during the spring flush growth period. Vernation: New leaves are distinctly folded as they emerge from surrounding leaf sheathes as opposed to annual ryegrass, which has rolled vernation. Young leaf folded in shoot Leaf tips: Leaf tips are intermediate between pointed and distinct boat shaped tips typical of the bluegrasses. I refer to them as speedboats, but I normally don’t bother with this characteristic. Speedboat Leaf tip Leaf morphology: The upper surface (adaxial) is distinctly ridged. These can be seen easily with the naked eye.

SUMMER SPOILERS of 2010 It’S Been a Challenging Summer for Lawns & Athletic Fields Pamela J
SUMMER SPOILERS OF 2010 It’s been a Challenging Summer for Lawns & Athletic fields Pamela J. Sherratt, David S. Gardner, John R. Street, T. Karl Dannerberger, Joseph Rimelspach, and David Shetlar. 2010 has been a particularly hot and brutal year for turfgrass managers in the Midwest. Lawns and athletic fields have been inundated with weeds and many have lost grass cover due to excessive heat and stress. The following article has been produced by the turfgrass science team at The Ohio State University to address some of these issues. THE EFFECTS OF HOT WEATHER ON COOL-SEASON TURF Cool-season turfgrasses prefer to grow in air temperatures between 60-75 degrees F and soil temperatures between 50 and 65 degrees F. While it is not uncommon for temperatures in Ohio to exceed these limits each summer, 2010 has been particularly challenging. A summary of air temperatures for both 2009 and 2010 can be seen in Table 1. In addition, it is important to note that the average soil temperature this year, at the 2” depth, was consistently above 70, increasing to a consistent 80 degrees by the end of June right through to August. By Comparison, in 2009, soil temperatures were above 70 by mid-June into July, and only got slightly above 80 in August. The higher day and night-time temperatures relative to most years resulted in significant stress on both the shoots and root system of all our typical cool- season grasses like Kentucky bluegrass, perennial ryegrass, fine fescue and bentgrass. Most people forget that the underground root system of turfgrasses is the key for absorbing nutrients and water.

New sequence data from representatives of the almost unexplored New World, New Zealand, and Eastern Asian centres were added to those of the panMediterranean region and used to reconstruct the phylogeny of the group and to calculate the times of lineage- splitting using Bayesian approaches. The traditional separation between broad-leaved and fine-leaved Festuca species was still main- tained, though several new broad-leaved lineages fell within the fine-leaved clade or were placed in an unsupported intermediate position. A strong biogeographical signal was detected for several Asian-American, American, Neozeylandic, and Macaronesian clades with dif- ferent aifinities to both the broad and the fine-leaved Festuca. Bayesian estimates of divergence and dispersal-vicariance analyses indicate that the broad-leaved and fine-leaved Loliinae likely originated in the Miocene (13 My) in the panMediterranean-SW Asian region and then expanded towards C and E Asia from where they colonized the New World.
