Whole-genome sequences established for model and major crop species constitute a key resource for advanced genomic research. For outbreeding forage and turf grass species like ryegrasses (Lolium spp.), such resources have yet to be developed. Here, we present a model of the perennial ryegrass (Lolium perenne) genome on the basis of conserved synteny to barley (Hordeum vulgare) and the model gra...

The number of egg rafts oviposited by Culex pipiens and Culex restuans in infusion-baited ovitraps varied with the type of infusion substrate, infusion age, method of infusion preparation, and calendar date. In one or more tests, more Culex egg rafts were collected from water infused with Kentucky bluegrass sod, mixed grass clippings, straw, or a commercial rabbit chow than from a water control...

Weeds are commonly found in bermudagrass turf during the winter and early spring throughout the Southeastern United States whether this turf is used for lawns, parks, athletic fields or golf courses. Mild winter temperatures favor rapid growth of these annuals. When bermudagrass goes dormant in the fall after the first killing frost, it does not compete with germinating winter weeds. Bermudagra...

The grass family Poaceae includes annual species cultivated as major grain crops and perennial species cultivated as forage or turf grasses. Heat stress is a primary factor limiting growth and productivity of cool-season grass species and is becoming a more significant problem in the context of global warming. Plants have developed various mechanisms in heat-stress adaptation, including changes...

The market for turf-type perennial ryegrass (Lolium perenne) continues to grow with over $70 million in seed sales in 1994. Breeders in private companies are capitalizing on this increasing ryegrass popularity by continuing to make improvements in turf quality traits such as color, density, texture, mowability and disease resistance. However, all current improved turf-type cultivars do not have...

Synthetic turf is a manufactured product that utilizes synthetic fibers mimic the aesthetic look of natural grass. While designed to imitate turf, does not provide ecosystem benefits system. This publication examines properties in relation each FFL’s nine principles. A new UF/IFAS Environmental Horticulture Department; 4 pages.https://edis.ifas.ufl.edu/ep612

The shoe-surface interface has been implicated as a possible risk factor for anterior cruciate ligament (ACL) injuries. The purpose of this study is to develop a biomechanical, cadaveric model to evaluate the effect of various shoe-surface interfaces on ACL strain. There will be a significant difference in ACL strain between different shoe-surface combinations when a standardized rotational mom...
