This essay considers annuality and perenniality as quantitative traits and discusses the application of established and new genetic tools to the analysis of plant life histories. Annual/perennial status is a function of meristem determinacy in combination with the processes of cell death and disposal employed by plants to generate well-adapted anatomies and morphologies. Creeping perennials, li...

The effects of soil drenches with systemic fungicides on viability of clavicipitaceous anamorphic endophytes, non-choke inducing endosymbiotic fungi of the genus Neotyphodium that systemically infect grasses, were tested in endophyte-infected seedlings of Hordeum brevisubulatum subsp. violaceum, Lolium perenne and Festuca arundinacea germplasm. None of the endophytes of these grasses were sensi...

The chinch bug, Blissus occiduus Barber (Hemiptera: Blissidae), is an important pest of buffalograss, Buchloë dactyloides (Nutall) Engelmann and potentially other turfgrass, crop, and non-crop hosts. Choice studies documented the number of B. occiduus present on selected turfgrasses, crops and weeds, and provided important insights into the host preferences of this chinch bug. Grasses with the ...

Drought tolerant plant genotypes are able to maintain stability and integrity of cellular membranes in unfavorable conditions, and to regenerate damaged membranes after stress cessation. The profiling of cellular glycerolipids during drought stress performed on model species such as Arabidopsis thaliana does not fully cover the picture of lipidome in monocots, including grasses. Herein, two clo...

Turfgrass stakeholder surveys have indicated fine fescue (Festuca spp.) seed will become in higher demand, but production the U.S., especially Oregon, has not increased. Northern Minnesota is conducive for cool-season turfgrass and existing infrastructure to produce seed. There an exciting opportunity northern Minnesotan farmers increase revenue by producing seed; however, fescues require a gro...

This research was conducted in the field of Malta nursery/Dohuk governorate- Iraq, for period 12/15/2021 to 5/15/2022. It aims study effect irrigation numbers and urea fertilizer levels on growth performance evergreen thyme fodder turf grass seeds mixture consist (21% Poa Pratensis, 39% Festuca rubra 40% Lolium perenne). focused two main factors, first is includes (once time week, twice times w...

A study of the leaf anatomy in the species of the genus Festuca present in the Iberian Peninsula was made. A total of 68 taxa were included and 15 characters were measured in leaf cross-section. The major anatomical features of each taxonomic group were characterized, and some variability was observed in the taxa. The anatomical patterns observed were compared and discussed with the relationshi...
