The genus Dactylis, an important forage crop, has a wide geographical distribution in temperate regions. While this genus is thought to include a single species, Dactylis glomerata, this species encompasses many subspecies whose relationships have not been fully characterized. In this study, the genetic diversity and phylogenetic relationships of nine representative Dactylis subspecies were exa...

BACKGROUND AND AIMS Current agricultural practices are based on growing monocultures or binary mixtures over large areas, with a resultant impoverishing effect on biodiversity at several trophic levels. The effects of increasing the biodiversity of a sward mixture on dry matter yield and unsown species invasion were studied. METHODS A field experiment involving four grassland species [two gra...

Microbacterium foliorum strain 122 is a bacterial endophyte isolated from a Dactylis glomerata plant growing in a natural oil seep soil located in Oil Springs, Ontario, Canada. We present here a draft genome sequence of an endophytic strain that has promising potential in hydrocarbon degradation and plant growth promotion.

علف باغ (dactylis glomerata) یکی از  گندمیان مهم مرتعی چند ساله برای ایجاد چراگاه و تولید علوفه خشک است. به منظور بررسی تنوع ژنتیکی جمعیتهای وحشی علف باغ و بررسی ارتباط عوامل اکولوژیکی  با تنوع پروتئینهای کل 11 جمعیت موجود در بانک ژن منابع طبیعی انتخاب شدند. در این تحقیق الگوی پروتئینی 110 ژنوتیپ از 11 جمعیت برای تعیین میزان تنوع ژنتیکی موجود مورد بررسی قرار گرفت. بر اساس نتایج sds-page، 25 نوا...

The effect of traffic on the content of lead and cadmium in grass morphological parts-leaves, shoots, and inflorescences-was studied. The samples were taken on a part of the European route E30 (Siedlce by road). The following plants were tested: Dactylis glomerata, Arrhenatherum elatius, and Alopecurus pratensis. During the flowering of grasses, the plant material was collected at distances of ...

Tillering is defined as the process of above-ground shoot production by a single plant. The number of grass tillers is one of the most important parameters in ecology and breeding studies. The number of tillers is usually determined by manually counting the separated shoots from a single plant. Unfortunately, this method is too time-consuming. In this study, a new method for counting grass till...

An understanding of the climate conditions governing spatial variation in the reproductive performance of plants can provide important information about the factors characterizing plant community structure, especially in the context of climate change. This study focuses on the effect of climate on the sexual reproductive output of Dactylis glomerata L., a perennial grass species widely distribu...
