Bromus
''Bromus'' is a large genus of grasses, classified in its own tribe Bromeae. They are commonly known as bromes, brome grasses, cheat grasses, or chess grasses. Estimates in the scientific literature of the number of species have ranged from 100 to 400, but plant taxonomists currently recognize around 160–170 species. ''Bromus'' is part of the cool-season grass lineage (subfamily Pooideae), which includes about 3300 species. Within Pooideae, ''Bromus'' is classified in tribe Bromeae (it is the only genus in the tribe). ''Bromus'' is closely related to the wheat-grass lineage (tribe Triticeae) that includes such economically important genera as ''Triticum'' (wheat), ''Hordeum'' (barley) and ''Secale'' (rye). Etymology The generic name ''Bromus'' is derived from the Latin ''bromos'', a borrowed word from the Ancient Greek (). and mean ''oats'', but seems to have referred specifically to '' Avena sativa'' (Hippocrates ''On Regimen in Acute Diseases'' 2.43, Dioscorides Me ...

Bromus Diandrus
''Bromus diandrus'' is a species of Poaceae, grass known by the common names great brome and "ripgut brome". Description This is a Bromus, brome grass which is native to the Mediterranean Basin, Mediterranean but has been introduced species, introduced to much of the rest of the world. It does best in areas with a Mediterranean climate, such as California and parts of southern Australia, but it is quite tolerant of many climates. Ripgut brome is a winter annual that grows throughout winter and spring and matures in the summer. The adult plant is one to three feet in height with hairy, rough leaves about a centimeter wide. The membranous ligule is prominent, white with spiky hairs. The wide panicle nods like that of an Avena, oat plant, and it bears a large, splayed spikelet with a very long Awn (botany), awn which can exceed five centimeters in length. The seeds easily break out of the spikelet. They are very sharp and very rough due to tiny barb-like hairs that face backward, al ...

Bromus Rigidus
''Bromus rigidus'', the ripgut brome, is a grass native to Eurasia and naturalized in North America. The specific epithet ''rigidus'' means rigid or stiff. Description ''Bromus rigidus'' is an annual grass growing tall. The culms, leaves, and panicle branches are all pubescent or harsh. The erect or ascending panicle has short branches that terminate in four to nine flowered spikelets. The reddish spikelets are long, including the awns measuring long. The first glume has one nerve and the second has three. The lance-attenuate lemmas are unequal, with the lower having a long tooth on each side of the awn and the upper tapering to the beak. The scabrous lemmas are strongly ciliate. The anthers are approximately long. The common name "ripgut brome" refers to the heavy sclerotization of the species, creating a hazard to livestock. The seeds of the plant can penetrate the skin of livestock and the callus and awns can penetrate the mouth, eyes, and intestines of livestock. ''B ...

Sclerenchyma
The ground tissue of plants includes all tissues that are neither dermal nor vascular. It can be divided into three types based on the nature of the cell walls. This tissue system is present between the dermal tissue and forms the main bulk of the plant body. # Parenchyma cells have thin primary walls and usually remain alive after they become mature. Parenchyma forms the "filler" tissue in the soft parts of plants, and is usually present in cortex, pericycle, pith, and medullary rays in primary stem and root. # Collenchyma cells have thin primary walls with some areas of secondary thickening. Collenchyma provides extra mechanical and structural support, particularly in regions of new growth. # Sclerenchyma cells have thick lignified secondary walls and often die when mature. Sclerenchyma provides the main structural support to the plant. #Aerenchyma cells are found in aquatic plants. They are also known to be parenchyma cells with large air cavities surrounded by irregular c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Livestock
Livestock are the Domestication, domesticated animals that are raised in an Agriculture, agricultural setting to provide labour and produce diversified products for consumption such as meat, Egg as food, eggs, milk, fur, leather, and wool. The term is sometimes used to refer solely to animals which are raised for consumption, and sometimes used to refer solely to farmed ruminants, such as cattle, sheep, and goats. The breeding, maintenance, slaughter and general subjugation of livestock called ''animal husbandry'', is a part of modern agriculture and has been practiced in many cultures since humanity's transition to farming from hunter-gatherer lifestyles. Animal husbandry practices have varied widely across cultures and periods. It continues to play a major economic and cultural role in numerous communities. Livestock farming practices have largely shifted to intensive animal farming. Intensive animal farming increases the yield of the various commercial outputs, but also nega ...
