In addition, Genetic resistance to stem rust (caused by Puccinia graminis several cultivars of perennial ryegrass (Lolium perenne Pers.:Pers. subsp. graminicola Z. Urban) could reduce the need for fungicides to control the disease in tall fescue [Lolium arundinaceum L.) with reduced susceptibility to ste...

the performance of new forage brassica plants were studied in ilam, iran, during 2012-2014 in a field experiment using a randomized complete block design with four replications. the treatments included, different forage crops perko, buko, oilseed radish, berseem clover, and the combination of three plants ramtil, phaselia, and clover. the studied traits consisted of plant height, forage yield, ...

Perennial ryegrass (Lolium perenne L.) is a widely used cool-season grass species as turf and forage. In order to use biotechnological approaches to improve the species, factors affecting tissue culture responses of mature caryopses of perennial ryegrass were studied. Callus induction and regeneration from mature caryopses of thirteen recentlyreleased turf-type perennial ryegrass cultivars were...

The nutritional needs of bees are receiving renewed attention in the context of declining bee populations and changes in land use that threaten floral resources. We present a comprehensive analysis of the nutritional composition of sunflower (Helianthus annuus) pollen, comparing hand-collected, bee-collected and stored pollen. As found in previous studies, the protein content of sunflower polle...

The second occurs in late spring and early summer (May to June) when wheat has ceased growth and warm-seaThis study was conducted to determine seasonal forage production son pastures are not yet available for grazing (Northup, and nutritive value of the cool-season annual legumes grasspea (Lath2003). New plant species that can fill these gaps with yrus sativus L. cv. AC-Greenfix) and lentil (Le...

Little information is available comparing wheat forage varieties, rumen fermentation and biomass production for different wheat (Triticum aestivum L.) cultivars. A combination of grazing and in vitro experiments was conducted at Texas A & M (TAM) AgriLife Research and Extension Center, Vernon, TX from 2003 to 2004. Our objective was to determine the effects of wheat varieties (WV) and forage al...

Elephantgrass (Pennisetum purpureum Schum.) is native to regions of tropical Africa and was introduced in Brazil around 1920 through plantings imported from Cuba. It is currently one of the most widespread forage plants throughout the country. At first, there were two cultivars, Napier and Mercker, with well defined characteristics. New genotypes arose and it is believed that the large number o...

ball et al., 1997). The ecology of natural populations of plantain and its biology as a weed have been investigated Graziers in the northeast USA often face forage shortages in mid(Bassett, 1973; Kuiper and Bos, 1992). Apart from older summer. Chicory (Cichorium intybus L.) and English plantain (Plantago lanceolata L.) have been introduced in the USA as sumer-active reports in the scientific li...
