Carbon cycling is a highly complex yet critical process, especially in silvopastures, which have multiple pools with the ability to store large amounts of C. However, it largely unknown how site-specific variables, including edaphic factors, vegetation type, topography, and management, affect soil CO2 flux silvopastures. Therefore, this study aimed evaluate fluxes silvopastoral system as affect...

Southern crabgrass (Digitaria ciliaris [Retz.] Koel.) is often viewed as an undesirable weed, largely because it encroaches upon field and forage crops, gardens, and lawns. However, visual observations of livestock grazing mixed-species pastures suggest that cattle seem to prefer crabgrass to many other summer forages. The objectives of this study were to assess the nutritive value of crabgrass...

The uti l ization of minerals in orchardgrass (Dactylis glomerata L.) fertilized with kieserite (2,240 kg/ha) was examined in spring with lactating beef cows and wether lambs. Kieserite increased the concentration of Mg in vegetative herbage from .22 to .29% (P<.01) and of S from .20 to .29% (P<.01), with little effect on other minerals. Fert i l ization also increased (P<.01) apparent absorpti...

Abstract Choke disease, which is caused by Epichloë typhina , was first reported in orchardgrass seed production fields the Willamette Valley, Oregon 1997 and has continued to persist system. The disease can cause up 30% losses yield. Unlike many species that are transmitted, it unclear how infection of E. occurs field, or spreads within plants. In this study, overall incidence choke on trap pl...

Plant regeneration capacity of orchardgrass leaf explants cultured in vitro in the presence of 0.01, 0.1, 1.0 and 10.0mM hydroxyproline (Hyp) or azetidin-2-carboxylic acid (A2CA) was determined. Hyp inhibited to a lower extent than A2CA formation of somatic embryos, respectively plants. Hyp also induced relatively insignificant changes of free amino acid content in the leaves of the regenerants...

Orchardgrass, or cocksfoot, is an important perennial forage grass worldwide. The comprehensive understanding of orchardgrass accessions will benefit germplasm collection and breeding progress, and it will enhance efforts to improve forage yield and quality. Therefore, 24 novel, simple, polymorphic, and reliable start codon-targeted (SCoT) markers were used to analyze the diversity and genetic ...
