Abstract:
... Application of growth promoters or inhibitors and mowing height adjustment are potential means of improving the growth and performance of TifEagle bermudagrass [Cynodon dactylon (L.) Pers. x C. transvaalensis Burtt-Davy] in a reduced light environment (RLE). A study was conducted in June to August 2001 and 2002 to examine the effects of growth factors and two mowing heights on TifEagle bermudagras ...

Glycine max; alleles; crossing; high-yielding varieties; homozygosity; lodging; metabolizable energy; oils; oleic acid; palmitates; raffinose; seed characteristics; seed yield; soybean meal; soybeans; stachyose; stearic acid; sucrose; Iowa
Abstract:
... Monogastric animals cannot readily digest the raffinose and stachyose in soybean [Glycine max (L.) Merr.], which reduces the amount of metabolizable energy that can be obtained from soybean meal. Soybean cultivars homozygous for the recessive allele stc1a from PI200508 have a reduced content of raffinose and stachyose and an increased content of sucrose. The objective of our study was to evaluate ...

Abstract:
... About 75% of the total P in conventional soybean [Glycine max (L.) Merr.] seed is phytate P, which cannot be readily digested by nonruminant livestock, such as swine and poultry. The phytate P in soybean lines homozygous for the recessive alleles pha1 and pha2 is reduced to about 25% of the total P. The objective of this study was to determine the influence of low phytate (LP) on agronomic and see ...

Abstract:
... Optimizing biofuel production and quality from switchgrass (Panicum virgatum L.) may require matching of ecotype and morphological type to environments, particularly in southern regions. Nine genotypes from four combinations of ecotype and morphological switchgrass type were harvested from 1998 to 2000 in five sites across Texas, Arkansas, and Louisiana that varied in latitude and precipitation. A ...

CWG-R is an experimental population of crested wheatgrass [Agropyron cristatum (L.) Gaertn.] from Iran that has shown potential as a low-maintenance turf. The objective of this research was to estimate the ...

Abstract:
... The fungal endophyte Neotyphodium coenophialum Morgan-Jones and Gams is abundant in tall fescue (Festuca arundinacea Schreb.) and one strategy to alleviate detrimental effects on livestock is to plant endophyte-free cultivars; however, these pastures frequently become recontaminated by toxic-endophyte tall fescue. An alternative strategy is to use pastures of tall fescue infected with endophyte th ...

Abstract:
... Bermudagrasses (Cynodon spp.) are important for turf and forage in temperate and tropical climates, with cultivars historically propagated clonally. Over the past two decades the number of seed-propagated commercial cultivars has dramatically increased, but information is lacking on the extent of the genetic diversity among these new cultivars. Accordingly, this research was undertaken to assess t ...
