Influence of Organic Matter Source, Abundance, and Growth Habit on Depositional Textures and Associated Pore Attributes of Hypersaline Lacustrine Microbial Deposits (Holocene, Bahamas)
… of organic matter source, abundance, and growth habit on Holocene microbialite fabrics. Integrated multi-scale analyses characterize fabrics of Holocene microbialites in a small, shallow, hypersaline, alkaline lake in the southern Bahamas. The results of analyses reveal: systematic …

Evaluation of Genomic Prediction and the Agronomic Performance of Facultative Barley
… barley typically exhibits either a winter growth habit or a spring growth habit. Some cultivars display a facultative growth habit, allowing them to be cultivated as either winter or spring crops. This study evaluated 1,128 elite barley cultivars and breeding lines under fall and spring …

The inheritance of four morphological traits in peanut (Arachis hypogaea L.)
… and to analyze genetic factors controlling growth habit, stem color, root nodulation, and leaflet size in peanut. F1 and F2 progenies were obtained from diallel crosses between A. hypogaea cvs. Argentine and T2442, and A. monticola. Fz progenies and parents were grown at the Tidewater …

Genetic diversity of the HvFT1 flowering gene in Nordic spring barley (Hordeum vulgare L.)
… sequence polymorphisms, flowering time data and growth habit demonstrated an association between the BGS213- and E40 (Voh2825) alleles and early flowering and spring growth habit. A similar association was discovered between the PE/IAG haplotype and early flowering as well as spring growth habit. …

Canopy Architecture and Plant Density Effect in Short-Season Chickpea (Cicer arietinum L.)
… chickpea canopy types, i.e., leaf type and growth habit, by investigating seed yield responses at 30 to 85 plants m-2 and ii) identify desirable parental traits for breeding programs by assessing growth and yield parameter responses to varying leaf types and growth habits at a range of …

A comparative analysis of the reproductive efficiency of 14 Virginia market type peanut cultivars (Arachis hypogaea L.)
… to hybridization followed by selection, and in growth habit from erect to spreading. The traits studied included flower total (FT), mature pod total (MPT), seed total (ST), pod total (PDT), peg total (PGT), immature pod total (IMPDT), mature pod dry weight (MPDW), plant dry weight (PLDW), vine …

Application of plant tissue and organ culture in soybean improvement for resistance to Septoria glycines
… on detached cotyledons and inhibited the growth of soybean callus. Less than 20% of the seeds germinated on culture filtrate-containing water-agar at a 1:2 dilution. Embryogenesis was stimulated when germinated soybean seeds on water-agar (6 g/l) containing 40 $\mu$M …

Crystallization behavior of poly (p-phenylene sulfide): kinetics and morphology
… of bulk crystallization, spherulitic radial growth rates, and nucleation densities were analyzed as functions of molecular weight of PPS, branching agent concentration, and chemical nature of the endgroup counter-atom. The overall rate of bulk crystallization was described by an Avrami …

Improvement of common bean (Phaseolus vulgaris L.) for regional food systems in the northeastern United States
… agronomic traits such as yield and upright growth habit into two heirloom varieties with unique seed coat phenotypes, using a marker-assisted selection model. The four targeted diseases were common bacterial blight, caused by Xanthamonas campestris pv. phaseoli, anthracnose, caused by …

Utilization of common buckwheat as a short-cycle cover crop before direct-seeded processing cucumber production
… (Cucumis sativus) production because of the growth habit of cucumber and its sensitivity to herbicides. One alternative method is utilizing short-cycle summer cover crops, such as common buckwheat (Fagopyrum esculentum) prior to planting cucumber. However, this needs to be tested to assess …

Phenotypic characterization of the Peach (Prunus spp.) collection at the National Clonal Germplasm Repository in Davis, California
… bred and cultivated. In peach, specific tree growth habits are used in breeding to select for tree architectures that may provide growers with more options for orchard design and cultural practices. The presence of extrafloral nectaries on leaf petioles has been found to confer beneficial …

Cotton Yield as Related to Selected Physical and Chemical Properties of Soils of the Coastal Plain of Virginia and North Carolina
… L) is a warm season perennial with indeterminant growth habit. In 1995, 42,500 and 300,000 hectares were grown in Virginia and North Carolina, respectively. Soil physical and chemical properties may limit cotton yields. The objective of this study was to; 1) determine influences of soil physical …
