Genetic Improvement of Switchgrass Cell Wall Content, Leaf Angle and Flowering Time
… efficiency for biofuel production. Erect leaf is a desirable trait to adjust the overall plant architecture to perceive more solar energy and thereby to increase the plant biomass production in a field population. We overexpressed an Arabidopsis NAC transcriptional factor gene, LONG …

The ecological significance of leaf movements in Rhododendron maximum
Although leaf movements have been documented for over a century, there are few studies focused on the adaptive significance of leaf movements, especially with experiments under controlled conditions. The major objective in this study is to determine the ecological significance of leaf movements in …

Agronomic and phenotypic responses to 75 years of recurrent selection for yield in the Iowa Stiff Stalk synthetic maize population
… test weight, stalk and root lodging, flag leaf angle, anthesis-silking interval(ASI), plant height, tassel branch number, and total number of leaves have been well characterized in comparisons of commercial hybrids representing different eras of hybrid maize production but have yet to be …

Effects of Morphological Traits and Cultural Practices of Intercropped Soybeans and Cereals
… (1) the effects of sorghum plant height, maize leaf angle, delayed planting of sorghum and maize, and row width on interrow-intercropped soybeans, and (2) the effect of nodulating and nonnodulating near-isolines of soybeans on intercropped sorghum. Three experiments were conducted to consider …

Quantitative genetic analysis of maize organogenesis
… serves both purposes. Maize tassel, ear, and leaf organogenesis, although divergent in position on the plant, are hypothesized to share many of the same regulating genomic components. Insights into the genes regulating leaf, ear, and tassel morphology have implications for our understanding of …

Surfactant Formulations to Enhance Triclopyr Amine Efficacy: Effects on Adhesion, Retention and Contact Phytotoxicity On Three Hardwood Species
… efficient wetting of even the most hydrophobic leaf surfaces. Additionally, by virtue of their low surface tension, these adjuvants can significantly increase the uptake of active chemicals directly into the plant via stomatal infiltration ( Stevens et al., 1991). Triclopyr …

Can plant survive without steroids: Modulation of plant architecture and sex determination through brassinosteroid biosynthesis and signaling
… including organ size, sex determination, and leaf angle. However, genetic mechanisms by which BRs regulate plant architecture traits in maize remain poorly understood. We have generated and characterized several brassinosteroid biosynthesis and signaling mutants that emphasize the role of BRs …

Yield Improvement in Eastern Soft Red Winter Wheat from 1919 to 2009
… Red May (1919) and; 2) to determine effects of leaf rust (Puccinia triticina f. sp. tritici) and powdery mildew [Blumeria graminis (DC.) E.O. Speer f. sp. tritici Em. Marchal] on grain yield components and agronomic traits. Replicated yield trials were grown at Warsaw, VA in 2010 and 2011, and …

Agronomic management to improve corn productivity under high-yielding environments
… were related to capturing more sunlight (leaf angle, leaf width, leaf length, and leaf area per plant), plant size (stover biomass per acre, total above-ground biomass per acre, and plant width), and root weight per plant. What is the Best Nitrogen Source, Placement, and Timing to Improve …
