Characterizing Low Nutrient Stress Resistance in Crop Sunflowers (Helianthus annus)
… associated with low nutrient stress resistance. Sunflowers were assessed for stress resistance using height, stem diameter, biomass, and root structure traits. Sunflowers responded to nutrient stress through a decrease in overall size and increased root width near the surface and steeper lateral …

The physiological effects of heat stress on anthesis and pollination in domesticated sunflowers (Helianthus annuus L.)
… heat waves affect anthesis and pollination in sunflowers (Helianthus Annuus L.). This study investigates the effect of heat stress on timing of pollen emergence, style elongation rate, pollinator visits, pollen viability and stigma receptivity. We sampled during the anthesis period in a field …

EFFECT OF PINCHING AND SPACING ON THE GROWTH AND DEVELOPMENT OF SUNFLOWERS (HELIANTHUS ANNUUS) IN EAST TEXAS
… produced marketable stems for ‘Vincent’s Choice’ sunflowers. Only the pinching treatment at node 1 failed to produce a marketable stem for ‘Sun Bright Supreme’ sunflowers whereas ‘Pro Cut Gold’ did not produce marketable stems when pinched at nodes 1 and 3. Only the pinching treatment at node 3 …

Pinching and Spacing Effects on Cut Sunflower (Helianthus annuus) Production in East Texas
… pinching nodes 1, 2, 3, or 4 on ‘Pro Cut Gold’ sunflowers. Results from experiment 1 showed non-pinched plants produced marketable stem lengths and flower sizes, while pinched plants’ stem length, stem diameter, flower diameter, and disk diameter decreased compared to the non-pinched plants. The …

Economic Analysis of Sunflower (Helianthus annuus) Spacing in East Texas
… the most profitable spacing of specialty cut sunflowers grown in East Texas is 8 × 15 cm. East Texas growers should consider the quality and quantity of desired crop to determine the proper spacing of specialty cut sunflowers.</p>

Alteration of Milk Composition in Dairy Cows Fed Supplemental Fat
… fatty acids from canola, soybeans, and sunflowers decreased intake of nutrients and milk production more than infusing long-chain fatty acids from a highly saturated (85%) fat and milk protein percentage was decreased to a similar extent. Infusing long-chain fatty acids from canola, …

Increased phenotypic plasticity linked to broader geographic range size in sunflower (Helianthus) species
… the growth and fitness of broadleaf species like sunflowers (Helianthus spp.). In a garden experiment, we compared the phenotypic plasticity of five Helianthus species representing different geographic ranges. Locally restricted H. longifolius and H. verticillatus showed less plasticity in growth …

Evaluation of Bioherbicidal Properties of Pseudomonas syringae pv. tagetis for Control of Canada thistle (Cirsium arvense)
… P. syringae pv. tagetis 6371 was 1x109 cfu/mL in sunflowers and similar in Canada thistle. Finally, it was found that strains 6370, 6371 and 6564 had some negative effects on plants in the family Brassicaceae in terms of chlorosis, reducing healthy tissue, and reducing leaf biomass of plants. …

Ecology of Gray Partridge in North Dakota
… partridge during winter were cereal grains, sunflowers, and farmstead/wooded areas. Differences in habitat use were noted among years, dates, and snow depth. Roadside observations of partridge habitat did not accurately reflect actual use by partridge during winter. Capturing and …

Effect of small grain residue and tillage method on the emergence and growth of sunflower (Helianthus annuus L.)
… barley straw on the germination and growth of sunflowers in controlled environments. Sunflower planted into tilled and no-tilled three week old wheat residue showed no differences in emergence from those planted into followed plots. Sunflower leaf numbers at four weeks were reduced in wheat …
