Effect of altered leaf angle on maize stalk lodging resistance [PDF]

Crop Science, 2020
AbstractIncreasing light intensity in the mid and low canopy can improve maize (Zea mays L.) stalk lodging resistance. Field experiments involving altered leaf angle were designed to explore how leaf angle affects the light distribution within the canopy, stalk carbohydrate accumulation, stalk strength formation, and grain yield. When the leaf area was

Physiological Influence of Stalk Rot on Maize Lodging after Physiological Maturity

Agronomy, 2021
The stalk lodging caused by stalk rot after physiological maturity (PM) is a major factor restricting further development of mechanical grain harvesting in China. The physiological mechanism of stalk rot on maize stalk lodging after PM is not clear. This

Sex-Related Color Patterns in Elytral Vittae of \u3ci\u3eDiabrotica Virgifera Virgifera\u3c/i\u3e (Coleoptera: Chrysomelidae) [PDF]

, 2017
We evaluated the color patterns of elytral vittae by sex in adults of Diabrotica virgifera virgifera leConte. Our study examined \u3e1000 beetles taken from a field population, a laboratory colony, and a reference collection containing 712 specimens from

Effects of Plant Growth Regulators and Nitrogen Management on Root Lodging Resistance and Grain Yield under High-Density Maize Crops

Agronomy, 2022
Lodging is one of the main factors causing yield loss of maize under high-density planting conditions. Root lodging as an important lodging type has received little attention.

Maize Stalk Lodging: Morphological Determinants of Stalk Strength

Crop Science, 2017
An incomplete understanding of stalk strength and stalk lodging impedes efforts to improve maize (Zea mays L.) production. To develop a more complete understanding of stalk strength, the current study examined the effect of stalk morphology on stalk bending strength.

Maize Stalk Lodging: Flexural Stiffness Predicts Strength

Crop Science, 2016
Late‐season stalk lodging in maize (Zea mays L.) is a major agronomic problem that has far‐reaching economic ramifications. More rapid advances in lodging resistance could be achieved through development of selective breeding tools that are not confounded by environmental factors.

Keratin 19 as a prognostic marker and contributing factor of metastasis and chemoresistance in high‐grade serous ovarian cancer

Molecular Oncology, EarlyView.
Keratin 19 (KRT19) is overexpressed in high‐grade serous ovarian cancer with high levels of Kallikrein‐related peptidases (KLK) 4–7 and is associated with poor survival. In vivo analyses demonstrate that elevated KRT19 increases peritoneal tumour burden.

Spraying Ethephon Effectively Increased Canopy Light Transmittance of Densely Planted Summer Maize, Thus Achieving Synergistic Improvement in Stalk Lodging Resistance and Grain Yield

Plants, 2022
Increasing planting density is an effective way to improve maize yield, but high plant populations often cause a lodging problem. This experiment was conducted to investigate the effect of increasing planting density on stalk lodging resistance and grain
