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

Optimizing Row Spacing Increases Stalk Lodging Resistance by Improving Light Distribution in Dense Maize Populations

Agronomy, 2023
Dense planting effectively increases maize yield while increasing stalk lodging risk. Appropriate row spacing can improve the maize population structure and stalk lodging resistance, but its physiological ecological mechanisms and interaction with ...

Key indicators affecting maize stalk lodging resistance of different growth periods under different sowing dates

Journal of Integrative Agriculture, 2020
The accurate evaluation of maize stalk lodging resistance in different growth periods enables timely management of lodging risks and ensures stable and high maize yields. Here, we established five different sowing dates to create different conditions for

A Comparison of Maize Stalk Rot Occurrence in Bt and Non-Bt Hybrids [PDF]

, 2002
Stalk rots, caused by a complex of fungal species, are among the most widespread and destructive diseases of maize. Larvae of the European corn borer (ECB) (Ostrinia nubilalis) promote stalk rot development by creating entry points for fungi, serving as ...

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.

Effects of plant density and nitrogen rate on lodging-related stalk traits of summer maize

Plant, Soil and Environment, 2016
Stalk lodging is a major constraint to limit grain yield under increased planting density in modern maize (Zea mays L.) production. A 3-year field experiment was imposed to study the effects of plant density and nitrogen (N) rate on stalk lodging and ...

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.

Stalk Lodging: A Portable Device for Phenotyping Stalk Bending Strength of Maize and Sorghum [PDF]

, 2019
ABSTRACTBackgroundStalk lodging (breakage of plant stems prior to harvest) is a major problem for both farmers and plant breeders. A limiting factor in addressing this problem is the lack of a reliable method for phenotyping stalk strength. Previous methods of phenotyping stalk strength induce failure patterns different from those observed in natural ...

Stalk Bending Strength is Strongly Associated with Maize Stalk Lodging Incidence Across Multiple Environments

Field Crops Research, 2019
AbstractStalk lodging in maize results in substantial yield losses worldwide. These losses could be prevented through genetic improvement. However, breeding efforts and genetics studies are hindered by lack of a robust and economical phenotyping method for assessing stalk lodging resistance.

Field Based Phenotyping for Stalk Lodging Resistance: Experimental Error Analysis

, 2023
Abstract Background: Meeting the global demand for grain is becoming increasingly difficult due to numerous factors including climate variability, urbanization, increasingly frequent extreme weather events and drought. Stalk lodging destroys between 5%-25% of grain crops annually. Developing crop varieties with improved lodging resistance will
