Effects of light intensity within the canopy on maize lodging

Field Crops Research, 2016
Abstract Close planting often increases the lodging rate of maize, but the cause is unclear. Close planting reduces light intensity within the canopy; therefore, we hypothesized that light intensity may be the main factor affecting maize lodging. To test this hypothesis, three field experiments involving plant density, shading and defoliation were ...

Lodging resistance in maize: A function of root–shoot interactions

European Journal of Agronomy, 2022
Abstract The differences in root and stem structure between lodging resistant (LR) and susceptible (LS) genotypes have yet to be fully understood in maize (Zea mays L.). To clarify these differences, lodging rates and yield of LS genotype XunDan20 (XD20) and LR genotype FuMin985 (FM985) across five locations in China from 2014 to 2018 were ...

A biomechanical model for maize root lodging

Plant and Soil, 2017
Root lodging is a structural failure of the root-soil anchorage system in a plant that adversely affects its yield. It is a complex phenomenon that depends strongly on both crop genetics and environmental factors. An accurate biomechanical model to predict root lodging would disentangle the component factors and improve development of lodging resistant

Cryptochrome 1b represses gibberellin signaling to enhance lodging resistance in maize

Plant Physiology, 2023
Abstract Maize (Zea mays L.) is one of the most important crops worldwide. Photoperiod, light quality, and light intensity in the environment can affect the growth, development, yield, and quality of maize. In Arabidopsis (Arabidopsis thaliana), cryptochromes are blue-light receptors that mediate the photocontrol of stem elongation, leaf

Effects of Defoliation on Lodging and Yield of Maize Hybrids

Experimental Agriculture, 1979
SUMMARYReducing the leaf areas of different maize hybrids at the time of female flowering resulted in a reduction of up to 70–90 g/plant of grain yield, with a parallel deterioration in the health of the stalk pith (due to infection by Fusarium sp.) and an increase in lodging.

Root Morphology of Maize and Its Relationship to Root Lodging

Journal of Agronomy and Crop Science, 1992
AbstractCrown root traits of maize (Zea mays L.) such as number and diameter are the most easily accessible root traits. Their impact on root lodging resistance is little documented. We evaluated 28 flint x dent hybrids at one location for 2 years for crown root traits and for lengths of internodes.

Defoliation at seedling stage enhances maize yield by reducing lodging

Agronomy Journal, 2023
AbstractLodging greatly reduces maize (Zea mays L.) grain yield and harvest efficiency. We conducted a 3‐year (2018–2020) field experiment in Fengcheng city, Liaoning, China to investigate the effects of maize seedling defoliation on lodging resistance and grain yield.
