Corn’s genetic diversity on display in new genome study
corn’s genetic diversity crop yields genetic diversity
2021/8/6
A new study details the genomes of 26 lines of corn from across the globe. The genomes can help scientists piece together the puzzle of corn genetics. Using these new genomes as references, plant scie...
Corn -- or maize -- has changed over thousands of years from a weedy plant that made ears with less than a dozen kernels to the cobs packed with the hundreds of juicy kernels we have today.Powerful DN...
NSF-funded scientists at Cold Spring Harbor Laboratory are figuring out how to pack more kernels onto a corn cob. One way to boost the productivity of a plant, they say, is to redirect some of its res...
Researchers Find Corn Gene Conferring Resistance to Multiple Plant Leaf Diseases（图）
Researchers Corn Gene Resistance to Multiple Plant Leaf Diseases
2017/9/1
Alleles that confer multiple disease resistance are valuable in crop improvement though molecular mechanisms underlying their functions remain largely unknown. A quantitative trait locus, qMdr9.02, as...
Corn is grown not only for food, it is also an important renewable energy source. Renewable biofuels can come with hidden economic and environmental issues, and the question of whether corn is better ...
Corn is grown not only for food; it is also used as an important renewable energy source. But renewable biofuels can come with hidden economic and environmental issues.The question of whether corn is ...
Natural parasitism of the second generation European corn borer eggs Ostrinia nubilalis (Hübner) (Lepidoptera, Pyralidae) by Trichogramma spp. in sweet corn fields in Vojvodina, Serbia – short communication.
O. nubilalis Trichogramma evanescens egg parasitoids sweet maize
2017/4/6
Natural parasitism of the European corn borer eggs (Hübner) by Trichogramma spp. (Hymenoptera, Trichogrammatidae) was assessed in sweet corn field in north-west Serbia, region Vojvodina at the localit...
Boosts in productivity of corn and other crops modify Northern Hemisphere carbon dioxide cycle（图）
productivity of corn Northern Hemisphere carbon dioxide cycle
2014/12/1
Each year in the Northern Hemisphere, levels of atmospheric carbon dioxide drop in the summer as plants "inhale," then climb again as they exhale after the growing season.
In 2020, NCGA will remain the preeminent voice representing the needs of the nation’s corn growers. We will maximize opportunities for the corn industry to meet growing domestic and global market dema...
Spatial variation of carbon dioxide fluxes in corn and soybean fields
Spatial Variation Transects Soil Organic Matter
2013/3/4
Spatial variation of soil carbon dioxide (CO2) flux during a growing season within corn and soybean canopies has not been quantified. These cropping systems are the most intense in the United States a...
Relationship of late-season ear leaf nitrogen with early- to mid-season plant height of corn
Corn Ear Leaf N Plant Height Relationship Models Cropping Systems
2013/2/28
Nitrogen concentration in the ear leaf is a good indicator of corn (Zea mays L.) N nutrition status during late growing season. This study was done to examine the relationship of late-season ear leaf ...
Preparation and mechanism analyses of a new corn seed coating agent
Coating Germination Rate Inhibitory Rate Antifeedant Rate
2013/3/5
Due to the severity of the disease and yield losses of corn, this study had achieved a novel corn seed coating agent which was prepared with polysaccharide, fertilizer, microelement and other assistan...
The effects of different autumn-seeded cover crops on subsequent irrigated corn response to nitrogen fertilizer
Corn Cover Crop Nitrogen Fertilizer
2013/3/5
A common crop rotation in the west Iran is wheat-fallow-corn. The fallow period after wheat harvest (during fall and winter) can lead to soil erosion, nutrient losses (e.g. nitrate leaching) and offsi...
Soybean seed protein, oil, fatty acids, and mineral composition as influenced by soybean-corn rotation
Fatty Acids Mineral Nutrients Oil Protein Seed Composition Soybean-Corn Rotation
2013/3/5
Effects of crop rotation on soybean (Glycine max (L) Merr.) seed composition have not been well investigated. Therefore, the objective of this study was to investigate the effects of soybean-corn (Zea...
Evaluation of drought tolerance of some corn (Zea mays L.) hybrids in Iran
Corn drought resistance indices hybrid cluster analysis
2011/1/12
The effect of drought stress on yield and its components was studied on 28 new hybrids of maize along with 6 commercial control hybrids at the Khorasan Razavi Agricultural Research and Natural Resourc...
