WebFurther studies should be focused on improving the understanding of the changes over time in yield components at varying crowding stress levels. Overall, plant density contributed to 9-18% of the corn yield gain during the last 30 years of crop improvement. WebOct 29, 2024 · Furthermore, heat stress during grain filling decreases the activities of sucrose phosphate synthase (SPS) and sucrose synthase (SuSy), resulting in decreased sucrose content; consequently,...
WebJul 1, 2006 · Effects of spacing and emergence variability on maize grain yield are the net result of the responses of all plants within the stand. The objective of this study was to quantify effects of spacing and emergence variability on crop yield in terms of increased or decreased crowding stress on resource capture (i.e., dry matter accumulation) and ...
WebMay 1, 2005 · The main objective of this research was to quantify the sensitivity of grain yield and its components to manipulation of crowding stress in corn (Zea mays L.). The experiment was conducted in Deerfield, MA (1986, 1987, and 2000), and Shoush, Iran … WebSep 26, 2024 · The major genetic contribution to the increase in yield has been to increased “crowding stress” tolerance [ 5 ]. This tolerance has resulted in increased grain yield through planting higher corn plant populations.
WebSep 22, 2024 · Choe et al. (2016) reported that the molecular basis of crowding stress tolerance in sweet corn is genotype specific, i.e., PDT hybrids have unique …
Webthe country the third largest global corn producer and the second largest corn exporter. Brazil has emerged as the largest U.S. competitor in the global corn market with second-crop corn, harvested late in the local marketing year, boosting exports from September to January, months traditionally dominated by Northern Hemisphere exporters. do bettas eat baby snailsWebThe average U.S. plant population continues to increase as U.S. growers continue to push corn (Zea mays L.) grain yields higher. However, this increased plant population typically … creating bar graph in excel with dataWebAs this trend continues, the average U.S. corn seeding rate will reach 38,000 seeds/A in 15 years and 44,000 seeds/A in 30 years. These higher seeding rates reduce the plant-to-plant spacing within the row and the intensifying crowding stress may become yield-limiting. do bettas have to have a heaterWebJan 21, 2016 · Under conditions of crowding stress, three high-yielding and three low-yielding sweet corn hybrids were grouped for transcriptional and phenotypic analyses.
