Maize (Zea mays L.) stem is thought to function alternately as a net importing and net exporting organ during ontogeny, depending on whole plant photosynthetic source and sink status. The [(14)C]sucrose and [(14)C]glucose uptake capacity of stem tissues was investigated to increase our understanding of the transport factors which may influence sink status.Uptake from solutions containing up to ...

UV-B radiation effects on nutrient concentrations in above-ground organs of maize were investigated at silking and maturity at different levels of applied nitrogen under field conditions. The experiment simulated a 20% stratospheric ozone depletion over Portugal. At silking, UV-B increased N, K, Ca, and Zn concentrations, whereas at maturity Ca, Mg, Zn, and Cu increased and N, P and Mn decrease...

Baby corn is gaining preference as a vegetable across different parts of India but the availability varieties specific to baby purposes limited. To increase production, it essential study variability and stability genotypes that can be used for environments. Assessment genetic among 12 nine quantitative traits revealed days 50% silking cob weight are increasing yield. Environment plays predomin...

Tropical maize (Zea mays L.) represents a valuable genetic resource containing unique alleles not present in elite temperate maize. The strong delay in fl owering in response to long daylength photoperiods exhibited by most tropical maize hinders its incorporation into temperate maize breeding programs. We tested the hypothesis that diverse tropical inbreds carry alleles with similar effects at...

We conducted a synthesis analysis on data from 86 published field experiments conducted from 1903 to 2014 to explore the specific consequences of post-silking N accumulation (PostN) in New Era vs. Old Era hybrids on grain yield (GY) and recovery from plant N stress at flowering (R1 stage). The Old Era encompassed studies using genotypes released before, and including, 1990 and the New Era inclu...

This study was conducted in 2021 to the impact of planting date on maize inbred lines and determine their accumulated growing degree units (GDU).The experiment held at three agriculture research stations (Gemmeiza, Ismaelia Sids) with RCBD four replications. It planned provide also some insights optimize production mitigate climatic changes all researchers scientific community. Three dates i.e....

Improved phenotyping tools for simultaneously characterizing maize (Zea mays L.) genotypes with superior grain yield (GY) and N use effi ciency (NUE) would be benefi cial for breeding progress. Possible phenotypic predictors of the crowding intensity and N availability effects on maize plant N uptake, GY, and NUE were evaluated for different genotypes in two environments. Our objectives were to...

Abstract This study aimed to confirm the causality of climatic and soil physical factors on silage corn yield based climatesoil-yield network in Korea. The variables were growing degree days, high temperature, low surface rainfall, relative humidity, wind speed, sunshine duration before after silking. effective depth, slope drainage class soil. total digestible nutrients, dry matter fresh yield...

The present study was conducted to evaluate the genetic architecture of five diverse maize genotypes using combining ability analyses. General (GCA) mean squares were non-significant for grain yield and its related components. Specific (SCA) highly significant yield, number grains per row cob girth while days tasseling, silking, plant height, height length. These studies suggested preponderance...
