The objective of this study was to develop a rapid non-destructive technique to estimate total chlorophyll (Chl) content in a maize canopy using Chl content in a single leaf. The approach was (1) to calibrate and validate a reflectance-based non-destructive technique to estimate leaf Chl in maize; (2) to quantify the relative contribution of each leaf Chl to the total Chl in the canopy; and (3)...

in order to investigate the effect of zinc element application on growth and some morphophysiological of maize (single cross 704) an experiment was conducted during 2010 at greenhouse. experimented design was complete randomize factorial with four replications. treatments of experiment were soil salinity (4, 8 ds.m-1 and 0 as a control) and different zinc concentration including 0, 10 and 20 mg...

Non-additive gene regulation has been recently suggested as an important factor promoting phenotypic variation and plasticity. In order to obtain a description of gene expression status at an early stage of ear development in a maize (Zea mays L.) F1 hybrid as relative to its parental inbreds, we compared gene expression profiles in immature ears of elite inbred lines B73 and H99 to one of thei...
