The Maize Seed Anatomy of the Mature Maize Seed
The pericarp consist in the transformed wall of the ovary that covers the seed and acts as a protection for the embryo and endosperm. It takes the place of the seed coats or integuments in the ordinary seeds, which in maize are reduced to unnoticeable remnants in the mature kernel. A thin, suberized nucellar membrane derived from the outer epidermal wall of the nucellus persists as a continuous...
متن کاملSingle seed precise sowing of maize using computer simulation
In order to test the feasibility of computer simulation in field maize planting, the selection of the method of single seed precise sowing in maize is studied based on the quadratic function model Y = A×(D-Dm)2+Ym, which depicts the relationship between maize yield and planting density. And the advantages and disadvantages of the two planting methods under the condition of single seed sowing ar...
متن کاملScientific Correspondence Cytometrical Evidence That the Loss of Seed Weight in the miniature1 Seed Mutant of Maize Is Associated with Reduced Mitotic Activity in the Developing Endosperm
“If you know a thing only qualitatively, you know it no more than vaguely. If you know it quantitatively—grasping some numerical measure that distinguishes it from an infinite number of other possibilities—you are beginning to know it deeply.” (C. Sagan, Billions and Billions, 1997). Using new approaches to quantitative image analysis, we provide the first direct evidence, to our knowledge, tha...

متن کاملA rare SNP mutation in Brachytic2 moderately reduces plant height and increases yield potential in maize
Plant height has long been an important agronomic trait in maize breeding. Many plant height QTLs have been reported, but few of these have been cloned. In this study, a major plant height QTL, qph1, was mapped to a 1.6kb interval in Brachytic2 (Br2) coding sequence on maize chromosome 1. A naturally occurring rare SNP in qph1, which resulted in an amino acid substitution, was validated as the ...
