PAPER TITLE;
Consistent Relationship of Both Watercontent and Activity With Maize Seed Quality Indices
ABSTRACT;
Seed quality can be explained using a range of indices that are acceptable within the standards set by the International Seed Testing Association. There is a need to improve existing models to explain the wellknown variations in seed quality within and between crop species. The objective of this study was to determine the consistency of using grain water occurrence to explain seed quality in terms of viability and vigour in maize (Zea mays L.). Four sites were used over two seasons to grow three cultivars in order to monitor changes in water content, water activity, dry mass and total starch observed in different cob sections (tip, medium and bottom) at 30, 60 and 90 days after pollination. Seed quality was determined based on the germination and vigour of physiologically mature kernels. It is concluded that grains that seed quality is linked to the water activity and position on the cob.
