Seed imaging analysis in seed technology research

Abstract

Seed testing is an important component of seed production systems. It is a dynamic activity as shown by the improvement of the available procedures and the development of new approaches and modem methodology. These tools comprise relatively new techniques such as seed and seedling imaging analysis that have indicated consistent potential to be used in basic and applied research. This proposal was designed with the collaboration of recognized seed technology researchers and promising younger professionals that have demonstrated sufficient qualification to guarantee the success of future actions in seed research. The members of this group represent important national and international institutions, comprising universities and research institutes located in São Paulo and Minas Gerais states, Brasilia and USA. The central theme is Seed imaging analysis and the proposal includes different approaches such as the evaluation of seed morphology by x-ray analysis and its possible association to performance as influenced by environment and seed physiological potential; the use of an automated computer imaging system (SVIS) to assess seed vigor, studies on seed maturation and seed priming in association of imaging analysis. Different grain crops, fruits, vegetable are included in the proposal such as cucurbits, maize, papaya, okra, bell pepper, castor bean and also some and Brazilian native species. Results will produce useful information to seed companies mainly to identify factors that affect seed performance, improvement of some available procedures to determine seed quality and establish consistent diagnosis necessary to solve problems. Depending on the information provided by initial results, the inclusion of new approaches and species will be considered, but all possibilities of distortion to the main focus will be avoided. (AU)
