| Seed market is becoming global and globalization is growing very fast. To compete favourably in this new global seed world, quality and cost are and will be certanly the key issues. High seed quality can only be obtained by a thorough control of the entire seed production process, step by step from planning to final delivery. That requires science, technology, expertise, experience, good management and certanly, the most important, an absolute and unconditional commitment with quality. Seed testing for quality assurance is one important step in the process of production of high quality seed. In the late years a considerable amount of research has been published, particularly on the use of some Polymerase Chain Reaction DNA based new technologies (RAPD,... |

| Among the principles used for the evaluation of seed vigor, two approaches are predominant: seed resistance to stresses and the direct or indirect identification of the "current" state of the seeds, e.g., enzymatic activity, integrity of the cellular membranes, growth parameters. In this presentation recent innovations are discussed in procedures for seed vigor evaluation emphasizing the methodologies of accelerated aging with salt saturated solutions, controlled deterioration and potassium leachate tests. These tests, performed at seed the laboratory of ESALQ/USP, in function of their simplicity and efficiency, deserve the attention of seed technologists. |
