When the testae of seeds of peas Powell, and cowpeas Asiedu and Powell, were scarified before imbibition, leading to more rapid water uptake, the extent of living tissue declined much more markedly in aged than in unaged seeds. He was an active member of the PDC for many years.

The transition to a free-market has therefore been a difficult process, except where profitable hybrid crops like maize and sunflower predominate, as in some East European countries.

In the afternoon visit to the town of Mantua. Comparisons of cultivars of cowpea Vigna unguiculata differing in seed coat pigmentation. The relative er- Call for Registration New as of June ! The test is both quantitative and repeatable. In this workshop we will present and discuss the technical and scientific challenges in AP testing and provide hands-on training in the current process and PCR methodologies utilized for biotech trait detection: The local organizers would like to thank the lecturers and the Membership Department of the ISTA Secretariat for all the work done making this workshop successful.

To assist laboratories to meet the specifications for temperature control and measurement given in the ISTA Rules an illustrative SOP is included in the handbook: The levels of leakage were not associated with the extractable solute content of the embryos Matthews and Rogerson, Seed Science and Technology, 25, The subsequent decline in leakage as the embryos imbibed was explained by the formation of the normal bilamellar membrane following hydration, which restricted leakage.

The role of split seed coats in determining seed vigour in commercial seed lots of soyabean, as measured by the electrical conductivity test. He was also a good teacher and gave lectures at the University and organised both national and international courses. With the decline of that system, these countries are now in a process of economic transition. Through a wide variety protection. Kent Bradford, in the chair for the Vigour and Invigoration session, will highlight the science behind methods of evaluation and improvement of seed quality for the crop production systems of today.

Accommodation will be in the city of Angers. The association will explore the possibilities of distance learning programmes. In addition to the basic science courses some specific topic were suggested; seed identification, and tetrazolium, germination and purity testing.


Laboratory 5 evaluates more abnormal seedlings than the other laboratories, especially when the root length is less than half the size of the shoot part seedlings 2, 5 and 7. The initial characteristics of B. The theoretical background will be given through lectures. Accredited laboratories are expected to comply with the requirements and document the procedures adopted in their laboratory.
