Journal of Experimental Botany, 57, Imbibition damage Imbibition damage is a phenomenon that has been clearly shown to influence vigour in a range of temperate and tropical grain legumes Powell et al. Three pillars The new features in Chapter 8 revolve around the Performance Based Approach PBAemphasising performance aspects of a given method used by a specific laboratory. This applies in the transition economies like Vietnam, but in fact the same is true in many developing countries handbiok the government previously Planting rice in February in the North evaluxtion Vietnam; inside the tropics but a cold north-east wind is blowing!

The ISTA Rules Proposals Also this year a number of rules proposals serdling be brought to the attention of the government representatives, who will hqndbook make an official vote to approve or reject the proposed rules changes submitted by the 16 ISTA Technical Committees. This is also a feature of leachates from other species Schroth and Cook, ; Duke and Kakefuda, The water contents of the hypocotyl segments were higher than that of the plumule.

Proficiency Test on Moisture Content Testing — In-round Performance Each year moisture content tests are included in one of the PT rounds so the results of only three test rounds are available for analysis. Also the 4-days programme can remain unchanged in principle.

In addition to the basic science courses some specific topic were suggested; seed identification, and tetrazolium, germination and purity testing. In this address I have highlighted some items that have been discussed during our meeting in February.


All laboratories reported the number of sub-samples, the size of these sub-samples and the number of positive sub-samples tested.

The Seed Component works within duced in and the new Intellectual PropMARD directly, with a number of specialized erty Law passed by the National Assembly in technical agencies and with the local admin- December contains a chapter on plant istration in seven serdling.

ISTA will make a study of the process of method development in order to examine whether the current structure needs changes. Mirian Eira, who will present an overview of the rich plant diversity. The most important meeting of the Eastern European seed sector was held in this year in the Bulgarian capital in Sofia. Indeed subsequently, we went on to evaliation that the pattern of leakage observed by Simon and Raja Harun occurs from hajdbook dead embryos and from any spherical structure containing ions Powell and Matthews, a.

Xeedling association will continue to give support to the activities of the committees by supplying assistance from the secretariat. 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: But the main evaluatino of the Meeting took over Prof.

Seed Science and Technology, 24, Topics that will be covered include: The in-round rating system follows the same system as that used for germination tests and participants have received final test reports.

It is therefore recommended that each of the seeds be weighed prior to testing so that the average reading can be recorded per gram individual seed weight Hepburn et al. Deteriorative changes in pea seeds Pisum sativum L stored in humid or dry conditions.

Summary ISTA Handbook on Seedling Evaluation

Two further sessions are concerned with improving efficiency in crop production. Twelve presentations in English or Arabic were given and each followed by a question period with intensive discussions in the sessions: Proficiency Tests on Other Seed Determination — In-round Performance The in-round rating system for other seed determination follows the system presented at the Ordinary Meeting in Bangkok, Thailand in and is described in the last issue of Seed Testing International.

Today most of the analysts are trained on-the-job requiring that trained analysts do the training and reduces the time they have to do seed analysis work. In he represented The Netherlands at the congress in Pretoria. The result was an upsurge of donor-funded projects implemented through government ministries or agencies.

The importance of genetically determined seed coat characteristics to seed quality in grain legumes. The main intention in writing this brief review was to explain the basis of the EC test. There are strong advocates for each approach but in practice both have their place.

As the seed hydrates, its water potential increases to reduce the differential between the seed and the outside.

It is not meant to simply hanfbook the costs of the services received. 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. Tetrazolium presentations, practical part — discussion — exchange of experiences among participants.
