The seminar started with an interesting history presentation by Professor Adolf Steiner on the pioneers of statistics in seed testing and chairpersons of the statistics committee. He was an active member of the PDC for many years.

Methods and techniques on disclosing modified foods and capacity building. The identity and quality Large istx mechanization is difficult but many of varieties must be preserved from sowing, small machines like sedling are used for land preparation, sowing and harvesting 16 Obituary Kees Langerak – By Ruud van den Bulk and Joost van der Burg Plant Research International, Wageningen, The Netherlands It is with great sadness that we have to inform you that our former colleague Dr.

Summary ISTA Handbook on Seedling Evaluation

Accreditation of staff and seed testing labs is now high on the agenda as MARD intends to devolve much of the responsibility for seed quality to those who produce and market it. This has special implications for seed supply which was an integral part of the central planning process, and highly structured as a istx.


The challenge is by no means insurmountable, needing a methodical scientific approach Seed Testing International No. The highest were calculated for the 0.

The significance of damage during imbibition to the field emergence of pea Pisum sativum L seeds. This covers the annual costs of ISTA publications.

To assist laboratories in ensuring that the germination media they use in germination tests meet the specifications given in the ISTA Rules, the following four illustrative SOPs are included in the handbook: Mature Bruguiera gymnorrhiza seed.

Imbibition damage results from the rapid entry of water into the cotyledons during imbibition, leading to cell death and high solute leakage from the seeds Powell and Matthews, a. Work on these crops is underway within ISTA, and will move on to other grain legumes.


Reading evapuation acceptance of Minutes 5. The document has been circulated to the members and is also available for download on the ISTA Website. Danida is assisting this process through staff training and a soft-loan scheme for equipment.

Leakage during evalhation imbibition. The Executive Committee is also in favour of continuing a triennual cycle for the congress, starting with the seed symposium, followed by open technical committee meetings and the ordinary meeting. The further to the right that a seed lot is placed on the initial decline, the lower the germination.

International Seed Testing Association, Switzerland. Chair and lead speaker: All the participants in the Seed Symposium in May are sure to be impressed when they see and experience for themselves the energy and commitment to seed technology in Brazil.

The conductivity of pea seed soak water was found to be closely correlated with both the sugar and amino acid content, indicating general solute loss from seeds Mat- Figure 1: Bulk samples of 50 seeds are soaked in deionised water and the EC of the soak water is measured after 24 hours.


The seed technology problems associated with developing the potential of undomesticated species is covered in the session on the Domestication and Use of Non-Crop Species, chaired by Dr.

Several working groups are working on various numbers of items. This program would greatly help prepare prospective seed analysts for taking the certification or registration tests of the Association of Official Seed Analysts and the Society of Commercial Seed Analysts.

Rapid evaluation of the storage potential of seed peas. The executive committee will seek cooperation with other associations that are active in the field of seed science. There is clearly potential for a 24 hour test of germination based on the electrical conductivity of the soak water of bulk samples of seeds.

Final post-workshop tour booking and payment will be done upon arrival to Kenya.

Biochemical analyses and hypotheses about seed deterioration suggest impaired membrane activity is a factor leading to leakage McDonald, In most cases, viability declined at a higher axis water content, than indicated when the water content was determined on evaluatin whole seed basis only in the case of S.
