ISHS Acta Horticulturae 215: Seed Research in Horticulture

Already the ancient sentence: "As the seed, so the yield" shows the importance of the seed for the plant production. Agricultural and horticultural products of high quality together with lower prices are, through the evidence of oversupply of agricultural products in the European Community, really necessary for the competitiveness and only possible by using high quality seeds. Therefore in future the seed production will hold a key position.

Like in all biological systems there are also specific physiological characteristics in seeds which can cause difficulties in cultivating a crop. Remember for example insufficient or absence of germination of lettuce in summertime caused by higher soil temperatures. Thus economical losses for the growers and insufficiency of market supply can occur. Therefore we welcome the work done by horticultural scientists on seed-problems, as this symposium with its great number of themes is impressively demonstrating. During this international symposium here in Geisenheim important fields of seed science will be discussed. The seed production, the germination and the seed storage will be illustrated. The latter has become an important field of research. By the long term storage of seeds, a steady supply is even after bad seed harvests, guaranteed. It is on the other hand possible with the aid of storage, to preserve the gen potential of different crops as is already practised in the genebank of the forestry in Hessia.

In the other sessions of the symposium important themes as dormancy, pretreatment and vigour will be discussed.

The Hessian Government welcomes that the Council of the International Society for Horticultural Science has agreed that the Third Seed Symposium with the title: "Seed Research in Horticulture", takes place at the Research Station Geisenheim and that the Council has charged Dr. Meinolf Kretschmer, Honorarprofessor at the Fachhochschule Wiesbaden, to organize and lead this symposium. This assignment is due to the amount of research work done by Dr. Kretschmer, who has for the last 15 years mainly been involved in horticultural seed research.

I want to give the best regards of the Hessian Government to all of you. I wish you a pleasant stay in Hessia and a very successful symposium with many results.

Mr. Chairman, Ladies and Gentlemen,

I am glad to see you and as convener of this third Seed Symposium of the International Society of Horticultural Science with the working title: Seed Research in Horticulture, I welcome you.

I welcome the Past president of ISHS, Professor Dr. Fritz from Weihenstephan and the chairman of our ISHS working group "Seed Production", Dr. George from the United Kingdom. I welcome the representative of the Ministry of Agriculture at Wiesbaden, Mr. Herda, and I say thanks for his impressive words. I welcome also the chairman of ISTA Vigour Committee, Dr. Fiala, from Austria. I think now is a good opportunity to point to the necessity of cooperation between the ISHS working group and the different ISTA committees. I should not forget to say welcome to the chairman of the working group of the German Seed Testing Station, Dr. Schmidt, from Karlsruhe.

The First Symposium was held at Nottingham in 1977 and convened by the unforgettable Dr. Walter Heydecker, the Second Symposium was held at Castro Caro in 1980 and planned by Prof. Quagliotti and we now have the Third Seed Symposium at Geisenheim.

Dear Collegues, nature scientists as well as seed scientists see the fascination of science during their work in the laboratory and during meetings like this. First there is the possibility to find out the law of cause and effect. On the other hand there is the chance to help the farmers with their results of research but in general there is the aime to support mankind especially those people who are hungry.

Another fascination of science is, that borders are unknown. The great number of participants of our symposium from different countries confirms this. Furthermore, another attractive effect is that there are no borders of ideology in science. As an example the phytochrome shows reactions everywhere only by light-red or far-red light, and the germination of many seeds is prevented by higher temperatures all over the world.

Dear collegues, I thank you very much for your coming, from whatever country you are. I ought to say that I am very glad to meet the collegues from Israel, especially Dr. Globerson and Dr. Perl, with whom I worked together in their laboratory at Bet Dagan.

I also say very much thanks to everybody who helped me with the organization so that it is possible for us to work together for a few days at Geisenheim. I give my thanks to the head of our Institute, Prof. Dr. Hartmann and his coworkers, especially to Mrs. Waldhör. I want to give many thanks to the head of the Administration Mr. Siemokat and his staff too and last but not least I have to say thanks to the chairmen of our Symposium, Dr. George, Prof. Cantliffe, Dr. Perl, Professor Karssen and Dr. Globerson.

I wish everybody a successful symposium. Again thank you very much for your coming and your help, Danke schön!

Prof. Dr. M. Kretschmer
