Russo-german War May Affect Work of Jewish Scientist in London

A London Jewish scientist is closely watching the progress of the Russo-German conflict for the large-scale applications of his researches are threatened by the extension of the war. He is Professor P. G. Gregory, of the Imperial College of Science and Technology, South Kensington.

Dr. Gregory and his woman assistant, Dr. Purvis, have carried out many experiments in this country into the process of seed treatment which we call vernalization and the Russians yarovisation. Vernalization consists of germinating seeds of any of the grains, and then freezing them in a refrigerator. When the seeds are taken out and sown in the ordinary way they grow faster than normally, and the wheat or barley plants produce ears earlier.

Tests at the Odessa research station have shown that vernalized wheat matures in 64 days; ordinary wheat takes 81 days. Professor Gregory’s work has been carried out with rye plants, chiefly in the grounds of Chelsea Physick Gardens on the Embankment.
