Summary

THE A. DESCRIBES THE TEST PROCEDURE AND GIVES THE RESULTS OBTAINED AT 281, 288, 295 AND 302 K (8, 15, 22 AND 29 DEG C) FOR DIFFERENT VARIETIES OF OATS, WHEAT AND BARLEY. THERE IS A TEMPERATURE LEVEL ABOVE WHICH THE GRAIN DOES NOT GERMINATE WITHIN A FEW WEEKS AFTER HARVESTING. FOR BARLEY, ALL GRAINS FINALLY GERMINATE AT 295 K AFTER SEVERAL MONTHS, BUT NOT AT 281 K. THERE ARE DIFFERENCES IN DORMANCY ACCORDING TO SPECIES, VARIETIES, LOTS AND GRAINS OF A SAME LOT. THE STAGE AT THE BEGINNING OF GERMINATION IS SENSITIVE TO TEMPERATURE. AFTER THIS STAGE, GERMINATION CAN CONTINUE AT A HIGH TEMPERATURE. A.G.
