Abstract

Naturally, germination takes place under the soil surface hidden from the eye of the observer. Therefore, the main goal of the experiment is the understanding of the germination process in correlation with the growing degree days. The experiment is performed on samples of 100 untreated barley seeds placed in Petri dishes, subjected to four fixed temperatures, 5°C, 10°C, 15°C and 20°C, in four incubators, continuously over a period of 6 days. From the 3^rd to the 6^th day, a sample is taken from each incubator and the following data is collected: the number of germinated seeds, the number of stems, the length of the longest radicle, and the length of the stem. The data analysis shows that the barley seed germination rate reaches at least 50% after reaching 30 degree-days.
