Germination capacity of loaded seeds was controlled and safe load limit for pea seed was found. Two varieties of pea seed for investigation were used. The range of stress level 1-20 MPa were applied and compression was repeated up to 50 times. In order to set seed for germination test were used the cassette design by author. Germination capacity decreases with the increase of compression and the force caused decrease of germination capacity was 5 times higher than elasticity limit.
W pracy dokonano oceny wyników badań procesu konwekcyjnego suszenia ziarna pszenżyta w grubej nieruchomej warstwie dla ziarna bezpośrednio zebranego z pola i nawilżanego sztucznie do tej samej wilgotności oraz określono wpływ parametrów suszenia na wskaźniki energii i zdolności kiełkowania nasion poddanych temu procesowi.
The effect of water potential of pellets on germination of sugar beet seeds was investigated. Very low (negative) pellets water potential decreased speed of germination and germination ability in conditions of water shortage. As germination process proceeded, water potential of pellets increased gradually. Differences between water potentials of different types of pellets decreased during germination.
