THE INFLUENCE OF OSMOCONDITIONING IN POLYETHYLENE GLYCOL (PEG 6000) ON THE GERMINATION AND EMERGENCE OF CARROT AND PARSLEY SEEDS
The experiment was carried out in 1990. Two samples of carrot seeds of cv. "Perfekcja" with the germination capacity of 87% and 64% were taken as well as two samples of parsley seeds of cv. "Berlinska" with the germination capacity of 83% and 51%, respectively.
The time and the temperature of conditioning were investigated.
Before conditioning seeds were dressed for 2 hours in 0.2m solution of thiram in acetone.
On the basis of obtained results it has been established that dressing and conditioning resulted in a statistically significant increase by a few percent of the number of germinated carrot and parsley seeds.
In the field over-all number of carrot was low and amounted to 24–31% and 20–29% for samples with the germination capacity of 87% and 64% respectively.
The emergence of parsley was scarce and amounted to 16–25% and 8–21% for samples with 83% and 51% germination ability, respectively.
However, dressing and conditioning had a considerable influence on the increase of carrot and parsley root yields from samples with 87% and 51% germination capacity.
