Determination of the best temperature and dry condition in carrot primed-seeds.
Seed priming and drying condition effects were investigated immediately after seed-priming and 9 week after the storage. In this experiment, carrot seeds of 'Forto C.V.' were used. These seeds were individually primed for 10 days at 20 degrees C and in PEG (6000) (273 g L(-1)) and KNO3 (200 mmol) solutions. Then they were dried for 1 and 2 h at 15, 25 and 30 degrees C, respectively. One part of the seeds was stored at 5 degrees C in RH/45% For 9 week. Chemical priming effects, drying temperature as well as germination temperature on different traits especially germination percentage were significant. However, drying time had no significant effect on germination percentage after storage period. PEG priming and drying at 25 degrees C for 2 h provided the best condition for germination percentage. Using the best material for pre-priming, along with suitable drying management with appropriate quality and good conditions of the storage is important.
