TEMPERATURES, INCUBATION PERIODS, OSMOTIC POTENTIALS AND RATE OF GERMINATION OF FLORENCE FENNEL "SEEDS" AT OPTIMAL AND CRITICAL TEMPERATURES

G. Damato, S. Vannella, R.J. Downs
"Seeds" of Florence fennel (Foeniculum vulgare Mill. var. Azoricum Tell. cv. Locale di Bari) were osmotically primed in 0, -9, -12 or -15 MPa polyethylene glycol 8000 at 10, 15 or 20°C for 6, 12 or 18 days before germination at 15, 25 or 35°C. Priming had little effect on germination at 35°C.(11%). Increasing temperature during priming shortened of 1.2 days the time to achieve the final germination; osmotic potential and priming duration improved the speed of germination.
