| Abstract:
"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. | |
