anglais. This research, conducted at the Fruit Tree Research Institute of Rome, focused on the study of rizhogenic capacity of seabuckthorn (Hippophae rhamnoides L.) propagated by woody cuttings. Cuttings of 15 cm long and about 3 mm in diameter were harvested from seven clones. A basal incision was made on half of the cuttings. All cuttings were treated with a solution of 1000 ppm of potassic IBA for 5 seconds. The cuttings were placed in a bed with humid coconut peat; a basal electric heater maintained the bottom bed temperature at 20 deg C for 30 days. The percentage of rooting, the number and length of roots were recorded. The results indicated that the species had good rooting capacity (average 63,7%); however, high variability within the clone population was observed. Basal incision stimulated the increase of rooting

Dopo il trattamento con IBA potassico 1.000 ppm, le talee si pongono in substrato costituito da torba di cocco, riscaldato a 20 gradi C per 30 giorni in ambiente esterno. L'incisione corticale della base delle talee favorisce la formazione dell'apparato radicale specialmente in quelle di maggior diametro
