The asexual seed was extracted<br />from an established plantation that was harvested during four<br />years with pruning intervals of 56-112 days. The selected<br />branches were divided into three cuttings, 40 cm long with at<br />least three buds in the basal, medial and apical parts of each<br />branch. The highest percentage of rooting and sprouting in a<br />35-day period was observed in the 112 day-old cuttings: 9%<br />sprouts, 12% roots and 31% with both sprouts and roots. The<br />optimum age of the branch to obtain maximum sprouting and<br />rooting was estimated at 117 days. The cuttings taken from<br />the basal and medial portions of the branch had 10% more<br />sprouts and roots than the cuttings taken from the apical part.<br />There were noticeable differences between the application or<br />not of IBA (P≤0.01). Depending on the age of the cutting<br />and the part of the branch it was taken from, the use of IBA<br />caused an 11 to 15% increase in total sprouting. ER -
