The maximum survival percentage, plant height (cm), root length (era), numbers of roots and root weight per cutting were significantly higher in hard wood cuttings. IBA concentration had no speculative effect on plane tree cuttings. Thus, hard wood cutting was the best choice for plan tree propagation.展开更多

Rooting and sprouting percentages were higher in some treatments while other parameters were significantly higher in other treatments. The results of the present study revealed that rooting was significantly (p 〈 0.05) affected by the length of cuttings, as well as the position of shoots and type of cuttings. On average, 86.0 per cent rooting was observed in the 30-cm long cuttings com- pared to the other two lengths of cuttings, i.e., 20 and 25 cm, irrespective of any auxin treatment. In a control set, without any auxin treatment, a maximum of 60.0% rooting was recorded in the 30-cm long cuttings and a minimum of 40.0% of the cuttings rooted in the 20-cm long cuttings. Similarly, cuttings collected from the lower and upper portions of shoots resulted in 72.5 and 52.5 per cent rooting respectively, irrespective of auxin treatments. Maximum rooting was observed in the lower portion (40.0%) of cutting com- pared to the upper portion (30.0%) in the control set without auxin treatment. Leafless branches produced maximum (72.0%) rooting compared to the leafy cuttings (35.0%), irrespective of the auxin treatment. The leafy cuttings produces a minimum of 15.0% sprout- ing and rooting in the control set.展开更多
