| Abstract:
To improve multiplication, the position effect of vegetal material and the indolebutyric acid effect on the rooting of Tilia semihardwood cuttings were studied. Shoot and sucker cuttings of T. cordata, T. platyphyllos, T. rubra and T. tomentosa were previously wounded and rooted with IBA at 0, 6000 and 10000 ppm under mist conditions. Percentage of rooted cuttings, mean root number per cutting and mean root length per cutting were recorded after 40 days. Shoot cuttings showed a low rooting ability. IBA treatment significantly improved rooting percentage of cuttings in T. cordata (43 – 61%) and T. tomentosa (5 – 32%), while mean root number and length were only slightly influenced by the hormone. Rooting success was greater when cuttings were taken from suckers, even in T. tomentosa (67%), but rooting was not stimulated by IBA. On the whole T. cordata gave the best results. | |
