| dc.description.abstract | The experiment was conducted in the nursery of the Department of Forestry in CCS, Haryana Agricultural University (India) during February and August season of 2003-04. The cuttings taken form 8 to 10 years old tree from three zones of canopy i.e. upper, middle and lower with thickness i.e. 0.5 cm to 1.0 cm diameter (thin) and 1.1 cm to 1.5 cm (thick). These cutting treated with different plant growth regulators viz. indole-3-butyric acid, indole-3-acetic acid, nepthalic acid at three concentration levels i.e. 1000 ppm, 500 ppm, 250 and combination of thiamine with 500 ppm of each growth regulator. The experiment was laid out in completely randomized design with three replication. The results revealed that cutting planted in February season gave better percentage of rooting (60.6%), number of roots per cutting (4.0), root length (12.0 cm) per cutting and weight of roots (0.37g) than August planted cuttings. All the roots characteristics obtained were better with thick cutting than thin cutting and canopy levels followed the trend of lower, middle and upper canopy i.e. cutting from the lower canopy gave best results. IBA 1000 ppm was most effective in sprouting (75.5%) and rooting (66.4%) of Dalbergia sissoo stem cutting. All the PGRs treatment gave significantly better results in both the season with all the canopy levels and with thick as well as thin cutting over control. From the studies, it was concluded that when the cutting of Dalbergia sissoo is taken from lower canopy with diameter 1.1-1.5 cm (thick) treated with indole-3-butyric acid 1000 ppm planted in February season gave the best results with respect to duration of sprouting, percentage of sprouting, number of leaves per cutting, number of roots per cutting, weight of root and shoot, percentage of rooting and rootshoot weight ratio and average length of root per cutting. | en_US |
