| dc.description.abstract | The present investigations entitled “Effect of different growth regulators on rooting of stem cuttings in Bougainvillea” were undertaken at research farm of Department of Floriculture and Landscaping, Punjab Agricultural University, Ludhiana in difficult to root Bougainvillea varieties viz. Shubra, Lady Mary Baring and Zakiriana during 2015-16. In all the three varieties, stem cuttings were treated with different growth regulator concentrations and combinations for long duration (12h) and quick dip (<5 sec) and planted in the polybags containing garden soil. In the cuttings treated for quick dip (<5sec), IBA 2000 ppm resulted in maximum mean number of shoots (1.64), mean shoot length (7.07 cm), mean number of leaves (24.91), mean number of branches (2.17) and mean number of roots (3.75) of cuttings among all the growth regulator treatments. The treatment with NAA 2000 ppm resulted in maximum mean shoot emergence (35.56%) and establishment of plants (32.22%), however, treatment with NAA+IBA (100+500) ppm resulted in maximum mean root length (10.50 cm). Among all the three varieties, Zakiriana was the best with maximum shoot emergence (35.00%), number of shoots(1.30), average shoot length (5.10 cm), number of leaves (25.02), number of branches (1.30), number of roots (2.49), average length of roots (9.04 cm) and establishment of plants (32.33%). In the cuttings treated for long duration (12h), NAA+IBA (100+100) ppm resulted in maximum mean shoot emergence (40.00%) among all the growth regulator treatments. The treatment with IBA 500 ppm resulted in the maximum mean number of shoots (1.86), mean shoot length (7.11 cm), number of branches (1.84), number of roots (3.07). The treatment with NAA 500 ppm resulted in maximum mean number of branches (1.84), however, treatment with NAA+IBA (50+100) ppm resulted in the maximum mean number of leaves (28.81). The maximum mean per cent establishment (35.56%) of plants was observed in treatment with NAA+IBA (100+50) ppm. Among all the three varieties, Zakiriana was the best with maximum shoot emergence (44.33%), number of shoots(1.69), average shoot length (6.12 cm), number of leaves (30.80), number of branches (1.72), number of roots (2.64), average length of roots (13.25 cm) and establishment of plants (39.67%). | en_US |
