    Effect of growth regulators on in vivo budding in roses (Rosa hybrida L.)
    (Punjab Agricultural University, Ludhiana, 2017) Prabhjit Kaur; Grewal, H.S.
    The present investigations entitled “Effect of growth regulators on in vivo budding in roses (Rosa hybrida L.)” were carried out on the Research Farm, Department of Floriculture and Landscaping, Punjab Agricultural University, Ludhiana, during 2014-16. The experiments were conducted to study the effect of auxin on the rooting of the budded cuttings and cytokinin on bud take in Rosa hybrida L. in two different cultivars, viz. First Red and Grand Gala. The mature shoots (>1 yr old) of rootstocks, viz. R. indica var. odorata, R. multiflora and R. bourboniana were used for making the stem cuttings. In Experiment I, rootstock cuttings (8-9 inches long, pencil thickness) were treated with different concentrations of IBA for rooting and budded with the scion of rose cvs. First Red and Grand Gala in December- February. In Experiment II, the rootstock cuttings were treated with IBA 1500 mg L-1 for rooting and budded with the scion of rose cvs. First Red and Grand Gala after treating with BAP concentrations in December- February. The type of rootstock and growth regulators treatments significantly (p<0.05) affected the plant growth and flowering of two rose cultivars. The per cent sprouting, survival, shoot length, plant height, number of leaves and flowers per plant were observed the highest in rootstock R. indica var. odorata, whereas, per cent rooting and number of branches were at par in R. indica var. odorata and R. multiflora. The IBA treatment T4 (2000 mg L-1) was found the best regarding per cent sprouting (85.00, 81.67) and rooting of cuttings (91.67, 96.67) survival (68.34, 65.00), shoot length (13.64 cm, 16.29 cm), plant height (20.60, 20.66 cm), number of branches (3.20, 2.84), leaves (9.61, 10.94) and flowers per plant (3.08, 2.07) in rose cv. First Red and Grand Gala, respectively. The best BAP treatment for per cent sprouting (91.66, 88.34), survival (86.67, 86.67), shoot length (15.01 cm, 17.94 cm), plant height (23.01 cm, 24.15 cm), number of branches (3.53, 3.39), leaves (9.95, 11.31) and flowers per plant (2.21, 2.50) was in T4 (BAP 20 mg L-1) in rose cv. First Red and Grand Gala, respectively. It was concluded that the rootstock R. indica var. odorata performed better for First Red and Grand Gala among the different rootstocks tested. The auxin and cytokinin improved the vegetative growth and flowering of the rose plants. The treatment of cuttings with IBA @ 2000 mg L-1 and scion bud with BAP @ 20 mg L-1 were the best for the plant growth and flowering of cv. First Red and Grand Gala budded on R. indica var. odorata rootstock.
