Response of cuttings of different carnation (Dianthus Caryophyllus L.) cultivars to rooting hormones

Abstract

The experiment entitled Response of cuttings of different carnation (Dianthus caryophyllus L.) cultivars to rooting hormones was conducted at Department of Horticulture, Naini Agricultural Institute, SHUATS, Prayagraj during November to March, 2019-20. Experiment was laid out in a FRBD having 3 cultivars and 7 rooting hormone concentrations consisting of 21 treatments with three replications. The results revealed that among the varieties studied, variety Liberty recorded maximum rooting percentage (89.5%), Plant height (81.9 cm.), No. of leaves per plant (128.7), No. of shoots per plant (5.3), Minimum Days to flower bud initiation (116.3), Minimum Days to flower bud opening (19.9), Flower diameter (6.8 cm.), Vase life (7.1) and No. of cut flower stalks per plant (9.8). The data on different concentrations of rooting hormones studied revealed that concentration of IBA @ 400ppm (R2) was superior compared to the other treatments with respect to Maximum rooting percentage (97.4%), Plant height (85.1 cm.), No. of leaves per plant (130.1), No. of shoots per plant (5.4), Minimum Days to flower bud initiation (115.2), Minimum Days to flower bud opening (17.2), Flower diameter (8.0 cm.), Vase life (8.1) and No. of cut flower stalks per plant (11.0). Interaction data revealed that treatment T3 (V1R2) Liberty + IBA @ 400ppm recorded maximum rooting percentage (98.5%), Plant height (85.5 cm.), No. of leaves per plant (130.2), No. of shoots per plant (5.4), Minimum Days to flower bud initiation (115.1), Minimum Days to flower bud opening (17.6), Flower diameter (8.3 cm.), Vase life (8.1) and No. of cut flower stalks per plant (11.1).
