Effect of rooting hormones in propagation of dahlia (Dahlia variabilis L.) through stem cutting

Author(s):

Bharti Sao and LS Verma

Abstract:
A study on the impact of auxins (IBA and NAA) on two cultivars of dahlia (Dahlia variabilis L.) was conducted at Department of Floriculture and Landscape Architecture, College of Agriculture, Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.), during the year 2019-20. The study revealed that among the two cultivars (Kenya Blue and Kenya Yellow) experimented, the highest rooting percentage was recorded in the cultivar Kenya Blue (62.46%) which was significantly higher than the rest one. Similar tendency of superiority was observed for survival percentage, number of roots per cutting and root length, wherein the cultivar Kenya Blue took the least number of days for root initiation (18.11 days). As for the different concentration of auxins used, IBA at the rate of 1000 ppm resulted in the maximum rooting percentage (69.82%) as compared to the rest of the treatments. Similar tendency of superiority was observed for number of roots per cutting and root length, wherein IBA at the rate of 250 ppm + NAA at the rate of 250 ppm took the least number of days for root initiation (17.21 days). The highest survival percentage was recorded with treatment of NAA at the rate of 500 ppm (63.96%) followed by NAA at the rate of 1000 ppm (56.39%).
