Abstract:
An experiment was conducted in the Floriculture Research Station, (Agricultural Research Institute) Rajendranagar, Hyderabad during August 2018 to October 2018 to investigate “Effect of Sampling time and Auxins concentration on rooting of Chrysanthemum cv. Chandamama Yellow”. The study revealed that among different sampling times, the cuttings taken in August recorded minimum days taken to emergence of sprouting, (20.17 days), maximum number of nodes sprouted per cutting (1.22), maximum number of leaves per cutting at 15, 30 and 45 DAP (5.16, 8.21 and 12.59 respectively), survival percentage (87.42%) is observed in nursery condition similarly in field condition also maximum survival percentage (84.64%), plant height (20.56 cm), number of branches per plant (5.65), length of branch (21.34 cm) is observed in the month of August. Among different auxins concentration minimum days to emergence of sprouting (18.68 days), maximum number of nodes sprouted per cutting (1.84), maximum number of leaves per cutting at 15, 30 and 45 DAP (6.44, 8.72 and 14.44 respectively), survival percentage (89.95%) was recorded with rootex-1 powder in nursery condition. In field condition maximum survival percentage (84.34%), plant height (26.41 cm), maximum number of branches per plant (5.78), length of branches (21.75 cm) was recorded with Rootex-1 powder. Among different treatment combinations i.e., sampling time and auxins concentration, minimum days taken to sprouting (14.37 days), maximum number of nodes sprouted per cutting (2.08), maximum number of leaves per cutting at 15, 30 and 45 DAP (6.81, 9.85 and 15.37 respectively), survival percentage (98.26%) is observed with August + Rootex-1 powder in August + IBA 500 ppm at nursery condition and maximum survival percentage (94.54%), plant height (33.33 cm), maximum number of branches per plant (7.20), length of branches (28.20 cm) was recorded with August+Rootex-1 powder at field condition.
