Rooting and Shooting Behaviour of Red and White Pulped Varieties of Dragon Fruit (Hylocereus undatus) in Relation to Indole Butyric Acid Concentrations
Subscribe/Renew Journal
The investigation was carried out to study the effect of IBA at different concentrations (2000 ppm, 4000 ppm, 6000 ppm) on cuttings of dragon fruit cultivars viz., red pulped variety and white pulped variety to elicit their ischolar_maining and shooting parameters. The cuttings of the red pulped variety performed better than the white pulped variety. Indole butyric acid (IBA) had significant effect on ischolar_maining and shooting performance of both the varieties over control. IBA @ 6000 ppm recorded minimum number of days for sprouting (43 days), maximum ischolar_maining and shooting parameters like percentage of ischolar_mained cuttings (86.77%), number of ischolar_mains (9.87), length of longest ischolar_main (22.93 cm), ischolar_main fresh weight (1.83 g) and dry weight (0.58 g), length of the longest shoot (23.93 cm), number of new shoots per cutting (4.00), shoot fresh weight (112.09 g ), shoot dry weight (9.47 g) and survival percentage (90.26%). The least performance was observed in the cuttings of white pulped variety for almost all parameters tested except for length of shoot.
