Abstract:
An experiment was conducted to study the effect of different plant growth regulators and media on shooting of stem cuttings in dragon fruit (Hylocereus undatus) at Centre of Excellence on Protected Cultivation and Precision Farming, “Indira Gandhi Krishi Vishwavidyalaya, Raipur, Chhattisgarh. Dragon fruit cuttings treated with different plant growth regulators and media revealed that the cuttings grown in media M₂ -Soil: Sand: Cocopeat: Vermicompost (2:1:1:1) performed better than media M₁ -Soil: Sand: Cocopeat: FYM (2:1:1:1). Among different plant growth regulators, IBA @ 7000 ppm recorded minimum number of days taken to sprout initiation (35 days), maximum number of sprouts per cutting (1.72, 2.78, 3.64 and 4.22 at 30, 60, 90 and 120 DAP respectively), maximum length of shoot (9.42 cm, 12.78 cm and 18.28 cm at 60, 90 and 120 DAP respectively), maximum shoot fresh weight (123.74 g), maximum shoot dry weight (12.63 g) and maximum survival percentage (98.34%). The study revealed that IBA @ 7000 ppm and media M₂ -Soil: Sand: Cocopeat: Vermicompost (2:1:1:1) had significant effect on improving shooting of dragon fruit cuttings.
