Abstract:
This study was conducted to assess the grafting success and morphological characters of scion and rootstock of ornamental cacti. Different scions (Gymnocalycium spp. (7 types) and Echinopsis multiplex) were grafted on rootstock Hylocereus undatu. The scion length and width was found to be maximum in T₃ (E. multiplex on H. undatus) as 1.15 cm and 5.20 cm. Number of areoles was maximum in T₆ (G. mihanovichii (Yellow) on H. undatus) as 31.00. Number of spines per areoles and number of spines per plant was found maximum in T₃ (E. multiplex on H. undatus) as 11.50 and 240.50. Success percentage and survival percentage was maximum in T₃ (E. multiplex on H. undatus) as 80%.
