Investigation and Standardization of Vegetative Propagation Methods in Hibiscus rosa-sinensis cv. Hawaiian

摘要

The effect of different propagation methods (side-grafting and T-budding) and propagation times (1st and 15th June and 1st July, 1999) on the growth of Hibiscus rosa-sinensis cv. Hawaiian was studied. Statistical analysis of the data indicated that minimum days (15.33) to sprouting were taken by plants side-grafted on 15th June, while maximum days (73.00) were taken by plants T-budded on 1st June, 1999. Highest shoot length (9.19 cm), shoot diameter (3.2 mm), number of shoots per plant (3.00) and number of leaves per plant (18.33) were recorded in plants side-grafted on 1st July, 1999, while least shoot length (2.64 cm), shoot diameter (1.26 mm), number of shoots per plant (1.00) and number of leaves per plant (7.33) were noted in plants T-budded on 1st June, 1999. The best propagation method found for Hibiscus rosa-sinensis cv. Hawaiian is side-grafting in early July, or T-budding in mid June.
