Shalini Kaushik and Neeraj Shukla
The objective of the current review is to review and identify the research on the effect of IBA, NAA and their combination effect on shooting and root growth of ornamental crops specially African marigold (Tagetes erecta
L.) cuttings. Factors affecting rooting of ornamental crops cuttings can be internal or external factors. Internal factors affecting rooting of cuttings include the amount of stored food in cuttings, the age and maturity of tissue, the formation of callus and adventitious roots and the presence of leaves and buds on cuttings. The external factors include rooting media, chemical and hormone treatments, light, temperature, mechanical treatment and mist spray. IBA, NAA is one of the most important factors for cutting production. Types of rooting hormone have significantly influenced the rooting and vegetative growth of cuttings. The concentration of rooting hormone depends on the species, type of cuttings, growing conditions, season of the year and the cost effectiveness of the rooting hormone components. Choosing the most suitable concentration of rooting hormone for the achievement of a successful plant production is very important which is significantly helpful for the farmers for off season production of ornamental crops through cuttings
