Effect of Exogenous Application of Auxin on Leaf Cuttings of Mexican Snow Ball (Echeveria elegans Rose)

Aims: Succulents are on the rising trend of popularity due to its compromising behaviour with watering and durability indoors, creating a peaceful and healthy living condition. Thus it is the need of the hour to find a suitable propagation method or use of exogenous substances with propagation to assist regenerating new plants.

Study Design: The experiment was laid out in randomized block design (RBD) with three replications.

Place and Duration of Study: The present investigation entitled Effect of IAA and IBA Application on leaf cuttings of Mexican Snow Ball (Echeveria elegans). Was conducted in Research Field, Department of Horticulture, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, during February, 2021 to April, 2021.

Methodology: The experiment was laid out in randomized block design (RBD) with three (IAA 100 ppm, IAA 300 ppm, IAA 500 ppm, IBA 100 ppm, IBA 300, IBA 500 ppm, IAA + IBA (100 ppm + 500 ppm), IAA + IBA (500 ppm + 100 ppm) and Control replications. The treatment in each replication was allotted randomly. Nine treatments having one variety were tried in the experimental design.

Results: The results revealed that among all the treatments, application of IAA + IBA (100 ppm + 500 ppm) in treatment (T8) took minimum days to rooting (9.00), number of leaves (16.56), number of shoots (2.56), shoot height (15.56 mm), shoot diameter (16.44 mm), root length (29.00 mm) and in economic point of view treatment T8 IAA + IBA (100 ppm + 500 ppm) was found to be most economically viable in terms of gross return (Rs. 17,000), net return (Rs. 11,100) and benefit cost ratio (2.88).

Conclusion: According to the present investigation it is concluded that treatment IAA + IBA (100 ppm + 500 ppm) was found most effective in terms of growth of Echevaria (Echevaria elegan).
