Key Points

This research evaluates how exogenous auxin and cytokinin hormones affect growth and photosynthetic pigments in Adenium obesum.
Conducted a fully randomized experiment with 8 treatments and 1 control across 4 replications over 8 spraying stages.
Applied two types of auxin hormones (IAA and IBA) and two types of cytokinin hormones (BAP and KIN) at specified concentrations.
Evaluated leaf area, number of lateral buds, flower count, and weight metrics for shoots and roots.
IAA+BAP treatment significantly increased leaf area and the number of lateral buds.
Hormonal treatments positively affected root length, except for IBA and IBA+BAP, which showed no significant effect.
Chlorophyll content increased under IAA+BAP and KIN treatments, while carotenoid content remained unaffected.

Assesses growth factors and pigment content in Adenium obesum, suggesting hormonal treatments can enhance plant responses.
