Exogenous Auxin Role on Shallot (Allium cepa Var Aggregatum) Growth

Gina Aliya Sopha and Shinta Hartanto

Abstract:
Background and Objective: Shallot was reported with a high concentration of auxin, Indole Acetic Acid (IAA) and auxin's application might affect plant growth. However, the effect varies on plant species and genotype. This study aimed to determine the IAA concentration in shallot tissue and investigate the effect of exogenous IAA application on shallot vegetative growth, endogenous IAA and shallot bulb yield. Materials and Methods: The first study analyzed three different shallot tissues (root, bulb and leaf) from five different shallot cultivars (Bima, Mentes, Pancasona, Trisula and Maja). The second study was conducted using a randomized complete block design with two factors: Bima and Trisula cultivars and five exogenous IAA concentration levels. Results: The result showed that the bulb contains the highest IAA concentration and the application of exogenous IAA did not work significantly to affect shallot vegetative growth and bulb yield. However, the application of 10 mL L–1 of exogenous IAA increased the percentage of below-ground biomass and 5 mL L–1 of exogenous IAA increased total soluble solids and firmness. Conclusion: A high concentration of exogenous IAA altered biomass partitioning and a low concentration of exogenous IAA might improve shallot bulb yield quality.
