Differential Responses of Common Bean (Phaseolus vulgaris) Cultivars to Exogenous Indole-3-Butyric Acid Application
ZULKADİR GÜLAY
Bean (Phaseolus vulgaris) is a globally important legume crop valued for its nutritional content and adaptability. Establishing a robust root system during early growth is critical for optimal nutrient uptake, shoot development, and increased resistance to biotic stress. This study evaluated the effects of exogenous indole-3-butyric acid (IBA) on root and shoot development in two bean cultivars, Onceler-98 and Topcu, during the seedling stage. IBA was applied at four concentrations: 0 (control), 50, 100, and 150 μM. Morphological parameters measured included root length (RL), root fresh weight (RFW), root dry weight (RDW), root nodule number (RNN), shoot length (SL), shoot fresh weight (SFW), and shoot dry weight (SDW). The experiment followed a randomized complete block design with four r...
