Synergistic Effect of Indole Acetic Acid and Gibberellic Acid on Mung Bean Grown under Sandy Soil Conditions

Mohamed Farouk El Karamany, Mervat Shamoon Sadak and Bakry Ahmed Bakry

Abstract:
Background and Objective: Mung bean is an important pulse food and is commonly used in cooking using green and mature pods. Plant growth regulators (PGRs) are known to influence plant growth and development at very low amounts. Thus, this investigation was done to study the synergistic role of IAA and GA3 on growth, some biochemical aspects and yield of mung bean. Materials and Methods: A field experiment was carried out in Researches and Production Station of National Research Centre, Al-Nubaria district, Al Beheira Governorate, Egypt, at two summer seasons. Seeds of mung bean were soaked for 12 h in different concentrations of bio regulator indole acetic acid (IAA) and/or gibberellic acid (GA3) with different concentrations. The experiment design was complete randomized block design in three replicates. Results: Data indicated that all treatments caused significant increases in morphological criteria, biochemical parameters and yield of mung bean plants. IAA or GA3 with 50 mg L1 concentration recorded the best values growth photosynthetic pigments as well as, endogenous auxins, GA3 and cytokinins. Interaction of IAA 50 mg L1+GA3 50 mg L1 gave the most effective treatment. The superiority of treatment IAA 50, GA3 50 mg L1 and interaction of IAA 50 mg L1+GA3 50 mg L1 recorded the same trend due to yield and yield components in characters plant height, pods No./plant, pods weight/plant, seeds No./pod, seed yield, straw yield, biological yield, total carbohydrates, protein in seeds (%) and N in seeds (%). Conclusion: It could be concluded that soaking of mung bean seeds in different concentrations of IAA and/or GA3 increased growth and yield of mungbean. About 50 mg L1 IAA+50 mg L1 GA3 was the most effective treatment on increasing growth and yield of mung bean.
