Stimulation of Seed Germination and Growth Parameters of Rice var. Sahbhagi by Enterobacter cloacae in the Presence of Ammonium Sulphate as Substitute of ACC

Abstract

Plant growth-promoting rhizobacteria (PGPR) with 1-aminocyclopropane-1-carboxylate deaminase (ACCD) activity facilitate the improvement of agricultural productivity and yield stability. The present work reports the efficiency of Enterobacter cloacae with ACCD activity isolated from an organic farm near SHUATS, Allahabad, India. This PGPR was screened for stimulation of seed germination and growth promotion of the rice var. Sahbhagi in the presence of ammonium sulphate as a substitute of 1-aminocyclopropane-1-carboxylate (ACC). Inoculation of rice var. Sahbhagi with the PGPR showed a significant (p < 0.01) increase in seed germination and enhancement in elongation of root and shoot compared to untreated control. Potential efficacy of E. cloacae (KP226569) to enhance the growth of rice will be discussed.
