Phytohormonal Activity of Immobilized Cells of Salt-Tolerant Cotton Rhizobacteria After Long Term Storage

Abstract


 
 
 The phytohormonal activity of free and immobilized cells of B. subtilis BS-80, B. licheniformis BL-83, P. polymyxa PP-113 and P. amylolyticus PA-118 on phosphate flour have been studied. It was found that immobilized cells more actively synthesized IAA and gibberellins in comparison with free cells. The data obtained indicates that the phytohormonal activity of the salt-resistant cells of cotton rhizobacteria can be kept much better in the immobilized form than in the free form (in a refrigerator on jambs).
