Associative Effect of Mixed Cultures of Azotobacter and Different Rhizosphere Fungi with Rhizobium japonicum on Nodulation and Symbiotic Nitrogen Fixation of Soybean

Effect of a Microbial Inoculant on Stomatal Response of Maize Leaves

“…Actinomyces and Streptomyces produce auxins and similar substances (Purushothaman et al, 1974;Mahmoud et al, 1984), gibberellins (Arshad and Frankenberger, 1992), and cytokinins (Bermudez de Castro et al, 1977;Henson and Wheeler, 1977). Some fungi like Aspergillus niger also produce gibberellins (El-Bahrawy, 1983). The promotion of stomatal responses by intact and excised leaves of EM-treated plants is likely due to the effects of plant growth regulators existing in the liquid phase of the cultures.…”
