The compatibility of strains is crucial for formulating bioinoculants that promote plant growth. We herein assessed the compatibility of four potential bioinoculants isolated from potato roots and tubers (Sphingomonas sp. T168, Streptomyces sp. R170, Streptomyces sp. R181, and Methylibium sp. R182) that were co-inoculated in order to improve plant growth. We screened these strains using biochem...

The complexity of humic substances and their remarkable properties have attracted and continue to attract the attention of many investigators, bringing over the years new knowledge on their structure, physicochemical and biological properties pointing to the use of these interesting natural compounds in many practical applications. The numerous investigations produced, up to now, controversial ...

Aim: Salt stress adversely affects plant growth and development. Various mitigating strategies have been employed to enhance the adaptability of plants salt stress. The present study was conducted with objective evaluating recently developed CO55 rice variety's ability withstand salt-induced during seedling growth. This evaluation included foliar spraying promoting substances like melatonin, sa...

It is known that yeast or plant extracts markedly stimulate the growth of the root nodule organism in media of purified ingredients. An essential growth factor or superior source of nitrogen has been invoked to explain the results, but neither theory has a broad experimental basis. The results of Allyn and Baldwin (1930) suggest that the extracts may affect favorably the oxidation-reduction pot...

Gibberellins are compounds that produce a wide variety of growth responses in flowering plants. Among these responses are stimulation of shoot growth for many plant species,' root elongation in maize,2 induction of bolting and flowering in some biennial and long-day plants,3-resumption of normal growth in certain genetically dwarfed genotypes of maize,6 growth stimulation in dwarf strains of pe...
