Allelopathic growth stimulation of plants and microogranisms. Allelopathy Journal. 16(2): 175-198. Interpretive Summary: Abstract Only Technical Abstract: Growth promotion of plants by other plants and microorganisms as well as microorganisms by plants and other microorganisms are discussed. Agrostemma Githago in mixed culture with wheat enhances growth and yield of wheat. Tricontanol and brassinolide stimulate growth of several crop plants. Chromosaponin I and petunioside enhance plant growth and petunioside, in addition, suppresses a virus disease of cucumber. Unidentified allelochemicals from Chenopodium album and Setaria viridis enhance the growth of Bradyrhizobium japonicum. The majority of soil microbes are capable of synthesizing plant growth regulators. Addition of glucose and tryptophan as a precursor is highly conducive for microbial production of growth regulator. Azospirillum brasilense enhances root growth of inoculated pearl millet (Pennisetum americanum L.). Metabolites from a few actinomycetes stimulate growth of several crop plants. Seed inoculation with selected strains of Pseudomonas capacia and P. putida enhances growth and yield of wheat. Inoculation of soybean seeds with a strain of Bacillus cereus enhances nodulation of soybean by indigenous nodulating bacterium. Microbial metabolites enhance growth of several species of Rhizobium. These examples of allelopathic growth promotion indicate that this phenomenon has a great potential in agriculture. |
