Streptomyces olivaceoviridis, S. rimosus and S. rochei proved to possess a high capacity for the production of auxins, gibberellins and cytokinin-like substances, together with substantial levels of alpha -amylase and proteinase. Grain priming with culture filtrates of S. olivaceoviridis, S. rimosus or S. rochei appeared to enhance growth vigor and crop yield of wheat plants. In the majority of cases, the culture filtrate of S. olivaceoviridis appeared to be the most effective in this respect. The present results are discussed in relation to the indirect role played by these bacteria in producing plant growth-regulating substances and their effects on growth and yield of wheat.
