Abstract
A study was made on the influence of combinations of photoperiods and environmental temperatures upon symbiosis betweenTrifolium glomeratum (cluster clover) andRhizobium trifolii in environment controlled growth cabinets. Experiments were done by growing plants in unsterilized soil and also in agar slopes under bacteriologically controlled conditions. Initial nodalation was delayed as the day length was increased. Photoperiods influenced not only the development of plants but also the formation, size and number of nodules on the root system.
