    Notes: Abstract Wild type (Rif−) and rifampicin resistant (Rif+) isolates of fluorescent Pseudomonads were grown in King’s B liquid medium in the presence and absence of iron and subcultured every 48 h for 12 days. Growth rates and the proportion of non-fluorescent colonies were measured. All Rif+ isolates when grown in the presence of iron produced a significantly higher proportion of non-fluorescent colonies. One Rif+ isolate had a reduced growth rate.

    Notes: Abstract The colonisation of a radish root system by strains ofPseudomonas fluorescens, selected for their ability to promote potato and radish growth under different environmental conditions is reported. In pot experiments colonisation of different parts of the root system was measured at different temperatures, in different watering regimes and in sterile and recropped soil. Root colonisation was extensive but populations were highest on the upper root system and their distribution throughout the root system was greatly affected by environmental factors. percolation of water through the soil and partial soil sterilisation enhanced colonisation but the effects of temperature and recropping were complex. Growth promotion was unpredictable and there was no simple relationship between PGPR colonisation and stimulation of plant growth.

    Notes: Abstract Methods are described for measuring the colonisation of a radish (Raphanus sativus) root system by seedlings with rifampicin resistant fluorescent pseudomonads by dilution plating, and which would take account of differences in root morphology. Differences in the levels of pseudomonad colonisation was highly dependent on the units in which surface areas was expressed. Population levels are expressed using estimates of surface area based on root length, tap-root length and root weight. The best estimate of surface area was root length, but the most practical method was surface area calculated as a function of dry weight. This method could differentiate differences in the levels of root colonisation independent of differences in root morphology and was efficient enough to allow the routine processing of a large number of replicate root samples.
