Figure 1From: A simple method to evaluate the number of bradyrhizobia on soybean seeds and its implication on inoculant quality control Direct plate countof B. japonicum. Direct plate count of B. japonicum strain 61A273 recovered from non-sterilized and inoculated (dose: 3 ml.kg-1) soybean seeds. Photography illustrates the colony types of bradyrhizobia cells (1) and several non-bradyrhizobia cells (2) recovered from the 10-4 dilution and inoculated into the YEM and PV-YEM media as described in material and methods.Back to article page
