Disclosed herein is a torenia plant which has large globose form flowers and single color flower petals with vivid red purple and vivid red purple floral tube. The method comprises determining whether a dimmer is present in the circuit; in response to detecting that a dimmer is present, determining a zero-crossing of the power supply and setting a bleeder current through the ballast in dependence on the phase of the power supply within a mains half-cycle; and in response to determining that a dimmer is not present, disabling the bleeder current. When a rotational force applied to the casing is smaller than an engaging force between the retaining section of the casing and a retaining device that is attached between the retaining section and the retainer, the retainer and the rod are turned to thereby turn the fastener. Based on a reproduction signal evaluation value obtained using these units and a predetermined reference value, a drive condition is determined which is suitable for recording onto the magnetic recording medium 2. In addition, forward and reverse primers and hybridization probes derived from these nucleotide sequences that are used in nucleotide detection methods to detect the presence of the bacterium are disclosed.
