Test the germination of seeds contain varieties of jasmine 105 and Suphanburi 60 found that rice, jasmine 105 percent germination 95% and the number of seeds that do not germinate 5% and Supanburie 60 percent germination 98% and amounted to. Seeds do not germinate at 2% and isolated spots of rice seed. The sterilized with corlox 75%, which isolated six isolates the JM-001, JM-001.1, JM-002, JM-002.2, JM-003, JM-003.3, which was characteristic colonies round embossed on it. shiny colonies had both white and yellow. And white colonies will be built phosphor. Believe the six isolates are not used in the process of inoculation. When he went to check on the infection. Step positive PCR results do not meet the requirements. Therefore infection Through technical PCR (Jewel, 2557), and seems to be inoculated seed alkalinity of rice studying with 2 isolates, including K29WS 2.4 and TS 1.1 (merit Drug, 2557), which was used in the procedure. inoculation Which will be tested on crops in the first month of using the four ways, namely (I) spraying the tree, (II) injection into the sheath, (III) use scissors to cut the leaves and then dip suspensions and bacteria. (IV) led the Clippers dip eliminates bacteria then cut leaves. It appears that the inoculation method (II) injection into the sheath, the most obvious symptom. The symptoms are evident most clearly occupies an area of inoculation. And tested in rice yield in rice and 105 Supanburie 60 results show that the hybrid rice 105 infected K29WS 2.4 Symptoms of infection of the virus into seed destroyed more severe infection ST 1.1, which see. Symptoms shown after inoculation 10 days K29WS 2.4 infection symptoms. Burning brown to black seeds dry atrophy symptoms of infection ST 1.1. Burning light brown to dark brown. The infected seeds to dry atrophy. Phase grains Supanburie 60. K29WS 2.4 symptoms on inoculated grain after the inoculation within 10 days symptoms are white medium grain seeds are dark brown. Seed, some symptoms, but the seeds are brown. The seeds were infected will look withered dry. The results are not entirely clear, the conclusion was that the bacteria damage rice, the second term is caused by not having to wait for the results of diagnostic certainty. The nature of the infection that attacks will look like. Disease spotted in rice seeds But must wait for the results conclusively proven.
