The typical spot symptoms on fruit would decrease the production and merchandise of tomato in the heavy rain of June and July; therefore, the key period for disease control is after rainy season. Quick identification on pathogen was using PCR. 1476bp band was amplified by primer P3、P4of bacterial speck. By using primer CMM5、CMM6 for bacterial canker, 614bp fragment was amplified. These PCR tests provided important foundation for pathogen identification and disease diagnoses. Using primer RST65 and RST69 for bacterial spot, expected 420bp band was not amplified.

通过聚合酶链式反应对病原进行快速鉴定,证明加工番茄细菌性斑点病用引物P3、P4可以得到一条大小为1476bp的特异性条带,番茄细菌性溃疡用CMM5、CMM6可以扩增出一条大小为614bp的特异性条带,这为病害的快速诊断打下了基础,但利用引物RST65和RST69对番茄细菌性疮痂病进行鉴定,没有得到预期420bp的目标条带,故对细菌性疮痂病的快速检测还有待继续研究。

"When you combine the ideas of whistles at night, the presence of a band of gipsies who are on intimate terms with this old doctor, the fact that we have every reason to believe that the doctor has an interest in preventing his stepdaughter's marriage, the dying allusion to a band, and, finally, the fact that Miss Helen Stoner heard a metallic clang, which might have been caused by one of those metal bars that secured the shutters falling back into its place, I think that there is good ground to think that the mystery may be cleared along those lines."

&当你把晚间的哨声、跟这位老医生有亲密关系的那群吉卜赛人的存在、我们有充足理由相信医生有意阻止他的继女结婚的事实、弥留之际对'群伙'的暗示、最后还有,海伦小姐听到的金属当当声可能是由那些防止窗板落下的其中一根铁棍产生的事实联系起来,我想我们有很好的依据认为我们能弄清楚这个迷。&
