| | The virucide-TS (Trade mark-Zhibingling)can suppress infection ofToMV(Tomato mosaic virus)effectively.The TS of 0.5-1.0 ppm wassprayed on the infected tomato plants during early flowering,the efficierncy ofcuring was 77.7%-95.7%,and the yeild was increased by 6.7%-17.3%.Morcover,the content of chlorophyll(a+b)was raised by 18.6%,the re-duction capacity of chloroplast to light by 78%,and the activity of cyto-kinin by 174%.The results showed that there is an intimate inter-relation-ships between curing virus ... | | TS制剂能有效地阻止番茄花叶病毒(Tomato mosaic virus)对番茄的感染。对已经感病的植株,在始花期喷施0.5~1.0ppm 浓度的TS药液,治疗效果达77.7%~95.7%;产量显著增加;叶绿素含量增加18.57%;叶绿体对光还原能力增加78.0%;细胞分裂素含量提高174.1%。显示了化学治疗与促进生理效应的密切关系。 | | 文摘来源 | | A three years study on "TS" preparation controlling tobacco mosaic disease in nine iocations (among 4 counties) showes that: 1) the TS works either in the seedling stage or in field and it is working well at field condition; 2) the function of the TS increases with the spraying times; 3) triplicated using the TS drops the deseasing rate from 47. 5% to 8. 3% and the control effect reaches 77, 8%. The single leaf weight increases by 0. 73 g. The high-quality leaves reaches about 20. 4%. And all above results ... | | 本文通过三年四个县、市九个点次,对“植病灵”(TS制剂)防治烟草花叶病的效果进行了研究,结果表明:①在苗期及田间使用“植病灵”均具有良好的防病效果,以田间的防病效果为佳;②随着喷洒“植病灵”的次数增加,防病效果也随之提高;③烟草在生长期(苗期1次,田间2次)喷洒3次“植病灵”,可降低发病率39.2个百分点,防病效果达77.8。单叶重增加0.7g,上等烟叶率可达20.4%,增加产量28.4%,纯增加收入1888.5元/ha,效果显著;④全省九个试点大面积平均增产31%,平均增加收入1358.6元/ha。 | | 文摘来源 | | After spraying diseased mulberry with TS mixture,the peroxidase and polyphenol oxidase isoenzymes zymogram have been compared by polyacrylamide gel electrophoresis (PAGE).Through PAGE four polyphenol oxidase isoenzyme band are found both in treated and checked plant,but their strength has some difference.There are four peroxidase isoenzyme band in treated plant,three band in checred plant,a new peroixidase isoenzyme band in treated,their activity ha... | | 用植物病毒防治剂(TheVirocideforPlant)—TS制剂喷洒感病桑树植株后,用聚丙烯酰胺凝胶电泳对叶片多酚氧化酶、过氧化物酶进行同功酶比较,发现处理株多酚氧化酶的酶带数和对照株相同,均为4条,但酶带位置、强弱有差异;处理株过氧化物酶有4条基本酶带,而对照株有3条酶带,处理株出现一条新酶带.处理株多酚氧化酶活性感病后期比感病初期提高1.6倍,对照株酶活性提高1倍,而过氧化物酶活性感病后期比感病初期下降60%,而对照株酶活性下降80%.用紫外分光光度计测蛋白质含量,处理组为0.3g/L,对照组为0.38g/L,表明经TS制剂处理比对照桑萎缩病的病株蛋白质含量降低. | | 文摘来源 | |   |
