部分发展中国家马铃薯纺锤块茎类病毒病情况调查

Survey on Potato Spindle Tuber Viroid in Some Developing Countries

马铃薯类病毒病是威胁世界马铃薯生产的主要病害之一,更影响着发展中国家马铃薯产业的发展。2008~2010年,黑龙江省农业科学院植物脱毒苗木研究所连续3年举办了马铃薯病害检测技术国际培训班,对部分发展中国家从事马铃薯工作的人员进行培训,在培训过程中进行了马铃薯类病毒方面的问卷调查,调查结果显示：这些发展中国家对马铃薯纺锤块茎类病毒比较了解,发病较重的国家不多,但总体检测水平不高,甚至不进行马铃薯类病毒的检测,多数国家不重视马铃薯纺锤块茎类病毒病的防治工作。因此,马铃薯纺锤块茎类病毒病是发展中国家的隐患。

Potato spindle tuber viroid is one of the main diseases which threaten the potato production,especially in developing countries.During 2008-2010,the Virus-free Seedling Research Institute of Heilongjiang Academy of Agricultural Sciences held a series of training courses on potato disease detection techniques for developing countries.A questionnaire was designed in these three training courses.The investigation showed that developing countries knew potato spindle tuber viroid（PSTVd） very well,although PSTVd was not very serious in these countries.The detection techniques on PSTVd were not advanced in general and some of the countries even did not detect PSTVd at all.At the same time,most of these developing countries did not pay much attention to PSTVd control.Therefore,PSTVd may be a potential danger in developing countries.
