摘　　要： 在沙培马铃薯条件下，分别比较不同温度、光照条件对根结线虫（Meloidogynespp．）在马铃薯上培养效果的影响。结果表明，温度对根结线虫的培养效果有较大的影响，南方根结线虫在马铃薯上繁殖的最适温度为24-28℃，12℃时，线虫仍可侵染，但发育十分缓慢，接种后49d调查还未能观察到线虫产卵；光照条件对根结线虫的培养效果影响无明显规律性。 The effects of light and temperature on sand culture of Meloidogyne incognita on Solanum tuberosum were studied. The results showed that the temperature had a significant influence on the culture of root-knot nematode. The most suitable culture temperature for M. incognita on S. tuberosum waa 24-28℃, but the nematode could only infect and develop very slowly at 12℃ since no egg masses could be found at 49 days after inoculation. There was no close relationship between the light and nematode culture effect.
