在温室条件下，研究了红光诱导番茄植株对根结线虫的系统抗性。结果表明，红光照射2周和3周的番茄幼苗对根结线虫的抗性显著高于白光对照幼苗(p=0.05)。这表现在接种后30d，处理植株的根瘤数量比对照植株少。根癌指数(GI)红光处理为2.77，对照为5。红光处理根鲜重和干重分别为5.00 g和0.39 g，而白光对照分别为6.31 g和0.64 g。与对照的123.66只J2相比，进入红光处理植株根部的第二期幼虫(J2)显著减少(55只)。关键词：诱导抗性，根结线虫，红光，番茄。
This study was conducted to evaluate efficiency of red light to induce systemic resistance in tomato plants grown in 1kg plastic pots under green house conditions against Meloidogyne spp. Results indicated that tomato seedlings exposed to red light for 2 and 3wks were significantly (p=0.05) more resistant to the root knot nematodes than seedlings exposed to white light (control seedlings). This was manifested by the less number of galls on the roots of treated compared with control plants 30d after inoculation. Root gall index(gi) was 2.77 for red light treated and 5 for control plants. Root fresh and dry weight was 5.00 and 0.39 g for red light treatment compared with 6.31 and 0.64 g for white light control treatment respectively. Significantly (p=0.05) less (55) second stage juveniles (J2) enter the roots of red light treated plants compared to 123.66 J2 in control. Keywords: Induced resistance, Meloidogyne spp, Red light, Tomato.
