植物寄生线虫极大地影响着世界的菠萝生产。由于菠萝根系的不再生性,因此根的损害尤为严重,当根系受损后,作物产量明显地减少;宿根作也会受毁,造成了严重的减产。同时,母株所长出的初生根系健康与否,直接影响到吸芽的数量、大小与长势。 世界范围为害的重要的线虫种类有:短尾根腐线虫(Pratylenchus brachyurus)、爪哇根结线虫(Meioidogyne javanica)和肾脏线虫(Rotylenchulus reniformis)。在巴西和象牙海岸共和国,短尾根腐线虫是最重要的种类。在南非,短尾根腐线虫和爪哇根结线虫是优势种。爪哇根结线虫在澳大利亚是一个重要的种类,而在夏威夷则以爪哇根结线虫和肾脏线虫为主要。当然,人们还发现与菠萝根有联系的其他种类的线虫,但这些线虫的致病性还未被证实,且危害性不大。
Plant parasitic nematodes greatly affect the world’s pineapple production. Root damage is particularly severe due to the non-regenerative nature of the pineapple root system, which significantly reduces the crop yield when the root system is damaged; the root cropping operation is also destroyed, resulting in severe yield cuts. In the meantime, the primary root system grown by the mother plant is healthy or not, which has a direct impact on the quantity, size and growth of sucking buds. Important species of nematodes harbored worldwide include: Pratylenchus brachyurus, Meioidogyne javanica and Rotylenchulus reniformis. In Brazil and the Ivory Coast, Brachyura is the most important species. In South Africa, Stinkweed and Javanica are the dominant species. The root-knot nematode in Java is an important species in Australia, while in Hawaii, the root-knot nematode and nematode nematode are dominant. Of course, other species of nematodes associated with pineapple roots have also been found, but the pathogenicity of these nematodes has not yet been proven and is not as damaging.
