马铃薯植物在盆中生长，并充分浇水或水胁迫;接受这两种处理的植物中的一半被Globodera rostoclziensis感染。线虫感染的影响是相似的水分胁迫的线虫感染和水分胁迫的植物都有较小的茎-根比相比，未感染和良好浇水的植物。线虫感染和水分胁迫导致块茎产量下降，特别是在组合;总P，K和Mg的吸收也减少。线虫感染和水分胁迫的不同之处在于，在线虫感染的植物中，Ca吸收增加，但在水分胁迫的植物中，Ca吸收比充分浇水的植物少。
Potato plants were grown in pots and were either well-watered or water-stressed; half of the plants receiving each of these two treatments were infected with Globodera rostoclziensis. The effects of nematode infection were similar to those of water stress in that nematode infected and water stressed plants both had smaller shootlroot ratios when compared with uninfected and well watered plants. Nematode infection and water stress resulted in decreased tuber production, especially in combination; total P, K and Mg uptakes were also decreased. Nematode infection and water stress differed in that Ca uptake was increased in nematode infected plants but was less in water stressed plants than well watered plants.
