Abstract

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.
