Other claims from this paper (15)
- Intervention effect Soil nickel with nematode inoculation caused substantial growth reduction of tomato.
- Intervention effect Nickel at 200 or 400 mg/L caused browning or necrosis of tomato foliage.
- Intervention effect Nickel decreased root and shoot growth of tomato.
- Intervention effect Nickel decreased carotenoid and chlorophyll contents of tomato foliage.
- Intervention effect Nematodes decreased carotenoid and chlorophyll contents of tomato foliage.
- Intervention effect Nickel at 50 or 100 mg/L increased nematode disease severity (galling) on tomato.
- Intervention effect Soil nickel at 50 mg/L increased nematode reproduction and soil population of Meloidogyne incognita.
- Intervention effect Nickel at 200 and 400 mg/L decreased the number of galls, egg masses and fecundity of Meloidogyne incognita on tomato.
- Intervention effect Nickel at 200 and 400 mg/L decreased the soil population of Meloidogyne incognita.
- Intervention effect Nickel contents of roots, stems and foliage were greater in nematode-infected tomato plants than in uninfected plants.
- Observation Nickel accumulation in tomato followed the order root, leaves, stem in both infected and uninfected plants.
- Association A small increase in root Ni concentration was associated with increased juvenile penetration and gall formation of nematodes on tomato.
- Intervention effect Further increases of Ni in tomato roots suppressed nematode pathogenesis.
- Association The interaction of Meloidogyne incognita and Ni was synergistic for dry matter of tomato organs at 50 mg/L.
- Association The interaction of Meloidogyne incognita and Ni was antagonistic at 400 mg Ni for the effect on nematodes and tomato growth.
