Other claims from this paper (7)
- Intervention effect At 250 larvae, tomato photosynthesis was lower than in uninfected plants.
- Observation Root 14C-glucose incorporation declined only at 2,000 nematodes per plant.
- Intervention effect Root 14CO2 incorporation declined at 250 nematodes versus uninfected plants.
- Observation Root 14CO2 incorporation declined further at 1,000 nematodes.
- Observation Inoculation with 2,000 nematodes caused no further decline in 14CO2 incorporation.
- Observation The results did not support root metabolic sinks as a major driver of shoot growth.
- Observation The photosynthesis data suggested inhibited upward water and nutrient transport may be more important.
