e0“Cowpea ( Vigna unguiculata ) has relatively higher drought tolerance than other legume crops”
e1“There were three watering treatments, T1 (well-watered), T2 (mild water stress) and T3 (severe water stress)”
e2“Under T3, the total dry matter of TVu7778 was about one third of those of the other treatments for the same variety, whereas that of IT96D-604 was more than half”

Other claims from this paper (11)
- Observation The two cowpea varieties did not differ significantly in shoot and root characteristics, except leaf area under well-watered conditions.
- Intervention effect Under mild water stress the shoot:root ratio of IT96D-604 decreased significantly compared with well-watered plants.
- Intervention effect Under mild water stress root dry matter of IT96D-604 increased compared with well-watered plants.
- Intervention effect Under mild water stress leaf area of IT96D-604 decreased compared with well-watered plants.
- Intervention effect Under mild water stress total dry matter of IT96D-604 did not differ significantly from well-watered plants.
- Intervention effect Under severe water stress total dry matter of IT96D-604 was more than half of that under the other treatments.
- Intervention effect Under water stress the centres of root dry matter and root length density of both varieties moved downwards significantly compared with well-watered conditions.
- Association The downward root movement under water stress was more pronounced in IT96D-604 than in TVu7778.
- Association Drought tolerance of IT96D-604 was associated with an increase in root dry matter per leaf area under mild water stress.
- Association Drought tolerance of IT96D-604 was associated with downward root movement under mild and severe water stress.
- Method / resource The root-box method was versatile for studying root responses to edaphic factors.
