Other claims from this paper (9)
- Observation In the glasshouse, both potato cultivars showed similar gas exchange, leaf water potential and leaf xylem ABA concentration under well watered or water deficit conditions.
- Observation In the glasshouse, shoot biomass was similar in both potato cultivars under well watered or water deficit conditions.
- Association Under well watered conditions, root growth was three-fold higher in Horizon than in Maris Piper 3 weeks after emergence.
- Association Water deficit reduced the root-growth difference between Horizon and Maris Piper.
- Intervention effect In the polytunnel, applying 60% or less irrigation volume significantly decreased tuber yield in Maris Piper.
- Association Horizon had higher root density than Maris Piper in deep soil layers where water content was stable.
- Recommendation Early vigorous root proliferation may be a useful selection trait for maintaining potato yield under restricted irrigation or rainfall.
- Recommendation Selecting for vigorous root growth may assist phenotyping screening for drought tolerance in potato.
- Recommendation Potato varieties may need particular environmental or cultural conditions to express root vigour.
