Other claims from this paper (10)
- Association Root system growth was influenced by the interaction of temperature and photoperiod.
- Observation Maximum shoot growth at 20°C occurred under a 24-h photoperiod.
- Observation Maximum shoot growth at 5°C occurred under a 16-h photoperiod.
- Association Maximum shoot growth correlated with a high root:shoot ratio in both temperature treatments.
- Intervention effect Short photoperiod and low temperature delayed new adventitious root production.
- Intervention effect Short photoperiod induced frost tolerance in existing roots.
- Intervention effect Low temperature alone did not decrease root dry-weight accumulation.
- Intervention effect Cold temperature retarded developmental processes within roots.
- Intervention effect At 5°C, first-order lateral roots developed more slowly than at 20°C.
- Intervention effect At 5°C, endodermal wall suberization was slower than at 20°C.
