Other claims from this paper (19)
- Observation Grapevine fine root extension peaked in the afternoon and two hours after darkness at 0.15–0.38 mm per hour.
- Observation Grapevine root growth declined overnight to a morning minimum.
- Observation Diurnal root growth dynamics occurred across genotypes, which differed in growth level.
- Association Root growth correlated positively with temperature under naturally fluctuating conditions.
- Observation Diurnal root growth persisted under a typical photoperiod regardless of constant or increased temperature.
- Intervention effect Maximum root extension declined when soil temperature rose to about 31 °C.
- Association Shoot growth rate rose in the higher temperature zone.
- Observation Reduced diurnal root growth fluctuation persisted in continuous darkness.
- Association Genotype was a dominant influence on average root length.
- Association Soil temperature was a main influence on average root length and growth rate.
- Association Vertical root distribution in the field varied by genotype.
- Observation 140 Ruggeri roots were concentrated at 10 cm to 60 cm.
- Observation Ramsey roots were concentrated at 20 cm to 40 cm.
- Observation Schwarzmann roots were concentrated at 10 cm and 40 cm.
- Observation Shiraz roots were concentrated at 20 cm to 60 cm.
- Observation Root numbers ranked 140 Ruggeri highest, followed by Ramsey and Schwarzmann, with Shiraz lowest.
- Observation New root flushes occurred around bud break, peaked at flowering and were lowest after harvest.
- Observation Some grapevine root growth continued in winter during shoot dormancy.
- Association Seasonal root growth dynamics were significantly related to air temperature, developmental stage and genotype.
