Other claims from this paper (16)
- Method / resource The average NRMSE between WinRhizo (LM mode) and Image-Pro Plus for root diameter was 5.44%.
- Method / resource The average NRMSE between WinRhizo (T200 mode) and Image-Pro Plus for root diameter was 10.95%.
- Observation The diameter range of fine lateral root was 0.03-0.10 mm in all experiments.
- Observation Coarse lateral roots were 0.10-0.30 mm in diameter for V1 (Nipponbare) and V2 (Wuxiangjing 14).
- Observation Adventitious roots were 0.30-1.40 mm in diameter for V1 (Nipponbare) and V2 (Wuxiangjing 14).
- Observation Coarse lateral roots were 0.10-0.25 mm in diameter for V3 (Yangdao 6).
- Observation Adventitious roots were 0.25-1.65 mm in diameter for V3 (Yangdao 6).
- Method / resource The NRMSEs for adventitious root length measured by WinRhizo and Image-Pro Plus were 10.78-12.01%.
- Observation All root indices increased rapidly during growth and reached or approached the maximum at heading, then increased slowly or decreased after heading.
- Intervention effect There were significant differences between nitrogen rate treatments from tillering to maturing on all root indices.
- Intervention effect Increasing nitrogen rate accelerated the growth of rice roots.
- Intervention effect Properly controlled irrigation promoted growth of rice roots.
- Intervention effect Properly controlled irrigation increased the proportion of lateral roots.
- Observation All root indices of V3 were significantly higher than those of the other cultivars.
- Observation There were no significant differences between V1 and V2 in root indices.
- Method / resource The authors conclude that WinRhizo with different modes can feasibly measure morphological indices of different rice root types with good accuracy and reliability.
