The dry weight of each organ including root in topsoil, root density in each soil layer and root morphology of rice plant (Oryza sativa L.) were compared among USA cultivars, semi-dwarf (panicle weigh...
Effect of Field Drainage on Root Lodging Tolerance in Direct-Sown Rice in Flooded Paddy Field
Direct-sown rice cultivation Field drainage Irrigation management Pushing resistance Rice Root Root-lodging tolerance
2009/7/29
To elucidate the effect of drainage of paddy fields on root lodging tolerance in direct-sown rice, we measured the pushing resistance (R), diameter of hill at the base (Dm), shoot dry weight (Ws) and ...

The relationship between biomass of an individual hill and pushing resistance was investigated using lodging tolerant US. rice cultivar 'Lemont' and suscestible Japanese rice cultivar 'Nipponbare'. T...
The Correlation of the Resistance to Root Lodging with Growth Angle, Diameter and Pulling Strength of Crown Roots in Rice Seedlings
Oryza sativa L Pushing resistance Crown root Root lodging resistance Growth angle
2009/7/9
Twenty typical Indica and Japonica rice varieties were tested for resistance to root lodging using a push-pull gauge for two years. Pushing resistance varied from 0.56 N to 2.57 N among the 20 varieti...
Correlation between Root Lodging Resistance and Breaking Resistance at the Basal Part of Rice Seedlings
