The objective of this series is to investigate the relationships between root lodging tolerance and root characteristics of rice (Oryza sativa L.). In this paper, the pushing resistance was measured i...
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...
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...
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...
For breeding rice with a high root-lodging resistance, which is important for direct seeding in subnerged paddy fields, selection of cultivars at the seedling stage is preferable. Twenty typical Ind...
