Three early wheat cultivars of west Japan, Norin 26, Norin 61 and Omasekomugi, sown in autumn, were compared regarding tiller appearance and heading. The difference in maximum tiller number among thre...
Effect of Water Potential of Culture Medium on Geotropic Response of Primary Seminal Root in Japanese Wheat Cultivars
Geotropic response Primary seminal root Triticum aestivum Water potential
2009/8/4
It has been observed that wheat has a shallow root system in wet soil and a deep root system in dry soil. However, the control mechanisms of root growth depending on soil water status remain unclear. ...
Relationship between Root Growth Angle of Seedlings and Vertical Distribution of Roots in the Field in Wheat Cultivars
Cultivar Root Root depth index (RDI) Root growth angle Seminal root Vertical distribution of roots
2009/8/4
Vertical distribution of roots is known to influence environmental stress tolerance of crops. To estimate the genotypic characteristic on the vertical distribution of roots in the field, the growth an...
