Varietal Differences in Photosynthetic Rates in Rice Plants,with Special Reference to the Nitrogen Content of Leaves
Nitrogen content Photosynthetic rate Rice variety Rubisco content Stomatal conductance
2010/3/4
The photosynthetic rate in the flag leaf of rice at the full heading stage was examined in three japonica varieties, Koshihikari, Aikoku and Asanohikari, and the indica high-yielding variety Takanari ...
Varietal Differences of Juvenile Phase Duration and Photoperiodic Sensitivity in Paddy Rice
Cropping area Juvenile phase Paddy rice Photoperiodic sensitivity Varieties
2009/8/6
The juvenile phase and photoperiodic sensitivity of 13 Japanese paddy rice varieties were investigated. The duration of juvenile phase was determined by counting the days of insensitivity to a short-d...

Varietal Differences in Tillering and Yield Responses of Rice Plants to Nitrogen-Free Basal Dressing Accompanied with Sparse Planting Density in the Tohoku Region of Japan
Nitrogen-free basal dressing Rice cultivars Sparse planting density Weather conditions Yield
2009/7/28
At present, the main challenge in rice production is to achieve a high and stable yield with low input. In this study, the growth of tillers and yield of 12 rice cultivars and lines in the practice of...
Temporal and Spatial Variations of Carbohydrate Content in Rice Leaf Sheath and Their Varietal Differences
Carbohydrate Enzyme Leaf sheath Spatial variation Temporal change Variety
2009/7/27
In rice plant, carbohydrates accumulated in leaf sheaths before heading are translocated to grain and affect yield formation greatly. To clarify the intrinsic mechanism of carbohydrate metabolism in t...
