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...
Flag Leaf Number Determination of Secondary and Tertiary Tillers and Heading Characteristics of Rice Plants
Flag leaf number Heading date Main culm Rice plant Sheath wrapping Tillers
2009/8/6
When the number of leaves on the main culm is known, the number of leaves on secondary to quarternary tillers can be determined based on the following growth characteristics and procedures, even if th...
Difference of Photosynthetic Rates among the Leaves at the Equivalent Positions on the Main Stem and Its Tillers in Rice Plants
Main stem Paddy rice Photosynthetic rate Synchronously expanded leaf Tiller Varietal difference
2009/8/6
The photosynthetic rates of the leaves at the equivalent positions on the main stem and its tillers, that is, the photosynthetic rates among the synchronously expanded leaves on the main stem and till...
Relationship between Main Stem and Primary Tillers in the Position of Lowest Elongated Internode of Deepwater Rice
Deepwater rice Elongation ability Internode elongation LEI NNEI Rice Stem growth
2009/8/6
One of the deepwater rice (Oryza sativa L.), cultivar. 'Habiganj Aman VIII' was used as materials. Elongation ability of deepwater rice is closely related to the phase change of the main stem from th...
Character Expression of the Semidwarfing Gene sd-1 in Rice (Oryza sativa L.):II. Appearance and development of tillers
Near isogenic line Nitrogen fertilizer Rice (Oryza sativa L.) Semidwarfing gene Tiller development
2009/8/6
Gene expression in tiller development by the semidwarfing gene sd-1 was studied under two different nitrogen levels. A Japonica tall variety Norin 29, its semidwarfing near isogenic line SC-TN 1, and ...
Growth and Grain Yield of Wheat in Relation to Differences in Soil Groups:II. The emergence and survival of tillers and their contribution to yield
Adaptability to low phosphoric-acid concentration Andosol Gary Lowland Soil Number of spikes
2009/8/5
The emergence and survival of tillers and their contribution to yield of three varieties, Asakazekomugi, Norin 61 and Norin 64, were examined in four different soils to find the limiting factors to gr...
Analysis of Developmental Phase of Stem in High Nodal-Position Tillers in Rice Plants
Developmental phase Elongated internode High nodal-position tillers Non-elongated internode
2009/8/4
One of the japonica paddy rice (Oryza sativa L. 'Sasanishiki') was used as a material. The panicles were cut off when all of their tillers had completed headings so that the new shoots (NS), namely, ...
Studies on Growth and Development of Tillers in Wheat : II. Reexamination of the emergence of tillers from the developmental relationships of leaves and roots
Emergence Environmental conditions Leaf Root Tiller Wheat
2009/8/4
In this study, the relationships between the emergence of tillers and the plant development, the emergence of leaves and roots were examined. Winter wheat (Triticum aestivum L.) plants, cv. Norin 61 g...
Studies on Growth and Development of Tillers in Wheat:I. Analyses of the morphological features by principal component analysis method
Environmental condition Principal component analysis Size Tiller number Wheat
2009/8/4
Wheat (Triticum aestivum L.) yields often are closely related to the sowing rate and the number of tillers on a plant. This study was conducted to examine the morphological features of whole plant and...
Effects of Seeding Density on the Frost Damage of Wheat Tillers
Compensation Frost damage Grain yield Nitrogen Potassium Seeding density Tiller Wheat
2009/8/4
Degrees of frost damage were observed for three varieties of winter wheat at the different seeding densities. Shoot nitrogen, phosphorus, potassium, sugars and starch contents were measured at the int...
