The relationships between the tolerance to cool temperature in the booting stage and the grain quality of paddy rice in Hokkaido.
Effects of Pre-Flowering Soil Moisture Deficits on Dry Matter Production and Ecophysiological Characteristics in Soybean Plants under Drought Conditions during Grain Filling
Dry matter production Photosynthesis Root system development Senescence
2009/7/31
Summer crop plants grown in rain-fed fields suffer from drought during a hot and relatively dry summer after the rainy season called "Baiu" in Japan. Since crop plants might develop vigorous shoots wi...
Difference in Grain Productivity of Tillers among Main Stem Nodes in Rice Plant : II. Comparison under the conditions of the same panicle number and constituent of each order tiller per plant
Each order tiller Leaf blade elongation rate Leaf emergence rate Nodal position on main stem Rice plant
2009/7/31
Tillering of the 2nd to 11th main stem nodes in potted directed-seeded rice plants was artificially controlled by the removal of tillers on specific nodes. Treatments consisted of limiting tillering o...
Cultivar Differences in Leaf Photosynthesis and Grain Yield of Wheat under Soil Water Deficit Conditions
Cultivar difference Drought Grain yield Photosynthesis Soil water deficit
2009/7/30
Cultivar differences in leaf photosynthesis (LPS) and grain yield of wheat [Triticum aestivum L.] were examined under irrigated and non irrigated conditions in Cerrados, a semi-arid region in Brazil. ...
Grain Filling Mechanisms in Spring Wheat:III. Effects of shadings on dry matter accumulation in grain and culm
Dry matter accumulation rate Dry matter partitioning Grain filling phase Regression analysis
2009/7/30
To determine the effects of assimilate shortage to grain filling mechanisms in spring wheat canopy (cv. Haruyutaka), we examined the accumulation and translocation of dry matter in grain, along with w...
Grain Filling Mechanisms in Spring Wheat : II. Growth, accumulation and translocation in the daytime and at night during the four grain filling phases
Daytime and night time Grain filling phase Quantitative assessment of growth Regression analysis Spring wheat
2009/7/30
The dry weights and water soluble sugar contents (WSC) in grain, ear, culm and leaves of the field grown spring wheat (cv. Haruyutaka) were measured every morning and evening throughout the grain fill...
Studies on Grain and Flour Quality of Wheat in the Tohoku District : 2. Effect of grain size on wheat quality
Brabender Grain size Koyukikomugi Milling Quality Wheat
2009/7/30
The relationships between grain size and quality in wheat were investigated with Koyukikomugi from 1989 to 1991. In 1990/1991 experiment, Koyukikomugi was harvested at maturity by combine, and grains ...
Studies on Agronomic Traits of African Rice (Oryza glaberrima Steud.):III. Some grain morphological aspects of domestication and decrement

2009/7/29
To identify some characteristics of Oryza glaberrima in grain morphology, length (L), width (W) and thickness (T) of unhusked grain were determined for two cultivated species, i.e. O.sativa and O.glab...
Yield of Several Grain Crops Grown after Early-season Rice of Northern Kyushu
Early-season culture Grain crop Short-term rotation Solar energy utilization
2009/7/29
No grain crops are usually grown after harvesting early-season rice of northern Kyushu. If early maturing crops could be cultured after the rice harvest of mid August, more solar energy could be captu...
