One of the major projects being implemented by the International Rice Research Institute (IRRI), in partnership with the Chinese Academy of Agricultural Sciences (CAAS), concerns developing "Green Sup...
Tillering Behavior in Oryza sativa L:V. Analysis of varietal differences in tillering patterns
Growth Growth analysis Relative rate Synchronous growth Tiller Tiller number Tillering
2009/8/6
In our previous papers, we reported methods of growth analysis in relation to the tillering behavior of a rice plant. Using these methods, we analyzed tillering patterns of 6 rice cultivars, Akihikari...
Varietal Difference in Yield Response to Delayed Sowing Dates in Spring Wheat of Hokkaido
CGR Ear weight type German variety Growth duration Hokkaido variety Sowing date Spikelet initiation
2009/8/4
Three spring wheat varieties, old tall Haruhikari and modern semi-dwarf Haruyutaka bred in Hokkaido, and tall late Selpek bred in Germany, were sown at a 5cm equi-distant square pattern on 3 sowing da...
Varietal Difference in Morphology and Photosynthetically Active Radiation Distribution in Spring Wheat Canopy
Canopy structure Crop ideotype PAR penetration Sowing time Spring wheat variety
2009/8/4
It has been generally believed that the crop ideotype canopy has an erect small leaves to allow the photosynthetically active radiation (PAR) to penetrate deeply. In wheat, this might be not always ap...
Varietal Differences in Growth Response of Soybean to Soil Moisture Depletion
Drought tolerance Dry matter production Grain yield Pre-dawn leaf xylem water potential Root system
2009/7/29
Crop plants suffer water deficits when soil moisture is depleted significantly throughout the rhizosphere and even when only surface soil moisture decreases rapidly after they have been grown under h...
Varietal Differences in the Responses of Yield Components 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 components
2009/7/28
Grain yield of rice plants is composed of different yield components that vary with the genotype, environmental condition and cultivation practice. Experiments were conducted in 1999, 2000 and 2001 in...
Grain Filling Mechanisms in Spring Wheat : V. Evaluation of varietal differences in plant growth and assimilate accumulation with grain filling phases
Culm elongation Grain filling duration Grain filling phase Grain growth rate
2009/7/27
A regression analysis was conducted on four grain filling phases to evaluate differences in plant growth and assimilate accumulation in spring wheat varieties. Three varieties, early semi-dwarf Haruy...
