Genotypic Variation in Ability to Recover from Weed Competition at Early Vegetative Stage in Upland Rice
Improved cultivar Laos Recover from weed competition Slash-and-burn Traditional cultivar Upland rice
2010/3/4
In northern Laos, weeds are a major constraint to upland rice production in slash-and-burn systems. Two experiments were conducted to assess genotypic variation in ability to recover from weed competi...
Genotypic Variation in Responses of Cassava (Manihot esculenta Crantz) to Drought and Rewatering: Root System Development
Cassava Drought Drought recovery Lateral roots Plasticity Principal component analysis
2010/3/4
Soil moisture condition is a major factor that affects root system development and thus, crop production. This study aimed to evaluate genotypic variations of cassava in root system structures and the...
Effects of Light Quality, Daylength and Periodic Temperature Variation on the Growth of Lettuce and Radish Plants
Daylength Lettuce Light quality Radish R/B ratio R/F ratio Thermoperiodicity
2009/8/6
Effects of light qualities under continuous lighting, daylengths at a constant temperature, and periodic temperature variations under continuous lighting on the vegetative growth of lettuce and radish...
Variation of 2-Acetyl-1-Pyrroline Concentration in Aromatic Rice Grains Collected in the Same Region in Japan and Factors Affecting Its Concentration
Aromatic rice Harvest time Oryza sativa L 2-Acetyl-1-pyrroline Temperature Variation
2009/7/28
Aroma strength of aromatic rice varies with the genetic and environmental conditions. We determined the concentration of 2-acetyl-1-pyrroline (2AP), a key compound of the aroma of aromatic rice, in 62...
Genotypic Variation of the Ability of Root to Penetrate Hard Soil Layers among Japanese Wheat Cultivars
Breeding materials Genetic variation Hard soil Penetrating ability of root Screening Soil compaction Triticum aestivum L. Wheat
2009/7/23
The hard soil in the field is a major constraint for the cereal production because it mechanically restricts the root expansion and water absorption. The ability of root to penetrate into the hard soi...
Variation in Growth and Yield Performance of Seventeen Water Chestnut Accessions (Trapa spp.) Collected from Asia and Europe
Aquatic plant Paddy field cropping Trapa Water chestnut Yield
2009/7/23
Water chestnut is an aquatic annual herb, and its fresh, edible fruit is a valuable crop. The huge variation in growth and yield of water chestnuts has not been well documented. In this study, the yie...
Genotypic Variation of Stomatal Conductance in Relation to Stomatal Density and Length in Rice (Oryza sativa L.)
Rice (Oryza sativa L.) Rice diverse research set of germplasm (RDRS) Specific stomatal conductance Stomatal conductance Stomatal density Stomatal length
2009/7/23
Stomatal conductance (gs) is an important trait responsible for the genotypic difference in gas diffusion for photosynthesis and transpiration in rice (Oryza sativa L.). We measured gs, stomatal densi...
Specific Variation in Shoot Growth and Root Traits under Waterlogging Conditions of the Seedlings of Tribe Triticeae Including Mizutakamoji (Agropyron humidum)
Adventitious roots Agropyron humidum Branching roots Elymus humidus Flooding Triticeae Waterlogging Wheat
2009/7/23
Waterlogging stress is an important limiting factor for wheat and barley production. Waterlogging tolerance was evaluated in the seedlings of seven species from the tribe Triticeae, including wheat, b...
Method of Estimating the Variation of Growth Stages on the Basis of the Regularity of Morphogenesis in Rice Plants
Critical stages of cool temperature Development model Developmental stage Flowering date Glumous flowers Growth variation Mature stage
2009/7/8
We modified the development model established for early warning of cool-weather damage to estimate the percentage of productive panicles and glumous flowers at a specific stage such as meiosis, in th...
