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...
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...
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...
