Interaction of Nitrogen Supply and Soil Water Stress on Photosynthesis and Transpiration in Rice
Nitrogen supply Oryza sativa L Photosynthesis Rice Stomata Water stress Water use efficiency
2009/8/6
The purpose of this study is to determine if there is an interaction of nitrogen nutrition and water stress on apparent photosynthesis (APS), transpiration (Tr), and water-use efficiency in rice (Oryz...
Root Morphological Plasticity for Heterogeneous Phosphorus Supply in Zea mays L.
Nutrient patches Phenotypic plasticity Phosphorus uptake Resource foraging Root proliferation Soil heterogeneity Zea mays
2009/7/24
The morphological plasticity of roots in nutrient-enriched patches of soil is regarded as an adaptive response in plants, but its functional efficiency is still debatable. We examined whether the effi...
Susceptibility to Coolness at the Young Microspore Stage under High Nitrogen Supply in Rice (Oryza Sativa L.). Proteome Analysis of Mature Anthers
Cool temperature High nitrogen Pollen germination Proteome analysis Sterility Two-dimensional polyacrylamide gel electrophoresis
2009/7/24
In vitro pollen germination experiment using agar plates showed that the growth under high nitrogen conditions enhanced the damage to pollen germination ability caused by the cooling at the young micr...
Growth of Rice (Oryza sativa L.) Cultivars under Upland Conditions with Different Levels of Water Supply
Deep roots Lysimeter Minirhizotron Rice (Oryza sativa L.) Soil water depletion Upland
2009/7/23
A deep root system may be a desirable plant characteristic in upland rice because it improves the plant's water extraction capacity. The objective of the present study was to assess the deep root deve...
Effects of Assimilate Supply and High Temperature during Grain-Filling Period on the Occurrence of Various Types of Chalky Kernels in Rice Plants (Oryza sativa L.)
Assimilate supply Chalky kernels Grain filling High temperature Milky white kernels Rice
2009/7/23
The objective of this study was to clarify the effect of assimilate supply and high temperature on the occurrence of chalky kernels, i.e. milky white, white back, basal white and white belly kernels. ...
Shortage of Assimilate Supply to Grain Increases the Proportion of Milky White Rice Kernels under High Temperatures
Grain High temperature Milky white rice kernel Rice Spikelet filling percentage
2009/7/9
Increase in the proportion of milky white rice kernels (MWK) has seriously affected rice quality in west Japan during the last half-decade. Rising of temperature has been considered to be the primary ...
