Leaf area duration Net assimilation rate Rice SPAD Total dry weight
2010/3/4
Rice yield is reduced by a short period of water stress at the early panicle-development stage. This study was conducted to examine the factors that reduce the panicle dry weight of rice subjected to ...
Comparison of Susceptibility to Photoinhibition and Energy Partitioning of Absorbed Light in Photosystem II in Flag Leaves of Two Rice (Oryza sativa L.) Cultivars that Differ in Their Responses to Nitrogen-Deficiency
Chlorophyll fluorescence Energy partitioning Hydrogen peroxide Nitrogen-deficiency Photoinhibition Photoprotection Photosynthesis Rice (Oryza sativa L.)
2010/3/4
The energy partitioning in photosystem II (PSII) and the susceptibility to photoinhibition in PSII were investigated in flag leaves of two rice cultivars, Shirobeniya (a traditional japonica) and Aken...
Stay-Green in Rice (Oryza sativa L.) of Drought-Prone Areas in Desiccated Soils
Drought Grain-filling period Rice Seedling period Stay-green
2010/3/4
Stay-green in the post-anthesis period is thought to be an efficient drought-tolerance trait in crops, but its effectiveness in rice (Oryza sativa L.) is unknown. Our objectives were to determine whet...
Growth Response of Rice (Oryza sativa L.) to Drought:I. Varietal difference in growth rate, nitrogen uptake and tillering habit at vegetative stage
Drought resistance Growth analysis Nitrogen uptake Plant type Rice Tillering habit
2009/8/6
Varietal differences in growth response to drought were studied in order to determine major attributes composing drought resistance in the rice plant. Eight rice varieties of different hydrological b...
