High-yielding Crop Management by Enhancing Growth in Reproductive Stage of Direct-Seeded Rainfed Lowland Rice (Oryza sativa L.) in Northeast Thailand
Biomass production Growth duration Nitrogen uptake Reproductive stage
2010/3/4
The crop management in direct-seeded rice to promote growth during the reproductive stage was evaluated in weed-controlled toposequentially intermediate fields in a small watershed in Northeast Thaila...
Tillering Behavior in Oryza sativa L.:VI. The tillering behavior at late tillering stage
Growth analysis Last emergence daughter tiller Relative rate Synchronous growth Tiller Tiller number Tiller position Tillering
2009/8/6
The tillering behavior of rice plants (1 plant/pot) at the late tillering stage was investigated. Assuming plant growth in which a leaf of each tiller and a leaf of the main stem expand synchronously ...
Male Sterility Caused by Cooling Treatment at the Young Microspore Stage in Rice Plants:XXXI. Four components participating in fertilization
Cooling injury Cooling tolerance Fertilization Microspore Pollen Rice
2009/8/5
We divided the developmental processes from microspore differentiation to fertilization into 4 phases and defined the component relating to fertilization in each phase. The percentage of fertilization...
Developmental Stage Estimation Method for Rice in Various Cropping Seasons and Areas
Application Cropping area Cropping season Developmental stage Estimation Rice Temperature
2009/8/4
Estimation of the developmental stages of paddy rice by temperature (DVS method) was conducted during different cropping seasons and areas for the rice variety Koshihikari. The DVS method was applied ...
Factors Affecting the Night Dark Respiration Rate of Individual Plant in the Later Growth Stage of Rice (Oryza sativa L.)
Carbohydrate Dark respiration Nitrogen Rice plant Ripening Senescence Solar radiation
2009/7/31
Variation of the specific rate of average night dark respiration (Rs-n) expressed as mgCO2 g dry wt. -1h-1 of individual plant was examined in semi-dwarf high-yielding indica, F1 hybrids and japonica ...
Sterility in Rice (Oryza Sativa L.) Subject to Drought during the Booting Stage Occurs not because of Lack of Assimilate or of Water Deficit in the Shoot but because of Dehydration of the Root Zone
Booting stage Degeneration of spikelet Dehydration Drought Oryza sativa L
2009/7/30
In rice plants a drought at the booting stage is the event most damaging to grain yield because it drastically increases sterility. Our objective was to establish what phosiological processes caused s...
Effects of Short Period Treatments at Low Temperature (9°C) on Growth of Rice Plants at the Tillering Stage
Growth Leaf blade length Leaf sheath length Low temperature Main stem Rice plant
2009/7/30
The rice plants cv. Sasanishiki (3 plants/pot) were moved into the controlled growth chamber at 9°C when half of the leaf blade (LB) of the 7th leaf (L7) was emerged (H plot) or when the whole 7th lea...
Influence of Sowing Time and Nitrogen Topdressing at the Flowering Stage on the Yield and Pod Character of Green Soybean (Glycine max (L.) Merrill)
