To determine the effect of brassinolide (BR, 2α, 3α, 22R, 23R-tetrahydroxy-24S-methyl-B-homo-7-oxa-5α-cholestan-6-one) on the translocation of assimilate during the ripening of rice plants (Oryza sati...
Effects of Source-to-Sink Ratio on Carbohydrate Production and Senescence of Rice Flag Leaves during the Ripening Period
Chlorophyll Leaf senescence Nitrogen Photosynthesis Rice Rubisco Sink size Sucrose synthesis
2009/8/4
Partial removal of spikelets and partial defoliation were conducted in rice at anthesis to evaluate the effects of the source-to-sink ratio (ratio of leaf area to grain number). The ratio was 0.75 in ...
A Comparison of the Accumulation and Partitioning of Nitrogen in Plants between Two Rice Cultivars,Akenohoshi and Nipponbare,at the Ripening Stage
Leaf nitrogen content Nitrogen accumulation Nitrogen partitioning Photosynthesis Rice Senescence

Photosynthesis and Dry-Matter Production during Ripening Stage in a Female-Sterile Line of Rice
Dry-matter production Female sterility Panicle Photosynthesis Rice Sink Source
2009/7/28
The relation between the source capacity of leaves and the sink capacity of panicles affects dry-matter production and determines grain yield in rice. The source-sink relation has so far been studied ...
Dry-Matter Partitioning and Accumulation of Carbon and Nitrogen during Ripening in a Female-Sterile Line of Rice
Carbon C-N ratio Dry-matter partitioning Female sterility Nitrogen Panicle Rice
2009/7/24
To evaluate the effect of sink restriction on dry-matter partitioning to rice plant organs during ripening, we observed the dry-weight partitioning and accumulation of carbon and nitrogen in a female-...
Effects of Soil Moisture Conditions before Heading on Growth of Wheat Plants under Drought Conditions in the Ripening Stage: Insufficient Soil Moisture Conditions before Heading Render Wheat Plants More Resistant to Drought during Ripening
Drought avoidance Dry matter production Grain yield Irrigation efficiency Leaf water potential Root Soil water potential Wheat
2009/7/23
Plants growing on soil with insufficient moisture need deep and dense roots to avoid water stress. In crop plants, the production of dry matter during ripening of grains is critically important for gr...
Daytime and Nighttime Field Spectral Imagery of Ripening Paddy Rice for Determining Leaf Greenness and 1000-Grain Weight
Artificial light source Digital image Reflectance Rice SPAD 1000-grain weight
2009/7/21
A spectral-image observation technique to measure the reflectance information of rice plant organs (instead of the overall canopy) under either daylight or artificial light at night was developed, and...
Physiological Mechanisms of Poor Grain Growth in Abnormally Early Ripening Wheat Grown in West Japan
Abnormally early ripening Culm reserves Poor grain filling Remobilization Starch granules Wheat
2009/7/21
We found a symptom of abnormally early ripening in a farmer’s field in Natajima, Yamaguchi Prefecture, Japan, in 2004/2005, and examined its physiological mechanisms for two weeks until maturity. In t...
Contribution of Nitrogen Absorbed during Ripening Period to Grain Filling in a High-Yielding Rice Variety,Takanari
Grain filling High-yielding variety Nitrogen partitioning Rice Ripening period
2009/7/21
High-yielding rice varieties require a large accumulation of N in panicles. The objectives of this study were to clarify the change in N allocation during the ripening period (Exp. 1) and to quantify ...
