Analysis on Root System Morphology in Rice with Reference to Varietal Differences at Ripening Stage
Nodal roots 0ryza sativa L Root depth index Root distribution Root length Root weight
2009/7/28
The morphology of the rice root system was established by analyzing varietal differences. Four rice varieties, Koshihikari, Dobashi 1, IR36 and Lemont, were grown in an experimental paddy under ordina...
Changes in Maximum Viscosity of Wheat Flour and the Relationship to climatic Conditions during Ripening
α-Amylase activity Calendar day Maximum viscosity Mean air temperature Precipitation Sunshine time
2009/7/28
In order to study the relationship between climatic conditions and maximum viscosity (MV) in wheat flour, changes in MV and α-amylase activity by calendar day were investigated. Two winter and two spr...

Effect of Foliar Application of Triacontanol on Growth and Yield of Rice Plants:IV. Effect of triacontanol on the ripening of rice plants under shading and low temperature conditions
Foliar application Grain weight increase Low temperature Rice plants Ripening Shading Triacontanol
2009/7/27
The effects of foliar application of triacontanol (TRIA; 10ppb) on the ripening of rice were investigated under the condition of shading after heading and of low temperature before heading. The shadin...
Analysis of Plant Characteristics Determining Ear Weight Increase during the Ripening Period in Rice (0ryza sativa L.) : II. The role of the reserved carbohydrate at heading stage upon the receptive efficiency of assimilation products in spikelets
Buffer stock Ear weight increase Hull weight Paddy rice Percentage of fertile grains
2009/7/27
The large variations of sink capacity of spikelets (SW), the assimilate reserved in the culm/leaf sheath of rice plant until the heading stage (C) and the assimilate produced during the ripening perio...
Analysis of Plant Characteristics Determining Ear Weight Increase during the Ripening Process in Rice (Oryza sativa L.) : I. Plant characteristics determining the sink capacity of spikelets
Culm length Paddy rice Panicle number Percentage of productive tillers Sink capacity of spikelets Tiller number at maximum tillering stage
2009/7/24
The research was conducted to analyze the relationships between sink capacity expressed by hull weight per hill (SW) and culm length (CL) and weight of hulls per panicle (hW, ). hW and CL were adopted...
Interaction of Scion and Stock on Leaf Senescence of Soybean Plants Grafted at Mid-Stem during Ripening
Graft Photosynthetic rate Scion Senescence Soybean Stock
2009/7/24
Leaf senescence is slower in the soybean cultivar Tachinagaha (T) than in the cultivar Enrei (E). Reciprocal grafting of the two cultivars at the basal node showed that this difference was related to...
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-...
