Studies on Transplanting Injury in Rice Plant:III. Effects of root pruning treatment on the organic constituents in each organ and rooting of seedlings after transplanting
Carbohydrate content Early growth Nitrogen content Paddy rice Rooting Root pruning Tillering
2009/8/6
This study was undertaken to clarify the effects of root pruning on the organic constituents and early growth in each organ of seedling after transplanting, using 6 leaf aged seedlings without prunin...
A Basic Study on Field Experiment and Investigation Methods in Rice Plant:III. Precision of some sampling methods in sample survey of quantitative characters
Coefficient of variation Field experiment Quantitative character Rice plant Sampling method
2009/8/5
In sample survey on field experiment, samples have to be sampled at random in principle, but samples are often taken systematically due to restriction of time, labor and plot area. In order to get inf...
A Basic Study on Field Experiment and Investigation Methods in Rice Plant : IV. A dry weight survey method effective in laborsaving while maintaining precision
Double sampling Dry weight Field experiment Precision Ratio estimate Rice plant Sample survey
2009/7/31
Dry weight of rice plant is an important character for the vegetative diagnosis and growth forcast of this plant. However, it requires a long time and much labor to precisely estimate the dry weight, ...
Difference in Grain Productivity of Tillers among Main Stem Nodes in Rice Plant : II. Comparison under the conditions of the same panicle number and constituent of each order tiller per plant
Each order tiller Leaf blade elongation rate Leaf emergence rate Nodal position on main stem Rice plant
2009/7/31
Tillering of the 2nd to 11th main stem nodes in potted directed-seeded rice plants was artificially controlled by the removal of tillers on specific nodes. Treatments consisted of limiting tillering o...
Depression of Photosynthesis in Rice Plant with Low Root Activity Following Soluble Starch Application to the Soil
Initial Rubisco carboxylation activity Photosynthesis Rice plant Rubisco content Root activity Soluble starch
2009/7/30
Soluble starch was applied to soil in a pot where rice plant grew at the 10th leaf stage and the initial heading stage. When root activity and leaf bleeding rate were lowered in the treated plant, ph...
A Basic Study on Field Experiment and Investigation Methods in Rice Plant:V. A leaf area survey method effective in laborsaving while maintaining precision
Double sampling Field experiment Leaf area Precision Ratio estimate Rice plant Sample survey
2009/7/30
Leaf area of rice plant is an important character for survey to elucidate its characteristics of dry matter production. However, it requires much time and labor to precisely estimate the leaf area, w...
Morphological Studies on the Regularity of Shoot Development in Rice Plant : V. The regular modification in changes of organ length on main shoot with the same total leaf number
Growth Growth type Internode Leaf Oryza sativa L Rice plant Shoot development
2009/7/27
In a field plot where rice seedlings were planted as a single per hill, a difference of one leaf appeared in the total leaf number of the main shoot. Therefore, the main shoot with 'n' leaves and thos...
