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 ...
Tillering Behavior in Oryza sativa L:V. Analysis of varietal differences in tillering patterns
Growth Growth analysis Relative rate Synchronous growth Tiller Tiller number Tillering
2009/8/6
In our previous papers, we reported methods of growth analysis in relation to the tillering behavior of a rice plant. Using these methods, we analyzed tillering patterns of 6 rice cultivars, Akihikari...
Tillering Behavior in Oryza sativa L:IV. Effects of temperature on the tillering behavior
Growth Growth analysis Relative tiller position Synchronous growth Temperature Tiller Tillering
2009/8/6
In the previous three papers, we have obtained the methods of growth analysis about the tillering behavior of a rice plant. Using the methods, the temperature effects were investigated in the present ...
Tillering Behavior in Oryza sativa L:III. The pattern and the relative rate of increase in tiller number
Exponential curve Growth analysis Growth curve Logistic curve Relative rate Synchronous growth Tiller
2009/8/6
The properties of the growth curves of the tiller number per plant in case of the single-planted rice plants in a pot culture were investigated. The tiller number increased with time, and the pattern ...
Tillering Behavior in Oryza sativa L.:VIII. Relationship between the tillering position on the stem and the final leaf number of each tiller
Flag leaf Nodal position of tiller Number of leaves Relative leaf position Relative tiller position
2009/8/6
Using two types of nodal position of tiller development (counted acropetally from base and basipetally from panicle), relationships between the nodal position of tiller development and the final numbe...
Effects of Inabenfide on the Growth of Roots in Rice Plants (Oryza sativa L.)
Branch root Growth regulator Inabenfide Rice (Oryza sativa L.) Root system Shortening of culm length
2009/8/4
Effects of Inabenfide (SERITARD), a gibberellin biosynthesis inhibitor, on root growth of rice plants was examined in main stems of cv. 'Reiho' grown under field cndition in 1989 and per hill and per ...
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 ...
Studies on Heading Characteristics of Primary and Secondary Tillers in Rice(Oryza sativa L.) : I. Influence of leaf cutting on heading characteristics of primary and secondary tillers
Delayed heading Heading date Leaf cutting treatment Main stem Panicle initiation
2009/7/31
The purpose of this experiment was to identify the cause of the differences in the heading date and the time of panicle differentiation among individual tillers in a plant. Three varieties, Norin 1, N...
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...
Comparison of Water Use Efficiency of Paddy Rice (Oryza sativa L.) among Locations and Interannual Variation in Humid Areas : 1. Reliability of estimated canopy transpiration rate from meteorological and physiological data of the crop
Canopy resistance Evapotranspiration Leaf area index Penman-Monteith method Rice Stomatal conductance
2009/7/29
