Effects of Top Dressing on Growth and Panicle Dry Weight as Affected by Soil Water Stress at the Early Panicle-Development Stage in Rice (Oryza sativa L.)
Leaf area duration Net assimilation rate Rice SPAD Total dry weight
2010/3/4
Rice yield is reduced by a short period of water stress at the early panicle-development stage. This study was conducted to examine the factors that reduce the panicle dry weight of rice subjected to ...
Two Distinct Growth Types for Number of Developed Leaves, Heading Time, Culm and Panicle Lengths, and Internode Length within Near-isogenic Lines of Rice
breeding cultivation uniformity
2009/9/9
There are two growth types of plants for the number of developed leaves, heading time, and culm and panicle lengths within a population of a homozygous rice cultivar. However, this phenomenon has not ...
Scanning Electron Microscopic Observations on Morphogenesis of the Panicle and Spikelet in Rice Plants
Anther cuticle Apical meristem Morphogenesis Panicle Rice plant Scanning electron microscope
2009/8/6
Morphogenesis of panicle and spikelet in paddy rice, cultivars Yuhkara and Fujihikari was studied by SEM. Germinated seeds planted in containers with submerged soil were cultured under natural condit...
Characteristics of Dry Matter Production Process in High Yielding Rice Varieties:IV. Dry matter accumulation in the panicle
Dry matter production Harvest index High yielding variety Reserve carbohydrate Rice plant
2009/8/6
In order to clarify the characteristics of high yielding rice varieties, total dry matter production, yield and harvest index were compared in 1988 and 1989 among the two early and three medium variet...
Changes of Heading Time and Panicle Weight in Rice Subjected to Water Stress during the Early Stage of Panicle Development
Cumulative water stress Heading time Leaf water potential Panicle weight Rice
2009/8/6
The increase of heading time in proportion to cumulative water stress (an integrated estimate of the degree and duration of water stress) was demonstrated in a wetland rice cultivar Koshihikari subjec...
Sterile Spikelets of Rice Plants Induced by Low Temperature in 1988:Difference in heading date among stems and spikelet locations on the panicle
Heading date Main stem Rice plants Spikelet locations on the panicle Sterility Susceptibility to low temperature
2009/8/6
A large number of sterile spikelets were induced by low-temperature at the booting stage of rice plants during the middle to the end of July in 1988. The authors investigated various aspects of occur...
Relation of Number of Spikelets per Panicle to the Characteristics of Shoot and the Size around Growing Point at Panicle Initiation Stage in Rice Varieties
Internode diameter Number of differentiated spikelets Number of spikelets per panicle Rice
2009/8/5
The relationships between number of spikelets per panicle and the characters of shoot and the size around growing point at panicle initiation stage were studied with the rice varieties bearing much d...
Developmental Change in Panicle Water Potential in Rice
Leaf water potential Panicle water potential Rice
2009/8/4
Rice panicles start to transpire just after heading. We can therefore expect that the water potential of panicles changes little prior to heading and varies in response to transpiration after heading...
Relationship between Panicle Weight per Plant and Cumulative Water Stress in Rice
Cumulative water stress Heading and anthesis Leaf water potential Panicle weight per plant
2009/7/31
Decrease of panicle weight per plant in rice in proportion to cumulative water stress (an integrated estimate of the degree and duration of water stress) has been demonstrated in rice subjected to inc...
Changes of Water Potential in Rice Panicle under Increasing Drought Stress at Various Stages
Drought Panicle development Rice Water potential Water stress
2009/7/31
Experiments were conducted to examine whether the responses in panicle water potential under drought changes with panicle development. Twenty seedlings of two rice cultivars, Norin 20 and Milyang 23, ...
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...
Varietal Difference in the Effects of Applied Gibberellic Acid (GA3) on the Number of Spikelets per Panicle in Rice Plants
GA3 Gibberellic acid application Internode diameter Number of spikelets per panicle Rice Varietal difference
2009/7/31
Eight rice varieties were grown in pots and the varietal difference in the effects of applied gibberellic acid (GA3) on the number of spikelets per panicle were examined. GA3 (5 ppm) was sprayed onto ...
