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 ...
Male Sterility Caused by Cooling Treatment at the Young Microspore Stage in Rice Plants:XXX. Relation between fertilization and the number of engorged pollen grains among spikelets cooled at different pollen developmental stages
Anther Cool injury Cool temperature Microspore Pollen Rice Sterility
2009/8/6
Cooling treatments at different stages of pollen development lowered the percentage of fertilized spikelets through decreasing the number of engorged pollen grains per anther at anthesis. Cooling duri...
Flag Leaf Number Determination of Secondary and Tertiary Tillers and Heading Characteristics of Rice Plants
Flag leaf number Heading date Main culm Rice plant Sheath wrapping Tillers
2009/8/6
When the number of leaves on the main culm is known, the number of leaves on secondary to quarternary tillers can be determined based on the following growth characteristics and procedures, even if th...
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...
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...

Paddy field cropping Planting density Transplanting time Trapa bispinosa Roxb
2009/8/4
The yield performance of water chestnut plants cultivated in paddy fields under conditions of varying combinations of time and density of transplanting was investigated with reference to the change of...
The Effect of Shading at Different Growing Stage on the Spike Number and the Character of Spike in Wheat Plants
Fertile spikelet number Floret differentiation Grain number per spikelet Grain weight Shading treatment Spikelet number Sterile spikelet number Tiller
2009/8/4
The effect of shading at different growing stage on wheat was examined to confirm the stage when the spike number and the character of spike were determined. Spike number decreased by shading to full...
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...
