Model Analysis of the Determination of Leaf, Spikelet and Floret Primordium Number on Main Stem of Japanese Spring Type Wheat in the Southwestern Part of Japan
Wheat Floret Spikelet SEM Rate of initiation Model
2009/7/9
Primordium initiation on the main stem of field-grown Japanese spring type wheat was studied with a scanning electron microscope to quantify the process determining the number of leaves, spikelets an...
Effects of Spikelet Removal on Dark Respiration and Dry-Matter Production in Rice
Dark respiration Rice Low radiation Growth efficiency Ripening stage Translocation
2009/7/9
The reduction of the dark respiration at the ripening stage may increase the dry-matter production and yield in rice. The effects of spikelet removal on dark respiration and dry-matter production were...
Nodal difference in spikelet fertility and grain ripening on the panicles of cold-tolerant and-susceptible rice cultivars
Rice plants Cool-weather tolerance Grain position Secondary rachis-branch
2009/7/9
We examined the nodal distribution of the numbers of ripened and empty grains and the grain weight in the panicle in 12 rice cultivars with different cold tolerancecultivated in cool water(daily mea...
Effects of High Temperature and High Humidity during the Flowering Period on Spikelet Fertility in Japonica Rice
High temperature–induced spikelet sterility Relative humidity Pollination Japonica rice Varietal difference
2009/7/8
The varietal differences in the effects of high temperature and high humidity on the spikelet fertility of japonica rice cultivars were investigated. We constructed an apparatus that could control air...
Variation in the Determination of Leaf, Spikelet and Floret Number on the Main Stem of Wheat with Sowing Dates
Primordium formation Wheat Floret Spikelet Leaf Model Growing degree–days
2009/7/8
Variation in the number of leaves, spikelets and florets formed on the main stem in three Japanese wheat cultivars grown in the field with three different sowing dates were analyzed with respect to t...
Correlation of Nodal Position of Spikelet in Panicle and Date of Anthesis with the Grain Ripening of Rice
Primary rachis-branch Rice Date of anthesis Dry matter production Nodal position
2009/7/7
In this study the correlation of grain weight with the date of anthesis and the nodal position of glumaceous flower was analyzed. The weight growth of grains on both the primary (PR) and secondary ra...
Specific Spikelet Fertility as an Indicator of Cold Tolerance Identification at Booting Stage in Rice
