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...
Relationships between Changes in the Heading Date and Yield-related Traits of Sweet Sorghum (Sorghum bicolor Moench) in the Northern Area of Japan
Cumulated average temperature Dry matter yield Heading Northern area of Japan Number of elongated internode
2009/7/31
Relationships between days after sowing to heading (DAS-H) and dry matter yield of main stem, between DAS-H and dry matter yield-related traits involving total leaf number, number of elongated intern...
Effects of Elevated CO2 Concentration on Photosynthetic Carbon Metabolism in Flag-Leaf Blades of Rice before and after Heading
Elevated CO2 concentration Rice Starch Sucrose-phosphate synthase Yield
2009/7/29
We monitored the effects of elevated atmospheric CO2 concentrations on the photosynthetic carbon metabolism in the flag leaves of rice plant (Oryza sativa L. cv. Akitakomachi) before and after heading...

Effects of Soil Moisture Conditions before Heading on Growth of Wheat Plants under Drought Conditions in the Ripening Stage: Insufficient Soil Moisture Conditions before Heading Render Wheat Plants More Resistant to Drought during Ripening
Drought avoidance Dry matter production Grain yield Irrigation efficiency Leaf water potential Root Soil water potential Wheat
2009/7/23
Plants growing on soil with insufficient moisture need deep and dense roots to avoid water stress. In crop plants, the production of dry matter during ripening of grains is critically important for gr...
Effect of Transplanting Time on Growth of Rice Cultivar "Kinuhikari"in Kagawa Prefecture : Temperature effect on time of appearance of the first tiller, heading and maturation
Heading time Kinuhikari Mean temperature Number of days from heading time to maturation
2009/7/21
This experiment was carried out in order to examine the influence of transplanting time on the growth of rice plants in Kagawa Prefecture, Japan. A rice cultivar, Kinuhikari, was transplanted at 3-4 d...
Response Spectrum for Green Light-Induced Acceleration of Heading in Wheat cv. Norin 61
Green light Heading rate Response spectrum Spectral sensitivity Wheat
2009/7/20
The response spectrum for green light induced-acceleration of heading in wheat cv. Norin 61 was investigated using narrow-bandwidth (10 nm) green light within the range of 520-550 nm. Heading was obse...
Effects of Climatic Factors on Heading of Rice Cultivars in Early-Season Culture in Miyazaki Prefecture
