High Temperature-Induced Spikelet Sterility of Japonica Rice at Flowering in Relation to Air Temperature, Humidity and Wind Velocity Conditions
Flowering stage High temperature Japonica rice Pollination Spikelet sterility
2009/7/23
Although the impact of anticipated global warming on regional rice production merits intensive investigation, quantitative information regarding the effects of high temperatures on japonica rice is li...
Effects of Day Length and Air Temperature on Stem Growth and Flowering in Sesame
Flowering Growth Sesame Short day length Temperature
2009/7/23
The effects of day length and air temperature on the growth and flowering of sesame (Sesamum indicum L.) were examined to analyze the effect of seeding date on the seed yield. Short day (10-h light/14...
A System for the Measurement of Vertical Gradients of CO2,H2O and Air Temperature within and above the Canopy of Plant
CO2 profile Gradient system H2O concentration Light intensity
2009/7/21
This technical report describes a gradient system for characterizing the vertical gradients of CO2, H2O, and air temperature within and above the canopy of plants. The system is low in cost and easy t...
Relation between Mean Air Temperature during Ripening Period of Rice and Amylographic Characteristics or Cooking Quality
Amylographic characteristics Cooking quality Mean air temperature Specific gravity Water temperature
2009/7/16
Studies on the relationship between mean air temperature during the ripening period and amylographic characteristics or cooking quality of rice were examined. There was a highly positive correlation b...
Effects of High Air Temperature in Summer of 1999 on Ripening and Grain Quality of Rice
Apparent quality Eating Quality High air temperature Rice Ripening Solar radiation
2009/7/15
Although rice yield in 1999 was no less than the normal value, high air temperature during the 1999 summer season damaged the apparent quality of rice kernels in a large area of Japan. The percentage ...
Effect of Air Temperature during the Early Grain-filling Stage on Grain Fissuring in Rice
Grain filling Grain fissuring Meteorological condition Rice Temperature
2009/7/9
We conducted field and pot experiments to elucidate the effect of meteorological conditions during grain filling on grain fissuring in rice. A total of 13 cultivars were grown in paddy fields in 1997...
Modeling of Translocation Rate of Dry Matter from Vegetative Organs to Panicle as Influenced by Air Temperature in Rice
Air temperature Air temperature difference Model Rice
2009/7/8
Field experiments were carried out at 8 sites: Chiang Mai and Ubon in Thailand, Taoyuan of Yunnan and Nanjing in China and Kitakami, Ina, Kyoto and Matsue in Japan, to clarify the relationship between...
Difference between Canopy Temperature and Air Temperature as a Criterion for Drought Avoidance in Upland Rice Varieties under Field Conditions in Japan
Canopy surface temperature Deep-rooted Drought avoidance Drought resistance Infrared thermometry Thermal image Thermography
2009/7/8
The difference (ΔT) between canopy temperature (Tc) and air temperature (Ta) was examined for its validity as a criterion for drought avoidance in upland rice under field conditions in Japan, where va...
Effects of High Air Temperature during the Ripening Period on the Grain Quality of Rice in Warm Regions of Japan
High temperature Husked rice quality Palatability Varietal difference White-back kernel
2009/7/7
Influence of high temperature conditions during the ripening period of paddy rice on husked rice quality was examined. The incidences of white-back kernel and white-based kernel were high when averag...
