Single Leaf Photosynthesis of Rice Plants under Field Conditions:III. Variation in single-leaf photosynthesis with time of day and its physiological base
Degree of depression in CER Evaporation rate Leaf positions Rice plants Single-leaf photosynthesis
2009/8/6
Under field conditions, the photosynthetic rate of single leaves (CER) declined with time of day even in the case where light intensity at the leaf surface was kept higher than the saturation point. T...
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...
Time of Determination and Variations within and between Plants in Leaf Shape of Soybean
Glycine max (L.) Merr Leaflet shape Leaf shape index Soybean Variation
2009/8/4
Experiments were carried out to elucidate the time at which the leaflet shape was determined during growth, and to evaluate the extent of variation of leaf shape within and between plants in soybean. ...

The horizontal distribution of leaf temperature in a rice population of 40×40 meters was investigated with an infrared scanning thermometer under a high temperature and high solar radiation during the...
Effects of Leaf Movement on Radiation Interception in Field Grown Leguminous Crops:II. Soybean (Glycine max Merr.)
Canopy structure Heliotropic leaf movement Integrated solarimeter film Leaf temperature Radiation interception Soybean
2009/8/4
The effects of the leaf movement on radiation interception were examined by a treatment which restrained the leaf movement in the upper layers of the canopy. Two determinate soybean cultivars with dif...
Studies on Heading Characteristics of Primary and Secondary Tillers in Rice(Oryza sativa L.) : I. Influence of leaf cutting on heading characteristics of primary and secondary tillers
Delayed heading Heading date Leaf cutting treatment Main stem Panicle initiation
2009/7/31
The purpose of this experiment was to identify the cause of the differences in the heading date and the time of panicle differentiation among individual tillers in a plant. Three varieties, Norin 1, N...
Leaf Emergence Pattern of Late-maturing Cultivars in Soybeans
Leaf emergence Leaf emergence pattern Leaf emergence rate Sowing date Soybean Turning point of leaf emergence rate
2009/7/30
It is well known that there are a few turning points of leaf emergence rate on the main stem in soybean plants (Glycine max Merr.). On the other hand, it has also been reported that the leaf emergence...
A Basic Study on Field Experiment and Investigation Methods in Rice Plant:V. A leaf area survey method effective in laborsaving while maintaining precision
Double sampling Field experiment Leaf area Precision Ratio estimate Rice plant Sample survey
2009/7/30
Leaf area of rice plant is an important character for survey to elucidate its characteristics of dry matter production. However, it requires much time and labor to precisely estimate the leaf area, w...
Regularity in Variation of Leaf Color and Nitrogen Distribution in Half-leaf Blades by Leaf Position on the Stems of Rice Plants:I. Variation of chlorophyll meter values and mechanism of leaf formation
Chlorophyll meter Concordance Cultivar Half-leaf blade Leaf blade width Leaf color
2009/7/29
