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...
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...
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...
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...
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...
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...
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...
We clarified that the degrees of the difference in color between outside and inside half-leaves were unexpectedly large, which ranged from 1.3 to 5.4 values by the Minolta chlorophyll meter SPAD-502 (...
Estimation of Leaf Area Index in Crop Canopies using Plant Canopy Analyzer.
We measured stomatal frequency and guard cell length in the Gramineae and compared these components among the photosynthetic types and/or the subfamilies. The mean stomatal frequency of the Eragrostoi...
Rice cv. Koshihikari was seeded and grown for three years. Seedlings were dissected under a stereoscopic microscope for anatomical studies at the following stages; in n.1 age when the (n+1)-th lamina...
Although many studies have shown cultivar differences in photosynthetic response to water deficit, the understanding of detailed mechanisms is not sufficient. We examined the mechanisms of water stres...
In a field plot where rice seedlings were planted as a single per hill, a difference of one leaf appeared in the total leaf number of the main shoot. Therefore, the main shoot with 'n' leaves and thos...
The influence of potassium (K) deficiency on leaf water and osmotic potentials, and concentrations of major solutes was determined to assess their contributions to the leaf growth of soybean plants gr...
