Heliotropic movement Leaf inclination angle Leaf xylem water potential Light intensity on leaf surface Soybean
2009/7/31
To clarify the effect of light on the trifoliolate compound leaf movement in the soybean plant, (1)changes in the area of the triangle described by the three tips of the leaflets (ΔT) and leaf inclina...
Relationship between Leaf Movement of Trifoliolate Compound Leaf and Environmental Factors in the Soybean Canopy : II. Effects of growth and environmental conditions on diurnal changes of leaf movement
Diurnal change Growth stage Heliotropic leaf movement Leaf inclination angle Leaf position Soil water deficit Soybean Trifoliolate compound leaf
2009/7/30
We previously reported a method for measuring trifoliolate compound leaf movement in the soybean plant. Leaflet movement was investigated by measuring the area of triangle described by the three leafl...
Photosynthetic Control Factors in a Single Leaf of Sweet Potato, Ipomoea batatas Lam : 3. Estimation of in vivo rubisco activity from the CO2 exchange rate of a peeled leaf
CO2 exchange rate Ipomoea batatas Lam Leaf epidermis peeling Rubisco activity
2009/7/30
Rubisco (ribulose 1, 5-bisphosphate carboxylase/oxygenase) activity is the prime determinant for CO2 exchang rate (CER) at the beginning of the photosynthetic reaction, and hence the rubisco activity ...
Relationship between Leaf Movement of Trifoliolate Compound Leaf and Environmental Factors in the Soybean Canopy:I. Measurement of leaf movement
Heliotropic leaf movement Leaf inclination angle Nyctinastic leaf movement Soybean Trifoliolate compound leaf
2009/7/30
The occurrence of leaf movements during the daytime is widely known in the leguminous plant canopy. We observed in the soybean field that leaflets moved not independently but that the trifoliolate com...
Analysis of Factors Concerning Bleeding Rate from the Basal Part of Stem in Rice Plants
