Combined Effect of Hill Arrangement, Wind Direction and Wind Speed on Bending Angles of Culms and Lodging Levels in Rice Plant
Bending angle Lodging level Major axis of a rice hill Rice hill Wind direction Wind speed
2009/8/6
This experiment started from the observation that the cross section of a rice hill was ellipse in shape. When two rice plants cv. Koshihikari were transplanted in a 1/2000 are Wagner pot, the rice hil...
Varietal Difference of the Cell Wall Components Affecting the Bending Stress of the Culm in Relation to the Lodging Resistance in Paddy Rice
Bending stress Cell wall component Lignin Lodging resistance Paddy rice Varietal difference
2009/8/4
We investigated which cell wall components of the culm affect the bending stress of the culm using seven rice cultivars. A small difference in the cell wall composition was noticed among the cultivars...
Analysis on the Bending Response of Rice Tillers to the Upright Position
Curvature Gravitropism Pulvinus Rice
2009/7/31
We studied how the tiller axes move toward the upright positon using one of the Japonica type rice Sasanishiki (Oryza sativa L.). In the first trials, each plant was grown in a pot. The tiller shoots...
Hydraulic Conductivity and Aquaporins of Cortical Cells in Gravitropically Bending Roots of Pisum sativum L.
Aquaporin Cell elongation Gravitropism Hydraulic conductivity Pisum sativum L. Water uptake
2009/7/27
We examined the differential elongation of gravitropically bending roots of Pisum sativum L. in terms of cell enlargement and water uptake by cells in the growing tissue. Hydraulic conductivity betwee...
Improvement of Resistance to Bending-Type Lodging in Rice
Bending-type lodging Lodging resistance Physical strength of stem Plant height
2009/7/7
Lodging is the most important problem in rice production, because it causes yield loss through poor grain filling, lowers grain quality, and lowers the efficiency of mechanical harvesting. The improve...
