Ecophysiological Studies on the Drought Resistance of Soybean:II. Effect of soil water deficit on leaf wilting and changes in photosynthesis and bleeding influenced by re-watering
Bleeding Drought resistance Leaf wilting Photosynthesis Root respiration
2009/7/30
The influence of non-watering and re-watering treatment to leaf wilting, photosynthesis, root respiration and bleeding in three cultivars (cv. Hwangkeumkong, Danyeobkong and Enrei) were investigated ...
Analysis of Factors Concerning Bleeding Rate from the Basal Part of Stem in Rice Plants
Bleeding Rice Root respiration Temperature quotient
2009/7/29
The measurement of bleeding from the basal part of the stem had been applied to estimation for root activity of rice. However, the bleeding rate (BL) showed wide variation among test plants. We invest...
Relationship between Root Respiration and Silica : Calcium Ratio and Ammonium Concentration in Bleeding Sap from Stem in Rice Plants during the Ripening Stage
Ammonium Bleeding Calcium Rice Root respiration
2009/7/29
Rice plants were given various treatments, such as organic matter application, a large amount of nitrogen as topdressing and light shading of 75%, and ammonium (NH3), silica (SiO2) and calcium (Ca) in...
Diurnal and Phenological Changes in the Rate of Nitrogen Transportation Monitored by Bleeding in Field-Grown Rice Plants (Oryza sativa L.)

2009/7/23
Nitrogen uptake is essential for rice growth and yield. Thus, the development of a simple and rapid method for monitoring nitrogen absorption is strongly required. We examined the fundamental properti...
Studies on the Varietal Difference in the Characters of High-yielding Rice:Varietal difference in bleeding rate
Bleeding rate High yielding ability Percentage of ripened grain Phytomer Rice
2009/7/15
The varietal difference in bleeding rate was investigated using 10 Japanese varieties(J group)and 10 high-yielding varieties of rice bred in Asian countries(H group). The relationship between bleeding...
Diurnal Changes in Mineral Composition of Xylem Sap and Bleeding Rate at Harvest Stage in Pepper and Melon Cultivated by Drip Irrigation under Desert Condition in Baja California, Mexico
Bleeding rate Capsium annuum L Cucumis melo L Desert Mexico Root Soil temperature Xylem sap
2009/7/15
A project to improve the crop production in arid area is underway in Guerrero Negro, Baja California, Mexico as a joint enterprise of Japanese and Mexican Government. The objective of this project is ...
Bleeding Rate of Field-Grown Maize with Reference to Root System Development
Bleeding rate Diurnal change Maize Nodal root Root Root system
2009/7/15
Bleeding rate could be an effective index for the physiological activity of a whole root system in field-grown crops, because it is based on active water absorption caused by root pressure. We examine...
Studies on the Low-temperature Damage in Rice Seedlings : Effect of low temperature on the growth arid bleeding rates of the root(Crop Morphology)
Bleeding rate Indica type Japonica type Low temperature damage Nursery period
2009/7/15
In Hunan Province in China, where double cropping of Indica rice is common, low-temperature damage on seedlings during the nursery period becomes a main problem in the first cropping. We examined the ...
Diurnal and Phenological Changes of Bleeding Rate in Lowland Rice Plants(Crop Physiology and Cell Biology)
Bleeding rate Developmental stage Diurnal change Oryza saliva L Phytomer
2009/7/10
The bleeding rate of rice plants grown in the farmer's paddy field was examined for use as an index of root activity. The bleeding rate started to decrease immediately after removing the shoot of rice...
Factors Affecting the Bleeding Rate from the Basal Part Cut End of Stem in Soybean (Glycine max (L.) Merr.) Seedlings
Bleeding rate Glycine max (L.) Merr Respiration rate Root physiological activity
2009/7/9
The bleeding rate from the stem cut end is considered to reflect the root physiological activity since the bleeding is caused by the active water absorption by root. We analyzed factors affecting the ...
