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...
Growth, Yield and Photosynthetic Activity of Vigna radiata L. Grown at Different Temperature and Light Levels
Chlorophyll fluorescence Drymatter allocation Photosynthesis Pod setting Vigna radiata L.
2009/7/29
Two varieties of mungbean (Vigna radiata L.), BARImug 2 (M2) and BARImug 3 (M3) were grown under 1) 12-h light at 700 μmol m-2 s-1 (HL) at 30°C/12-h darkness at 25°C (HL+LT), 2) 12-h HL at 40°C (HT)/1...
Plant Nitrogen Levels and Photosynthesis in the Supernodulating Soybean (Glycine max L. Merr.) Cultivar ‘Sakukei 4’
Chlorophyll content Glycine max L.Merr. Nitrogen content Nitrogen fixation Nodule Photosynthesis Soybean Supernodulation
2009/7/24
Supernodulating soybeans, having several times more nodules than normal genotypes, are expected to produce higher dry matter and grain yields through a higher nitrogen fixation potential. However, the...
Effects of Anoxia on Amino Acid Levels in Rice Coleoptiles
alanine amino acid γ-aminobutyric acid anaerobiosis anoxia fructose glucose Oryza sativa L.
2009/7/24
Effects of anoxia on the levels of free-amino acids were investigated in the coleoptiles of rice (Oryza sativa L.) seedlings. Rice coleoptiles are able to grow in extremely low oxygen conditions. Anox...
Growth of Rice (Oryza sativa L.) Cultivars under Upland Conditions with Different Levels of Water Supply
Deep roots Lysimeter Minirhizotron Rice (Oryza sativa L.) Soil water depletion Upland
2009/7/23
A deep root system may be a desirable plant characteristic in upland rice because it improves the plant's water extraction capacity. The objective of the present study was to assess the deep root deve...
Relative Contributions of Tolerance and Avoidance to Drought Resistance in Dry-Matter Production of Different Rice Cultivars at Different Fertilization Levels
Cultivar difference Drought avoidance Drought resistance Drought tolerance Dry-matter production
2009/7/14
Relative contributions of drought tolerance and drought avoidance to drought resistance in the dry-matter production of different rice cultivars at different fertilization levels were evaluated based...
Salinity Levels Affecting Growth, Yield and Quality of Strawberry Grown in Peat Bags
Affecting Growth Strawberry Salinity Levels
2009/7/13
To estimate the critical salinity level of nutrient solution for strawberry (Fragaria × ananassa Duch.), ‘Nyoho’ plants were grown in peat bags (8 plants in 28 × 80 cm bags containing 18 liter of medi...
