Abstract: In this study, we collected native aromatic rice cultivars from north, east and northeast of Afghanistan, and check cultivars from Japan, Thailand and India. We characterized some important...
A Quick Seeding Test for Allelopathic Potential of Bangladesh Rice Cultivars
Allelopathy Bangladesh rice Barnyardgrass Cress Donor-receiver bioassay Echinochloa colonum Lettuce
2009/7/20
The allelopathic potential of 102 Bangladesh rice cultivars (60 traditional and 42 high yielding) against four test plant species, cress (Lepidium sativum L.), lettuce (Lactuca sativa L.), barnyardgra...
Effects of Stepwise Raising of the Water Level on Increasing Tiller Number in Rice Plants (Oryza sativa L.)
Deep-irrigation Flooded depth Growth control Increase rate of tiller number
2009/7/16
Effects of stepwise raising of the water level on tiller emergence in rice were examined. When the plant age counted by leaf number on the main stem was 7.5, the plants were submerged to the level of ...
Comparison of the Yield of Direct-sowed Paddy Rice and Conventionally Transplanted Paddy Rice Cultivated Using
Azolla Chinese milk vetch Conventional transplanting culture or paddy rice Direct sowing of paddy rice into puddled and leveled soil
2009/7/16
A field trial was conducted to establish an economic and environment-conservative rice culture. The yields of the direct-sowed paddy rice cultivated using Chinese milk vetch (Astragalus sinicus L.) a...
A Mutant RM109 of Rice (Oryza sativa L.) Exhibiting Altered Lateral Root Intiation and Gravitropism
2,4-D resistance Gravitropism Lateral root Mutant Oryza sativa L
2009/7/16
We screened a large population of rice (Oryza sativa L., cv. Oochikara) M2 seeds treated with NaN3 to select mutants resistant to exogenously applied 2, 4Dichlorophenoxyacetic acid (2, 4-D). A resist...
Introduction of Low Temperature Germinability into Highly Palatable Cultivars of Rice
Direct sowing High palatability Low temperature germinability Rice
2009/7/16
In order to breed highly palatable cultivars suitable for direct sowing in rice, we tried to incorporate the genes for low-temperature-germinability into highly palatable Japanese cultivars and selec...
Influence of Nitrogen Application on Anther Length, Anther Width and Number of Engorged Pollen Grains as Characters Related to Cooling Injury in Rice Plants
Anther legth Anther width Basally applied nitrogen Cooling injury Cooling tolerance Number of engorged pollen grains
2009/7/16
Anther length, anther width, and number of engorged pollens were reported to have a relationship to cooling injury of rice. The effects of nitrogen application on anther size and number of pollens wer...
A Proxy Analysis of Nonstructural Carbohydrate in Rice Plant by Using the Gravimetric Method
Calorimetric analysis Concentration of all warmer soluble substrate (NSCWS) Concentration of reducing sugar equivalent to glucose (NSCGL) Gravimetric analysis
2009/7/16
To develop a rapid determination of nonstructural carbohydrate (NSC) in rice plant, the availability of gravimetric analysis was examined. A plant sample of 0.5 g in 30 mL of distilled water was heat...
Differentiation and Development of the Branching of Panicle with Reference to the Number of Spikelets in Rice
Branch Indica cultivar Japonica cultivar Oryza sativa L. Panicle Rice Spikelet
2009/7/16
The developmental process of young panicles was observed to estimate the diameters of young panicle primordium and the diameters of primary branch primordium. The effects of these diameters on the bra...
Branching Structure of Panicle with Reference to the Number of Spikelets in Rice
