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...
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 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 ...
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...
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...
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...
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...
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...
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...
The branching structure of the panicles of eight japonica and eight indica cultivars was compared after estimating the number and position of the differentiated branches and spikelets. The secondary a...
Dry matter production and the determination mechanism of the number of spikelets of the semidwarf indica rice cultivar, Takanari, were examined in comparison with those of the standard japonica cultiv...
Morphological and Anatomical Analysis on the Formation of Crown Root Primordia of Rice Plant.
Direct-seeding culture without tillage and covering soil using the Y-shaped seeding furrow was examined in 1997 and 1998 at a poorly drained paddy field in Hachirogata(Akita Pref., Japan). The percen...
The effect of fluorine(HF)added to the irrigation water at 0, 5, 10, 20, 30, 50 and 100 ppm under the soil culture on the growth of Oryza sativa L.(cv. Koshihikari)was investigated. The effects of lea...
In 1995, Chiba Prefectural Agricultural Experiment Station bred a new paddy rice cultivar "Fusaotome" which is tolerant to cool weather, early maturing(same as "Hananomai"), and has high grain-quality...
