Two separate effects of Inabenfide on the formation of branch roots in rice plants (Oryza sativa L.) were investigated, using a special apparatus constructed with a Wagner pot (1/2000 a) divided into ...
In a rice embryo sac, there is an antipodal mass located at the opposite side of the micropyle, directly adjoining nucellar cells. Immediately after anthesis, the antipodal cells are characterized by...
Before anthesis, rice antipodal cells are located between nucellar cells and a central cell, and have a large-sized lobed nucleus and many cell-wall ingrowths abutting the nucellar cells. An outstandi...
To examine the factors affecting the emergence and establishment of rice seedlings, we tested FAO-designated germ plasm 207 cultivars (indica rice 137 cultivars, japonica rice 56 cultivars, and unexp...
No-tillage direct seeding of rice (Oryza sativa L.) in early spring was conducted to disperse seeding work and to improve heading time in cold regions. Germinated seeds were seeded every 5 days in 19...
The purpose of this study was to discuss the practical usefulness of the discrimination of indica and japonica cultivar groups based on the morphology of silica bodies from motor cells in rice (Oryza ...
The effects of an irregular density of seedling establishments in direct seeding cultivation of rice (Oryza sativa L.) on growth and grain yield and their relations were investigated in a paddy field...
We investigated the relationship between the forms of emergence and the seedling growth of rice(Oryza sativa L.)and the effects of plant growth regulators on the forms of emergence and seedling growth...
The growth characteristics of hill-seeded rice were compared with those of broadcast-seeded rice to establish the submerged direct seeding cultivation using a newly developed 'Shooting hill-seeder'. ...
The relationship between drought resistance and deep root system was examined using eight Japanese upland rice and one lowland rice variety with medium to late maturing cultivated in the upland field ...
Field trials were conducted to evaluate the effects of vacant hills on growth and yield characteristics of rice (Oryza sativa L.) under several cultural conditions. In side dressing of readily availa...
To understand the responses of flag leaf shape in rice to elevated CO2 environment and their genetic characteristics, quantitative trait loci (QTLs) for flag leaf shape in rice were mapped onto the mo...
