In order to evaluate the relationship of sink and source on seed yield and yield components of soybean (Glycine max (L.) Merrill) cultivars in Mazandaran province at different dates of sowing a split...
The time course change of the shoot respiration rate, the percentage of currently assimilated carbon in respiration and the amounts of current and reserved compounds in the shoots of rice plants were ...
In adzuki beans (Vigna angularis) the degrees of lightness, shade, and uniformity for red color of the seed coat are very important indices on estimation of seed quality in Japan. This study was condu...
Partial removal of spikelets and partial defoliation were conducted in rice at anthesis to evaluate the effects of the source-to-sink ratio (ratio of leaf area to grain number). The ratio was 0.75 in ...
Photosynthesis and root weight production in single leaf grafts were discussed from the point of view of sink-source balance. Cultivars used were Koganesengan (K), Siroyutaka (S), Beniaka (B) and Tsur...
In order to identify the key factors that arrest yield improvement in rice, we observed fifteen divergent cultivars in a field at Kyoto, Japan in 1995 and 2001 under various nitrogen (N) regimes. The ...
Water uptake of seeds and hardseededness under 27°C soaking in adzuki bean (Vigna angularis) cv. Erimo-shozu were evaluated for seedlots (a total of 544 growers) collected from four districts in Hokka...
In semi-arid areas, pearl millet is an important staple food crop that is traditionally intercropped with cowpea. This study evaluated the water competition between pearl millet and cowpea using deute...
In Japan, wheat-rice crop rotation with the practice of rice transplanting has been quite popular in the past. Mechanized direct-planted wheat-rice sequential cropping was developed at the Aichi Prefe...
A large proportion of soybean flowers abort during development. Pod set is significantly affected by the availability of assimilate and cytokinin in the flowers, but their synergistic effects on pod s...
The yielding abilities of rice varieties were examined among three groups : 10 European and American varieties (E group), 20 Japanese varieties (J group), and 16 high-yielding varieties bred in Asian ...
The partitioning of 13C-labelled photosynthate in eddoe plants(Colocasia esculenta(L.) Schott) was studied. At various stages of development, the whole plants of cv. Uhan were fed with 13CO2.The 13C-l...
The re-accumulation of starch in the stem (culm and leaf sheath) of rice cultivars at harvest was examined from the viewpoint of the sink-source relationship as one of the characteristics of rice who...
Eupatorium [Chromolaena odorata (L.) King and Robinson] is a noxious weed that has the potential to produce large quantities of mineral nutrient-rich biomass, which may be used as a source of organi...
This study was conducted to determine the best combination of azolla ( Azolla anabaena) and N fertilizer under Menemen ecological conditions in 1996 and 1997. The A. mexicana genotype of azolla was br...
