Varietal differences in growth response to drought were studied in order to determine major attributes composing drought resistance in the rice plant. Eight rice varieties of different hydrological b...
Potential sink size was correlated with plant nitrogen (N) at late stage of spikelet initiation and flowering, and with growth duration (GD) in DS and WS. The amount of N in plant at critical growth ...
The varietal differences in thickening of storage root was investigated under different supplies of nitrogen and potassium nutrients by gravel culture. Roots were divided into two different functional...
Changes in the eating quality of nine cultivars of rice, including Koshihikari, Nipponbare, and some recently developed varieties, after storage for about one year at room temperature were studied. T...
The study has been carried out to evaluate varietal difference in leaf senescence during the ripening period in relation to sink size and nitrogen application. Leaf senescence was early in the medium...
Transpiration of a rice plant under a low water potential of rooting medium and low air-humidity conditions was studied in order to evaluate varietal difference in response to water stress. Water stre...
Varietal difference of lodging resistance in paddy rice was studied using nine Japanese cultivars and thirteen foreign cultivars (cv. Kamenoo : KA, Aikoku : AK, Koshihikari : KO, Dobashi 1 : DO, Fujim...
Three spring wheat varieties, old tall Haruhikari and modern semi-dwarf Haruyutaka bred in Hokkaido, and tall late Selpek bred in Germany, were sown at a 5cm equi-distant square pattern on 3 sowing da...
To make clear the internal leaf morphology concerned with varietal difference in specific leaf area (SLA) response to concentration of culture solution at the seedling stage, varietal differences in ...
It has been generally believed that the crop ideotype canopy has an erect small leaves to allow the photosynthetically active radiation (PAR) to penetrate deeply. In wheat, this might be not always ap...
The present investigation was undertaken to examine which physical and chemical characteristics of the culm associated with lodging resistance changed under different growth conditions using three var...
In order to investigate the breeding objective on the improvement of rice yield, the yield structures were analyzed and compared among a hundred varieties. By using the mean specific gravity (S), all ...
We investigated which cell wall components of the culm affect the bending stress of the culm using seven rice cultivars. A small difference in the cell wall composition was noticed among the cultivars...
Local soil-reduction occurs around rice seed when it is sown into flooded soil, and the reduction inhibits seedling emergence. Seedling emergence is more inhibited when the reduced soil area is forme...
Eight rice varieties were grown in pots and the varietal difference in the effects of applied gibberellic acid (GA3) on the number of spikelets per panicle were examined. GA3 (5 ppm) was sprayed onto ...
