Oat (Avena sativa L.) and wheat (Triticum aestivum L.) vary in the structure of their inflores-cences and also in how pollination proceeds within the inflorescence. In both species the grain position ...
The effect of nitrogen top-dressing (ntd) on the gibberellin (GA3, GA) - induced abnormality of spikelets was investigated during the two years, 1986 and 1987, with using the rice cultivar Sachikaze. ...
Morphogenesis of panicle and spikelet in paddy rice, cultivars Yuhkara and Fujihikari was studied by SEM. Germinated seeds planted in containers with submerged soil were cultured under natural condit...
Three high-yielding japonica-indica hybrid (JIH) and semidwarf indica (SDI) rice varieties, and ten japonica (J) rice varieties, including different plant types, were cultivated under sparse (30×30 cm...
A large number of sterile spikelets were induced by low-temperature at the booting stage of rice plants during the middle to the end of July in 1988. The authors investigated various aspects of occur...
The objectives of this study were to clarify the interspecific variation on (i) the structure of spikelet and reproductive organs, (ii) the relationship between the size of spikelets and the reproduct...
To provide new information on salt stress in rice plant based on developmental morphology, structural changes of panicle and spikelet were investigated. As the salt concentration increased, growth and...
The effect of salinity stress on external shoot morphology in relation to panicle development was studied. Three rice cultivars, Nipponbare, as a Japonica-type rice, Blue bonnet as a Javanica-type, an...
The same seedlings of three rice cultivars were transplanted into both paddy fields, experimental fields of Tottori University (Koyama) and skillful farmer's field (Hojo), and given their respective ...
The spikelets produced, amouting to as much as 71, 000 per m2 in a dense-planting plot, had been attained by combining of 487 panicles per m2 and 148.8 spikelets per panicle. The panicle number per m2...
Although the impact of anticipated global warming on regional rice production merits intensive investigation, quantitative information regarding the effects of high temperatures on japonica rice is li...
Callus is an excellent source for in vitro plant regeneration, but plants regenerated from callus sometimes show phenotypic and genotypic variation from the initial plants. In this study, the variatio...
Many field observations have suggested that roots play an important role in the tolerance to the sterillity-type cool-weather damage at booting stage in rice plants. However, how the roots affect fert...
Dense planting is an important cultural technique to increase the number of spikelets per unit area, and is thought to be favorable for grain filling because it increases the percentage of spikelets o...
