Rice yield is reduced by a short period of water stress at the early panicle-development stage. This study was conducted to examine the factors that reduce the panicle dry weight of rice subjected to ...
There are two growth types of plants for the number of developed leaves, heading time, and culm and panicle lengths within a population of a homozygous rice cultivar. However, this phenomenon has not ...
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...
In order to clarify the characteristics of high yielding rice varieties, total dry matter production, yield and harvest index were compared in 1988 and 1989 among the two early and three medium variet...
The increase of heading time in proportion to cumulative water stress (an integrated estimate of the degree and duration of water stress) was demonstrated in a wetland rice cultivar Koshihikari subjec...
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 relationships between number of spikelets per panicle and the characters of shoot and the size around growing point at panicle initiation stage were studied with the rice varieties bearing much d...
Rice panicles start to transpire just after heading. We can therefore expect that the water potential of panicles changes little prior to heading and varies in response to transpiration after heading...
Decrease of panicle weight per plant in rice in proportion to cumulative water stress (an integrated estimate of the degree and duration of water stress) has been demonstrated in rice subjected to inc...
Experiments were conducted to examine whether the responses in panicle water potential under drought changes with panicle development. Twenty seedlings of two rice cultivars, Norin 20 and Milyang 23, ...
Tillering of the 2nd to 11th main stem nodes in potted directed-seeded rice plants was artificially controlled by the removal of tillers on specific nodes. Treatments consisted of limiting tillering o...
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 ...
The protein and amylose content of milled rice grains collected from the top and base rachis branches at different positions on the panicle were measured. The palatability of the grains on primary and...
The effects of drought on the rice yield differ depending on the time when plants are subjected to the drought. It is therefore probable that water stress susceptibility, the degree of yield reduction...
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...
