Male Sterility Caused by Cooling Treatment at the Young Microspore Stage in Rice Plants : XXIX. The mechanism of enhancement in cool tolerance by raising water temperature before the critical stage
Cool injury Cool tolerance Microspore Pollen Rice Sterility Water temperature
2009/8/6
Potted rice plants were grown in the phytotron with different water temperatures in a range from 18 to 25°C during the period from the spikelet differentiation stage to just before the young microspor...
Male Sterility Caused by Cooling Treatment at the Young Microspore Stage in Rice Plants:XXX. Relation between fertilization and the number of engorged pollen grains among spikelets cooled at different pollen developmental stages
Anther Cool injury Cool temperature Microspore Pollen Rice Sterility
2009/8/6
Cooling treatments at different stages of pollen development lowered the percentage of fertilized spikelets through decreasing the number of engorged pollen grains per anther at anthesis. Cooling duri...
Male Sterility Caused by Cooling Treatment at the Young Microspore Stage in Rice Plants:XXXI. Four components participating in fertilization
Cooling injury Cooling tolerance Fertilization Microspore Pollen Rice
2009/8/5
We divided the developmental processes from microspore differentiation to fertilization into 4 phases and defined the component relating to fertilization in each phase. The percentage of fertilization...

Anther Cool temperature susceptibility Expansin Gene expression High nitrogen PCR Pollen germination
2009/7/21
Changes in gene expression patterns by high nitrogen (High-N) and High-N plus cooling at the young microspore stage (High-N-cooling) in rice mature anthers were analyzed by semiquantitative RT-PCR wit...
Correlation between Spikelet Fertility and Relative Root Amount in Rice Plants Exposed to Cool Temperature at the Young Microspore Stage
Booting stage Cool-temperature tolerance Nitrogen fertilizer Rice plant Root
2009/7/15
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...

2009/7/14
The effects of gibberellin, cytokinin and an inhibitor of gibberellin biosynthesis on spikelet fertility and the number of pollen grains were examined in rice plants which were cooled at the young mic...
Relative Amount and Physiological Activity of Roots Affect the Resistance to Cool Weather at the Young Microspore Stage through the Number of Pollen Grains in Rice Plants
Rice Pollen Number of Pollen Grains Cool-weather resistance Nitrogen
2009/7/7
The relative amount of roots (dry weight ratio of root to shoot, or root dry weight per spikelet) or the physiological activity of roots is correlated with the cool-weather resistance in rice plants. ...
