Sterility Caused by Cooling Treatment at the Flowering Stage in Rice Plants:IV. Effects of the starting time of cooling, morning and evening, and the soil temperatures and the light conditions after cooling on the fertility
Cool temperature Diurnal variation Flowering stage Rice Sterility
2009/8/6
Effect of the starting time of cooling at the flowering stage together with the effects of water temperatures and light conditions after cooling on the fertility percentage were examined. The fertilit...
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...

Boric acid Incubation temperature In vitro germination Pollen Rice
2009/8/6
Rice pollen grains germinated more than 80% with low variation (standard deviation less than 10%) and their pollen tubes elongated to more than 150μm within one hour with a simple medium composed of 1...
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...
