2009/8/6
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...
Sterile Spikelets of Rice Plants Induced by Low Temperature in 1988:Difference in heading date among stems and spikelet locations on the panicle
Heading date Main stem Rice plants Spikelet locations on the panicle Sterility Susceptibility to low temperature
2009/8/6
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...
