2009/8/6
Investigations were made on the effect of isoprothiolane (diisopropyl-1, 3-dithiolan-2-ylidene malonate, IPT) on the ripening of rice (Oryza sativa L.) under the low temperature conditions. The simil...
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...
