| Abstract: | The physiological susceptible period to cold temperature,thecritical period of the climtae and the leading climatic factors of thechilling injury of barley have been studied by means of the fieldexperiment and artificial simulated cold temperature test.The resultsshow that the most sensitive period of the chilling injury to the barleyis in the five days before boot stage,at this time the growth of theyoung ears steps into the period from meiosis to tetrad.Mean tempera-ture and mean minimum temperature in this period are the main climaticfactors leading to the chilling injury.The higher maximum temperaturecan reduce the level of the chilling injury.The time from the lasteight-days of Feb.to the middle ten-days of March in Chongqing is thecritical period of the chilling injury of barley. |
