Abstract
In order to make clear the diurnal variation of plant volatiles，we collected the VOCs from Cinnamomum camphora flowers using the dynamic headspace air-circulation method at 7：30，10：00，12：30，15：00 and 17：30，identified the main compounds of VOCs with thermal desorption system/gas chromatography/mass spectrum （TDS-GC-MS）. Results showed that C. camphora flowers emitted 51 types of VOCs，mainly as terpenoids. At 15：00，species and emission of the VOCs were highest （40 species and 8 049.5 peak area units），mainly as linalool （relative content 37.0%），epoxylinalol （12.7%）， （Z-ocimene （7.2%） and perillene（6.2%）. Thus，increases in species and emissions of the VOCs from C. camphora flowers at 15：00 are both visibly increased revealed a possible affinity have strong relevance for strong light and high temperature stress. ［Ch，3 fig. 1 tab. 15 ref.］
