摘要: The emission rate of isoprene from an oak tree (Quercus serrata) in the field was measured at almost hourly intervals during daytime. showed marked diurnal variation with a maximum around noontime. More than 80% daily occurred between 10:00 and 14:00. correlated light intensity, their relationship could be described by simple hyperbolic function. seasonal September. This differed considerably one presumed average monthly temperatures, indicating need check variations case estimation annual vegetation.
