| Abstract: | Diurnal variations in the leaf oils of Valencia oranges [Citrus sinensis (L.) Osbeck] were studied over a period of 4 years. Depending on the season of harvest, a twofold diurnal change in amount of oil can be observed. A quiescent period between flushes was observed in June. The amount of the main individual components varies with the total oil so that the composition of oil shows only small variations. One suggested function for the oil could be as a precursor for higher isoprenoid biosynthesis. |
