PRELIMINARY STUDIES ON PLANT FINGERPRINTING OF CREEPING JUNIPER CULTIVARS |
| Author: | T. Fretz |
| Abstract:
Monoterpenes from the foliage of Juniperus horizontalis Moench. 'Plumosa' (Andorra juniper) grown under varying photoperiods and N fertility levels were compared. Increasing levels of supplemental night lighting significantly increased the quantity of  -pinene and  -limonene while all other monoterpenes decreased or remained unchanged.
Only -terpineol showed a significant increase in relation to increasing N fertility.
Of 55 possible cultivar pairs, 54 were significantly different and could be distinguished from one another on the basis of the composition of their monoterpene profiles.
In addition, seasonal monoterpene composition of Andorra juniper showed less fluctuation during the winter months (Nov-Feb).
