Summary of the final report on the Australian Flora Foundation funded project:
Epacris impressa Labill.: Inoculation of cuttings with ericoid mycorrhizal
and DNA fingerprinting of floral races
This study examined the use of ericoid mycorrhizal fungus as an inoculum to stimulate root and shoot production from cuttings. The fungus did not provide any benefits to root and shoot growth or health, but methods for improved propagation success rates were developed during the experiments.
fingerprinting techniques were also used to examine relationships between
geographic sites and flower colour populations and to aid in
provenance determination. Results indicated that E. impressa has
a high level of both inter-site and intra-site genetic diversity.
white floral races had a high level of shared genetic traits while
the pink-flowered race had a more distinct genetic identity. The
suggested that the pink-flowered populations have developed into
a separate floral colour race rather than an F1 hybrid between red
and white races.
