Abstract
Fast growing eucalyptus species are selected for commercial plantings worldwide and are harvested for a variety of uses.
Eucalyptus plantings in south Florida are harvested for landscape mulch production, yet this material may have potential as a container substrate for horticulture crop production.
In our experiment, eucalyptus was evaluated as a substrate component for greenhouse-grown petunia and marigold.
Eucalyptus (E) was blended with peatmoss (PM) at various volumetric proportions to produce three substrates [E:PM (4:1), E:PM (3:2), and E:PM (2:3)], while two standard substrates were prepared from combinations of PM, pine bark (PB), and/or perlite (P) [PM:P (4:1), and PB:PM:P (3:2:1)]. Substrate pH among all substrates ranged from 4.39 to 5.52 throughout the experiment.
Petunia growth index (GI) was similar for E:PM (2:3), PM:P (4:1), and PB:PM:P (3:2:1), while marigold GI was similar among all substrates.
Chlorophyll content for petunia and marigold was greater in PM:P (4:1) and PB:PM:P (3:2:1) compared to the other three substrates.
