The induction of seed chitinases by fungal attack has been demonstrated in some monocot species during both maturation and germination. All except one of the 72 pre-burn soil samples (99%) contained germinating dicot seed and 40 (56%) contained germinating monocot seed. The soil seed bank from the 1-y-old post-burn soil was dominated by monocots (96.5%). The great majority of whiteflies in existence today colonize only dicotyledonous angiosperms and a smaller, but significant, number feed on monocots, particularly grasses and palms. Various arborescent monocots are found scattered in the mid-storey eucalypt woodlands or as co-dominants in the canopy adjacent to wetlands. Weeds were either pooled as one group, or separated into dicots and monocots. In 1994, reference forest soils produced 422 seedlings (703 seeds m-2), 368 (87%) dicots and 54 (13%) monocots. Therefore, monocots are better able to deal with the typical water stressed habitat of the lowland canopy than dicots. Thus, in both monocot and dicot seeds, loss of dormancy was associated with a reduction in the threshold oxygen percentage. Unidentified species (monocot and dicot classes comprising 13.5% of the emerged seeds) were excluded from the analyses. This is the highly modified cotyledon of monocots that transmits hormones, produces digestive enzymes, and transports nutrients from the endosperm to the embryo. Evolution has, therefore, shaped monocot germination and endosperm mobilization into a highly regulated process. One-year post-burn soil was dominated by monocots; only 3% of the seedlings were herbs; no vines, small trees/shrubs or trees germinated. A total of 2101 seedlings (3503 seeds m-2) germinated from the 1-y post-burn pasture soils, 74 (4%) dicots and 2027 (96%) monocots. Only 14 of the 72 1-day post-burn soils (19%) contained germinating dicot seed, and none contained germinating monocot seed. Only dicot species were used in this analysis because monocot seedlings were not identified by species. This is an annual monocot that is quite variable in appearance.
