Fig. 1.

Germination percentages (mean ± s.e.) of fresh Kalidium gracile seeds incubated at various temperature regimes in light (12 h photoperiod) and continuous darkness. Bars with the same upper case letter are not significantly different (P > 0·05) across all temperature regimes in light or darkness. The same lower case letter indicates no significant difference (P > 0·05) between germination percentages in light and in continuous darkness for the same thermoperiod. Error bars are means ± s.e.
