Fig. 1. Germination (%) of Hosta sieboldiana seeds after storage at ~5%, ~10% and ~65%moisture content and at 5 °C (open circle, dotted line) and−20 °C (closed circle, solid line). Values
are means of three replicates of 50 seeds for the germination tests. Solid and dotted lines represent the selected models of storage time versus germination at 5 °C and−20 °C. Details of the
models are given in Table 1.
