Fig. 2 Germination percentage of seeds of eight plant species under various storages. BS, before storage; I, stored in refrigerator ((4 ± 1) °C, wet seed); II, stored in cold room in winter ((-5 ± 1) °C, wet seed); III, stored outdoors in winter (-26-10 °C, wet seed); IV, stored at room temperature (20 °C, dry seeds). Seed germination at same temperature of incubation with different storage conditions and at same storage condition under different temperatures of incubation were compared by the least significant difference test (LSD) at 5% level (The capital and lowercase letters represent the differences of germination, respectively, under two kinds of incubation temperatures following various storages, and different letters indicate significant difference).
