| Abstract | Freshly harvested mature seeds of Hopea mollissima were used in the present study to examine the effect of temperature (10 degrees C, 15 degrees C, 20 degrees C, 25 degrees C, 30 degrees C, 35 degrees C and 20/30 degrees C) on germination, the desiccation tolerance of seed under slow and rapid dehydration, and the effects of storage temperature (4 degrees C, 10 degrees C and 15 degrees C) and moisture content (0.79 g H(2)Og(-1) DW, 0.62 g H(2)Og(-1) DW, 0.57 g H(2)Og(-1) DW) on storage behaviour. The results showed that seeds of H. mollissima had a higher germination and shorter germination time at 15 degrees C than at other temperatures. Germination decreased during dehydration as seed moisture content decreased, but the hazardous effect of slow drying on germination was more pronounced than that of fast drying. The higher seed moisture content (0.79g H(2)Og(-1) DW) combined with the storage temperature of 15 degrees C was most suitable for the conservation of seeds in H. mollissima. |
