The Study of the Effect of Temperature and Storage Period on the Germination of the Oak Seeds (Quercus Castaneifolia)

To study the effect of storage time on the germination of oak seeds, the selected seeds were stored at , -1, -8 temperatures under the cool house conditions. Then we dealt with the sampling and culturing of seeds after one week, two weeks, three weeks, one month, two months, four months and six months intervals. The seeds were cultured in two methods (with sand bed and non sand bed). Then the germination was measured. The results showed that germination had a decreasing process with the passage of storage time, but it was lower in seeds with no bed. The results also indicated that the germination of seeds takes place in a shorter period after two months of their storage. In addition, the seeds will not germinate while stored under 4°C, and if their storage period is increased for more than 2 months. By surveying the seeds stored under -8°C, we observed that they would be frozen and destroyed after three months. The general conclusion is that seeds can be stored for a short period at 4°C, whereas for a longer period, they should be stored under -1 or lower temperatures.
