种子的发芽率除受树种本身的遗传特性影响外 ,还受贮藏条件 (温度、温度、通气状况 )和贮藏年限的影响 ,贮藏期间种子的含水量也是影响种子发芽率的重要因子。白榆、桑树种子适宜随采随播 ,否则 ,会降低发芽率。不能及时播种应密封干藏。为探讨白榆和桑树种子在密闭、低温条件 In addition to the genetic characteristics of the tree itself, the seed germination rate is also affected by the storage conditions (temperature, temperature, aeration) and the shelf life of the seeds. The moisture content of the seeds during storage is also an important factor affecting the seed germination rate. White elm, mulberry seeds suitable for broadcast along with mining, otherwise, will reduce the germination rate. Not timely sowing should be sealed dry storage. To explore the white elm and mulberry seeds in airtight, low temperature conditions
