砧木和接穗的影响是相互的,营养分配模式及通过接合部位的能力、环境和土壤因素影响的大个、负载量等的变化,主要受砧木和接穗的基因组成所左右。嫁接树砧木的根系代替了接穗的根系,它对接穗的矿质元素含量有很大影响,但是以前的报道认为接穗中原来不存在的物质也不能通过砧木 The effects of rootstocks and scion are mutual, the patterns of nutrient distribution and the ability to pass through the joints, the environmental factors and soil factors, and the changes of the load are mainly influenced by the genetic composition of rootstock and scion. The root system of grafted tree rootstock replaces the root system of the scion, which has a great influence on the mineral element content of the scion. However, it has been reported in the past that the substance that did not exist in the scion can not pass through the rootstock
