According to the “fruit tree” 2014 the fourth period “autumn cut root treatment is more conducive to the safety of apple overwintering in Weibei Loess Plateau” (author Zhou Ke-You, etc.) reported that the “Fuji” apple seedlings as the test material, Methods and high performance liquid chromatography (HPLC) were used to analyze the changes of 1-year-old phloem, perennial phloem and root sugar and the related enzyme activities. The results showed that the contents of sucrose and sorbitol in the phloem and perennial branches of perennial branches and phloem of perennial branches increased significantly after rooting, while the annual and perennial phloem
