TABLE 3 analysis of variance of high annual growth of trees after treatment with different hormone combinations
TABLE 4 multiple comparison of high annual growth of trees after treatment with different combination hormones
As shown in figure 1, the phytohormone combination of 150mg/L IAA, 50mg/L NAA, 100mg/L GA (4+7) and 100 mg/L6-BA has positive promotion effect on the high growth of the young red pine forest after the mixed phytohormone treatment.
