Abstract:This paper was carried out to clear the distribution of mineral nutrition in leaves and stems of Vaccinium uliginosum among different ages of basal branches in Daxing’an Mountains and explore the relations between mineral nutrition and the growth in V. uliginosum, we analyzed the contents of N, P, K, Ca, Mg, Mn among different ages of basal branches including 12year branches (S1), 3year branches (S2), 4year branches (S3), 5year branches (S4), approaching old branches (S5) and old branches (S6) conceived from the base of bushwood. The results indicated that: (1) six elements showed different patterns in leaves and stems. N, P, K had a tendency to decrease as branches became old, leaves and stems sunk the minimum at S5, S6, respectively. The content of Ca was accumulated at old branches, Mg and Mn both had no significant differences among different branches; the contents of N, P, K, Ca, Mg showed the following tendency: leaves were obviously higher than stems, Mn content of stems was slightly higher than that of leaves in wet land with grass. (2) The new shoot growth of V. uliginosum had positive correlation with K and Mg in leaves and N, K, Mg in stems, and had negative correlation with Ca and Mn in leaves and Ca in stems. (3) Canonical correlation analysis showed that the factors of mineral nutrition which effected new shoot growth were differ from the ages of basal branches; in S1, the new shoot was mainly related to Mg in leaves, the new shoot was effected by K, Ca and Mg in stems during S2-S4, and the content of Ca in leaves mainly influenced the growth of new shoot. (4) The senescence of V. uliginosum may be related to the accumulation of Ca.
