FIGURE 6 PAL activity of A. trifoliata in different
habitats
It can be seen from Figure 7 that the 4CL activity of roots, stems and
leaves in rocky desertification habitat of Guanling base was higher than
that in normal habitat, and the difference first increases and then
decreases, and the difference was the largest in August, with the
increase of 1.23 times in roots, 1.19 times in stems and 1.30 times in
leaves; In Huaxi base, the activity of 4CL in roots, stems and leaves in
rocky desertification habitat was higher than that in normal habitat,
and different parts showed different trends, but the difference of
roots, stems and leaves was the largest in April, increased by 1.35
times, 1.29 times and 1.24 times respectively. In conclusion, A.
trifoliata could significantly increase 4CL activity in roots, stems
and leaves in rocky desertification habitat.
