Dynamics of non-structural carbohydrates in Pinus pallasiana D. Don needles under different forest growth conditions of ravine anti-erosion plantations

Month	Thalweg	Middle part of the slope	Upper part of the slope
May	0.50 ± 0.03	0.31 ± 0.02^a	0.30 ± 0.03^a
June	0.62 ± 0.03	0.39 ± 0.04^a	0.33 ± 0.03^a
July	0.84 ± 0.04	1.10 ± 0.03^a	1.32 ± 0.05^a^,^b
August	0.89 ± 0.09	1.54 ± 0.05^a	1.65 ± 0.07^a
September	0.99 ± 0.05	1.65 ± 0.06^a	1.72 ± 0.05^a
October	2.50 ± 0.07	2.25 ± 0.08^a	2.05 ± 0.04^a

Note:

a. The difference between the „Thalweg” variant and the „Middle part of the slope”, „Upper part of the slope” variants is statistically significant (P < 0.05);

b. The difference between the „Middle part of the slope” and „Upper part of the slope” variants is statistically significant (P < 0.05).
