- Abstract:
- The study of Robinia pseudoacacia leaf ecological stoichiometry in Loess Plateau can help to explain the effect of environmental factors on leaf nutrient and ecological stoichiometry. We determined contents of C, N, P and their ratios, spatial pattern in leaves of Robinia pseudoacacia and relationships between soil and leaf at 14 sites in Loess Plateau. The results show that the arithmetic means of leaf C, N, P contents were 454.63, 21.38, 2.09 mg/g, respectively. The arithmetic means of C/P, C/N, N/P were 226.51, 21.61, 10.73, respectively. There was no significant difference between the contents of these three elements in leaves on shade slope and those on sunny slope. Contents of C, N, P in leaves and their ratios had the same tendencies of geographic spatial pattern on shade slope and sunny slope. Leaf C increased at first and then decreased as latitude increased; leaf N, P increased as latitude increased and only leaf C was significantly correlated with latitude (0.01 < P < 0.05), others did not meet the significant level. In leaf nutrient content, only the C had a significant negative correlation relationship with soil C, N contents, N and P did not show significant changes with latitude and soil content. This illustrates that the leaf N, P element contents are conservative, and are less affected by environmental factors.
