Canopy structure and leaf nitrogen distribution in a stand of Lysimachia vulgaris L. as influenced by stand density.

摘要: A hypothesis that a dense stand should develop less uniform distribution of leaf nitrogen through the canopy than an open to increase total photosynthesis was tested with experimentally established stands Lysimachia vulgaris L. The effect density on spatial variation photon flux density, and specific weight within examined. Stand had little value light extinction coefficient, but strongly affected per unit area canopy. more stand. However, different climates between explained only part in increased increasing relative decreasing concentration.
