摘要：
Broad leaf mahogany (Swietenia macrophylla King, Family: Meliaceae) is one of the best-known and most valuable tropical timber. It is almost unique silviculturally and occupies important position in the rural economy of India as a commercial plantation crop. This present study is mainly focused on temporal discrepancy of foliar nutrients and retranslocation of nitrogen, phosphorous, potassium and sulphur in S. macrophylla. The monthly variations in foliar nutrient concentrations and retranslocation prior to leaf fall were analyzed. Results indicated clear autumnal foliar retranslocation of nitrogen, phosphorus and potassium under pure mahogany plantation.
