【 摘 要 】

Petioles of Vitis vinifera Cabernet Sauvignon, Pinot Chardonnay and Sauvignon Blanc were analyzed during eight (8) years for Nitrogen (N), Phosphorus (P), Potassium (K), Calcium (Ca), Magnesium (Mg), Iron (Fe), Copper (Cu), Sodium (Na), Manganese (Mn), Boron (Bo) and Zinc (Zn). Petioles were first dried in a forced air-draft oven at approximately 70°C for 48 hours, then ground and analyzed. Nitrogen was analyzed using microkjeldahl, P by colorimetric method, K and Na by flame emission, Ca, Mg, Fe, Cu, Mn and Zn by atomic absorption spectrometry and B by a colorimetric method using curcumin as a derivatizing agent. Average values for the eight years (8) found in the dry matter (DM) were for Cabernet Sauvignon (g/100g): 1.59N, 0.76P, 3. 28K, 0.93Ca and 0.28Mg and as mg/100g: 11.52Fe, 4.18Cu, 85.08Na, 70.17Mn, 2.07B and 13.97Zn; for Pinot Chardonnay (g/100g): 1.26N, 0.47P, 3.20K, 0.82Ca, 0.31 Mg and as mg/100g: 15.25Fe, 3.25Cu, 63.73Na, 42.91 Mn, 2.08B and 11.13Zn; for Sauvignon Blanc (g/100g): 1.51 N, 0.49P, 2.29K, 0.79Ca, 0,32Mg and as mg/100g: 16.01Fe, 5.91Cu, 76.02Na, 70.61Mn, 1.91B and 11.9Zn.
