Title: Cane and Leaf Growth and Leaf Mineral Nutrients in Various Cultivars of Wine Grapes
Authors: E. Fallahi, B. Shafii, J.C. Stark and B. Fallahi
Abstract:
Cane growth, leaf size, and leaf lamina and petiole mineral nutrients of 15 grape cultivars under climatic conditions
of southwest Idaho (Intermountain West region) were evaluated from 1999-2001. They were: 'Cabernet Franc 01',
'Cabernet Sauvignon 11', 'Carignane 06', 'Dolcetto 01', 'Grenache 03', 'Limberger 02', 'Malbec 06', 'Merlot 08',
'Meunier 01', 'Nebbiolo 01', 'Petite Verdot 01', 'Petite Sirah 03', 'Pinot Noir 18', 'Valdepenase 03', and 'Viognier
01'. 'Valdapenase 03' had longer canes, larger lamina, and heavier leaves while 'Limberger 02' and 'Dolcetto 01'
had shorter canes than several other cultivars. 'Limberger 02' had lower concentrations of lamina N, and 'Nebbiolo 01' had lower petiole nitrate-N than other cultivars. 'Valdepenase 03' and 'Petite Verdot 01' had higher lamina
N than most other cultivars. 'Valdepenase 03' also had higher lamina K but lower lamina and petiole Ca and Mg
than most other cultivars. 'Merlot 08' had higher concentrations of lamina and petiole K as well as petiole Ca
than most other cultivars. 'Grenache 03' had lower concentrations of lamina and petiole Zn than other cultivars
examined. 'Limberger 02' had lower lamina Mn, and 'Valdapenase 01' had lower petiole Mn than other cultivars.
