Abstract
Canopy growth, as measured by cane length and leaf size, and leaf lamina and petiole mineral nutrients of 15 grape cultivar clones under climatic conditions of southwest Idaho (Intermountain West Region) were evaluated during 1999-2001. The cultivar clones were as follows: ‘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 and larger lamina and heavier leaves while ‘Limberger 02’ and ‘Dolcetto 01’ had shorter canes than several other cultivars clones in all three years of evaluations. Cane growth strongly correlated with lamina N concentration but not petiole nitrate-N. ‘Limberger 02’ always had lower concentrations of lamina N and petiole Nitrate-N and ‘Nebbiolo 01’ consistently had lower petiole nitrate-N during 1999-2001 seasons. ‘Valdepenase 03’ and ‘Petite Verdot 01’ had higher 3-year average lamina N than most other cultivars clones. ‘Valdepenase 03’ also had higher lamina K but lower lamina Ca and Mg than most other cultivar clones. ‘Merlot 08’ had higher concentrations of lamina and petiole K as well as petiole Ca than most other cultivar clones. ‘Grenache 03’ often had lower concentrations of lamina and petiole Zn than other cultivars examined. ‘Limberger 02’ always had lower lamina Mn and ‘Valdapenase 01’ had lower petiole Mn than other cultivar clones.
